PCalc Positive Reviews

It can be anything you want it to beI have downloaded (and bought) many iPhone calculators and PCalc is by far the best. The depth and breadth of this app is a true labor of love by the author who has spend decades perfecting it (see his website). As an RPN lover and HP calculator addict, I have searched for and tried most of the offerings in the app store only to be disapointed by the rediculous skeuomorphic designs that abound. With PCalc, the amount of custimization possibilities is dizzyingly vast but, once the shock of available options wears off, you are rewarded with a true sense of empowerment. Case in point: I love the elegance and simplicity of the original HP35 from 1972. I was able to duplicate this keyboard layout and, with the appropriate theme, I was able get it looking very nice. This took me a while but my layout is automatically saved to iCloud where it syncs with my other iOS devices. The layout customization is very sophisticated, allowing you to have keys that are hidden until the 2nd key is pressed. All the labels for each key can be set to whatever you want. I'll stop here not because there is not more to say, but because this calculator shines once you start exploring the many options available. The point being, if you don't like what you see in the default layouts, you can make it be anything you want it to be..Frank HellwigVersion: 3.8.8

I know calculatorsThis is by a wide margin the best ‘quick’ calculator software ever developed. i love how it allows me to obsess over fine-tuning my layout exactly how i like it. with any program that invites the user to invest this level energy into of customizing their experience, there will always be things i start to notice that i just really wish were present. with this app, the one thing i would like to point out to the developer is that most classic RPN calculators allow the user to combine a STO/RCL operation with plus/minus/times/divide. for instance, you can do things like STO * 2 or RCL / 7. i use these types of operations a lot on my calculators and i find them to be intuitive and convenient. although the multiple memory in this app has a pretty good and authentic interface, it’s missing this one feature I like, and there doesn’t seem to be a good workaround. I’ve tried writing macros and putting custom buttons in my layouts but i can’t really see any good way to replicate this feature. the storied development of this app is obviously a labor of love and i look forward to see what features come out next..LennyhpivVersion: 3.12.1

Best Calculator App, Period.This thing is the Disneyland of calculator apps. The developer is a genius. Every feature you could possibly want, or might one day in the future discover you want, is in here. But none of that vast array of features results in any unnecessary complexity. PCalc is totally user customizable, enabling you to create just the feature set and look and feel that you desire. Also, every other calc app I have tried has either lagged or mis-registered touches, but PCalc is smooth as silk, which is crucial for a calculator. I never thought I would even review, much less rave about a calculator app, but not only does PCalc work like a dream, but it has such incredible attention to detail and customizability that it's actually a ton of fun just to play around with the endless variations. But wait, there's more. As if this thing couldn't possibly get any better, in the latest version the developer has added what can only be described as a 3-D graphics wonderland as a hidden bonus. Simply tap the "i" key, then "Help", then "About PCalc" and prepare to be amazed. You just have to try it; I don't want to spoil the surprise..Logan500Version: 3.7

Sure, there are lots of calculators...... But none like this! Pcalc has been around for a long, long time and is available on both iOS and macOS. However, the iOS version seems to be getting most of the love from the very talented author, and that's okay by me: I'm more likely to have an iOS device handy these days and I now find excuses to use this attractive and powerful app. I use it daily for various units conversions and general calculating. I fell in love as soon as I discovered it had an RPN mode. Easily mastered, RPN is intuitive and eliminates any ambiguity over operator precedence in complex calculations. My nearly 40 year-old HP calculator still sits in a lonely drawer; I'd rather use Pcalc, now. If you have an iPad Pro, the latest release has a delightful Easter egg that demonstrates the considerable computing and graphics power, while allowing the author to show off his programming chops. As an old-timer, I'm impressed!.TheKemerVersion: 3.7

Super Happy HP 48G User 😊*Finally* found a great calculator! 🧮🙏🏼 I’m a chemist 👨🏻‍🔬, used to using an HP 48G, and simulators for that have come and—sadly—gone. 😱😭 This one’s not a simulator, but has numerous, super thoughtful settings that (among many other options) allow you to set it up in a way that’s very familiar and useful for people accustomed to the HP 48G—or whatever other system you’re used to. (Just for calculation functions; for programming and graphing, probably look elsewhere.) For those who prefer not to use RPN, no problem: standard notation is default. Unlike Calcularium—which I’ve been using, but has become unusable since iOS 14—PCalc starts right up without communicating with the mothership 🛸 or any other delay or funny business, and accepts input and works *fast*. Units conversions are a breeze. You can edit button functions! Also edit: visible stack levels, digit color, font (I like LCD Bold), precision, etc. Choose light and dark themes (I like Flynn with Dark Orange digits) and app icon (I like Circuits). The Apple Watch app features a nice tip calculator. On the iPhone, this app enjoys pride of place, close to my right thumb, among my Camera, Chrome, and Calendar. Cheers! 🍻.AlopekiasVersion: 3.10.2

The calculator app that is actually made by people who care about calculators.I’ve tried lots of calculator apps. A calculator is usually one of the first apps that a developer makes because it is relatively easy to make a simple calculator and skin it to look pretty. This app was not a weekend project or a simple calculator that looks good. This is the calculator app that is made by calculator enthusiasts. The customizability is insanely accessible. Not only can you create entirely new button layouts, but the core functionality can be tuned to fit your workflow. This app is created and maintained by a developer who uses their passion to directly benefit their customer. I rarely see such dedication towards providing a functional product. This app even includes settings for Reverse Polish Notation (RPN) calculators. A calculator workflow that is obscure, but loved by many. I still use Wolfram|Alpha for graphs and really complex stuff, but PCalc offers the best basic calculator option around. Even the widget is well thought-out!.XuisVersion: 3.7.6

Amazing, but missing construction supportSuch a great calculator, so many options, I really wish I could use it. There is no support for displaying numerals in inches/feet. You can put things in fraction mode, but it gives you answers outside of base 32 like 4/5ths which is really not helpful. if only you could tell it to round to the nearest 8th or 16th, but rounding is based on decimals. You can give it a minimum denominator, but it still displays answers outside of base 32 which is really frustrating when I can make it do radians or binary, but not base 32 fractions which is a number systems that has been around forever. Love the calculator and all the customizable features, but it just won’t do what I need so I will have to stick to my bad construction calculator for the time being..KylereardonVersion: 3.10.2

Best Calculator I’ve Ever UsedI am a retired biochemist. I used a slide rule for the first 10 years of my career and then the finest HP calculators that were available until I retired. This PCalc is as good or better for my purposes than any other calculator I have ever owned. I use strictly RPN, and there are a couple of quirks that you have to get use to, e.g. you have to use the “swap” key when solving combinatorics with the built in combination and permutation keys, which is anti intuitive, but easy to get use to. Overall this is a really nice calculator and I can recommend it for most common math applications with no reservations..GwmelchiVersion: 3.7.7

Genius. Essential. Permanent home page spot.Modifiable keyboard (main and 2nd), programmable functions, decimal/hex/octal/binary bases, keyboard/result formats for engineering , accounting, scientific, and others. Built-in conversions (pounds to ounces, miles to kilometers, etc). Constants (speed of light, local tax rate, etc). Used multiple times daily. Makes iPad/iPhone a true computer. First app I bought when I first got into Apple in 2004. Favorite of all apps. Does everything a calculator should do, and more. JT is a man with a great sense of humor. The world needs him. You need this app. 42..FjpoblamVersion: 3.13.1

Needs 64 Bit SupportPCalc is a good app but if it is going to provide number base operations (hex, octal, decimal, binary) then it needs to add 64 bit support. Even cell phones are 64 bit. Software developers work in 64 bit environments while PCalc only provides support for 48 bits. I have emailed the developer at least 4 times since 2011 and still no 64 bit support. Lack of 64 bit support is inexcusable in this day and age. The best calculator for iOS bar none is free and the name of the app is Sci:Pro. It is 64 bit and has everything that you need at no cost. I give PCalc 3 start because it does everything else very well, but if you want to save some money and deal with a very responsive app developer, give Sci:Pro a try..Jim92677Version: 3.8.2

Used it for yearsI have used PCalc for years, probably since it was first released, and it’s still the first app I add to my systems when I get a new one, whether it’s the desktop, iPad or iPhone version. Over the years I’ve focused on the developer tools it offers, and scientific functionality, and now it’s currency conversion when we travel. I have never found another calculator that offers the same functionality, and the only thing I wished it could do was graphing of functions..GmfergusonVersion: 3.12.2

Works great – ANIMATED PANDAS!This app runs circles around any other calculator in the App Store, and is well worth the price. No problem installing it on phone or Watch, also version for TV and macOS, and functions great on all devices. App author is very responsive & regularly updates the app with new features. if you run into a problem email or Twitter him instead of writing negative reviews! Holy 💩! Animated 🐼 stickers now! This calculator app does everything you could dream up — except for a kitchen sink — but it can calculate the size of one if you give it the dimensions!.Iphonereviewer#2Version: 3.8

Incredibly cool, deep and reliableI’ve found no calculator app even close to this; and I went through a lot of them before finding it. In addition to being a great calculator in general even for long numbers, it has a deep set of conversions, constants and functions. I’ve been using it for years. Works great on iPad, iPhone and even has a Apple Watch app that works. I’ve never been caught upgrading iOS and finding its broken afterwards, unlike way too many apps. I use it so much it’s on my menu bar on my iPad..OregonWaveVersion: 3.9.5

Feature request: favorites for conversionsI love PCalc and use it almost daily as a scientist. If I were to add one feature, I would add the ability to select “favorites” from the different unit conversions and then have them grouped into their own category. I frequently use conversions from different categories, which means lots of scrolling and selecting. If I could pick the 5 most common as favorites, it would save me a lot of effort. Keep up the great work on this program!.GusnorthVersion: 3.10.2

The best calculator for iOS period.I originally bought and updated the light version to get all the functionality. When I got a chance I also bought the full version since I hated the app showing the ‘lite’ version on my phone. Hey the developer has to eat too! This is my goto calculator period. Does everything and more. It also is the best functioning Apple Watch calculator. Buy it! The developer is great, responsive and updates frequently!.WentzelVersion: 3.7.3

Best Calculator Of Any KindA long-time user of PCalc lite, I recently upgraded to the full version. I am delighted. This is the best calculator of ANY kind. As a physicist, mathematician and programmer I really appreciate the easy access to constants of all kinds, unit conversions, base arithmetic, RPN. It’s all in there. It turns my iPad into the ultimate calculator and numerical tool. Better yet, it requires no documentation. It all works the way you would expect it to. Get it now—you will not be disappointed..E-PaulVersion: 3.7.2

Needs TVM capabilityI’ve been using PCalc for years and it’s a great calculator and extremely customizable. Unfortunately for far too long it’s not offered even a simple time value of money feature. Please please please finally add a simple set of built-in loan calculation features. I have no doubt of your ability to add this feature, it seems the only thing stopping it from happening is the developer is being a purist and simply doesn’t want to. Adding TVM would makes PCalc perfect!.BobP63Version: 3.9.5

Awesome Calculator, Awesome DeveloperBest Calc app that I have used. Have lots of Calc apps but this is the one I keep coming back to for all needs. Engineering, Math, and even casual grocery store stuff. The nicest thing is this developer actually understands and supports all of the iOS versions that are claimed to be supported. Can't say that for other developers, some even "big name" developers. Thank you guys for a great product!!!.__JN__Version: 3.8.6

Great calculatorEdit: I don't know when but at some point an option to choose from many app icons was added. It requires a tip, which is fine, except I do think the option to revert to the icon in place when you bought the app should be free. This is the only calculator I use, and it's the best RPN calculator I've found. I really dislike the updated logo compared to the older simpler (matched iOS style better), and it looks completely out of place on my home screen now..Jack IsidoreVersion: 3.7

Best alternate for the now defunct M48+Would be perfect if it had units associated with data. I was a long user of HP48s and the the M48+ app. Sadly when I upgraded my iPad recently I found that M48+ is no longer available. PCalc seems to be the closest match. Programming is not near as nice as HP48 style. Also PCalc cannot work with units tagged data. It does have units conversions but the unit is not associated with the data. The best feature of PCalc is the customized key layouts. You can setup layouts for different types of work that needs to be done..EsorccVersion: 3.8.7

Simply the BEST Calculator!I have probably bought over 14 calculators for IOS, and downloaded to test an equal number. If I had downloaded PCalc first, I could have saved myself time and money. I really appreciate when a developer allows me to customize their app. After customization, PCalc is MINE. It looks and works as if a developer had written it for me and my tastes. I LOVE PCcalc! It has ‘pride of place’ on all my devices..JoyceM14Version: 3.9.3

Yes, I Paid for this AppIt does more than I'll ever need, but includes multiple memories, paper tape, RPN toggle, AND a downloadable FREE MANUAL. The manual is understandable. Finally, you can slick the interface down so you have a clean screen with the tools you don't need stashed out of the way (I dislike doitall on one screen Cuz it's cluttery). Well, a last comment: I love the 42 homage to Douglas Adams answer to "life, the universe and everything 😎.SfwendieVersion: 3.7.5

Great calculator; watch complication needs workObviously this is the best calculator on the phone. But the watch complication work is not there. Friendly suggestions: 1) offer a variety of options for what the various complications look like. 2) offer an infograph modular complication that displays info from the calculator, at least showing numbers or constants or something... 3) the top of the infograph complication should serve a similar purpose with text. Use the watch guys!!.OK_NYC11Version: 3.8.4

Widget Key Click❓Updated review, 30 January 2023: Developer’s response makes no sense; I’m referring to widget key click sounds, not currency rates. However, I did have a problem with currency rate updates several years ago… 24 December 2022: Minor bug…the ‘squeak’ key click no longer produces any sound on the PCalc widget. The ‘classic’ key click tone, however, appears to function flawlessly. Go figure….SchoowaVersion: 3.12.1

It just works. Really.PCalc has lots of features but no feature-brag: You can customize layout, appearance, behavior… to the point where any more would be satirical. What’s left after you have molded PCalc to the way you work is a calculator that does what you ask of it, crisply and without fuss. It does one thing well, and gets out of your way. It’s not an easy balance to strike..WT9TVersion: 3.7.6

I love the tape!I love the tape feature! I’m studying for the CPA exam and this app is a godsend! It saves me so much time! No more having to countlessly go back and run calls again because I think I forgot or fat fingered a number. Parentheses for calculating net of tax too! 😯 I wish I knew what this calculator could do when it went on sale during Christmas but 9.99 is way worth it. In time savings alone!.Quietstorm81Version: 3.7.4

Great App and Responsive DeveloperI’ve been using this app for a number of years. It’s a full-featured calculator with lots of customization options. I recently had a few questions regarding the app, and I received a really quick response from the developer who answered my questions. Highly recommended..EripetraVersion: 3.10.5

Issue ResolvedI’ve always loved this app and I’m still a fan, but there is an issue with PCalc not retaining calculations once I go from the app to the home screen (or swipe to another app) and then go back into the app. I thought this may be an issue with iOS 11 being poor at memory management, but I restarted my phone, only opened up PCalc and had the same results (UPDATE) This turns out to be a setting under the Advanced section. Once I unchecked the Clear On Open option the behavior returned to what I expected. My rating is back to 5 stars, though I don’t know how that option got set as I wasn’t even aware of the Advanced Settings section.Eb1171Version: 3.7.4

AmazingLike the many other reviews on here I want to start off by saying that as a college student/programmer this calculator is very underpriced for the availability of options that are given. It’s so simple and powerful and it is the best thing that I have downloaded on the ios App Store. Shocked at how customizable it is, the developers really threw in elbow grease here I’m very thankful..Nyrican14Version: 3.9.5

Using since launch, no widget now?Using on my iPad only, and once I found out the reason why no calculator for iPad… this one should be the standard, but I do not see a widget anymore. If there is a reason why, please tell or I hope it is not an issue with the recent update for iOS 15..NPhrymeVersion: 3.11

No better calculator on any platformPCalc is customizable in more ways than I’ll ever use, looks great on iPad, iPhone, and Mac, and unlike calculators from certain large fruity companies, doesn’t have any difficulty with how fast you enter digits. It does RPN, too, if you’re a fan of old school HP calculators as I am. Nothing but praise for this app and its developer..VPNavyFSVersion: 3.7.2

The best calc app.I enjoy using this app for the following reasons: the multitude of interchangeable appearances, colors, styles & layouts, converting units, calculating in normal - engineering - scientific - accounting - fractional modes. I dislike viewing the delayed branding on startup, which inclines me to use my native iOS calculator app for visual simplicity. I would also prefer one less step to enter fractional calculations..MICHANICAL™Version: 3.8.8

Best calculator appThis is the best calculator app around. It is a combination of a good engineering/scientific calculator and a programmer’s calculator. The stack and RPN features are familiar and comfortable if you are accustomed to HP calculators. The app on Mac and iPhone work the same ways. It is nice to have the same app, regardless of whether I’m using the phone, pad, desktop, or laptop..VantelimusVersion: 3.13.1

Looking forward for edit numbers on screenGreat calculator! Cannot wait for an update that allows me to edit the numbers on a tape or from the screen. Saves major time and I doesn't have to keep swiping left and retyping everything again. Thank you.ObadiahcruzVersion: 3.8.7

Great calculator app, butIt's $10 up front and the dev locks some other features behind another paywall, this time described as a "tip" jar. Here's the thing: it doesn't count as "tipping" or "donating" if you have to pay that money to access other features. I paid $10 non refundable, I wasn't expecting to be asked to pay more. For this reason I am docking a star.LeeTheMusicBeeVersion: 3.8.8

Worth getting just for the AR zaninessThis is the best calculator. Period/full stop. I’ve had it for years. It’s a go-to in almost every situation. But it just got better thanks to the dev’s whimsical AR Easter Egg. If you have iOS 11 and a supported device (I have iPhone 7+) then you owe it to yourself to buy the app just so you can see the magic of AR..*** Diabl0 ***Version: 3.7

GREAT APP- Terribly BAD timing on my partThis is a great calculator and I have been using the lite version for some time. This morning I purchased the full version and not twelve hours later it is deeply discounted. It would be great if the developer would refund a portion of the purchase. If not it is still a great calculator and worth the cost..Bob GorskiVersion: 3.7.3

New Style Widget doesn’t workNew style widget doesn’t work but old style does in iOS 16. Wish this was more clear in the description. The old style widget can’t be added to home screens and can only show up below all new style widgets on the widget screen. It’s helpful but sub optimal. Will change this to a 5 star review if this all made more clear in the App Store description..Bart3355Version: 3.12

It Really is "The Best Calculator"I like calculator apps and have purchased many of the most popular ones. All have their special uses, but the one I reach for 99% of the time is PCALC. It can be simple, or as complex as you want depending on the options you select. Keyboard support is exceptionally complete. Simply a brilliant application..I like to calculateVersion: 3.10.5

Used to be great BUT...UPDATED 7/7/18Tech finally got back to me and suggested a reset that worked and restored everything back to normal...so revised back to 5 stars! Ever since iOS 11, whenever I attempt to download/operate it, all I get is a fragmented keyboard and multiple blank squares. Hoping one day it will get fixed..DennismkVersion: 3.7.6

Would love to see crypto currency conversions addedFor trading or moving money between countries, currencies, and just doing calculations, this would be a big help. I already have formulas made for currency conversion, but this would be really helpful, especially since the figures change so rapidly..PbasshamVersion: 3.7.5

Worth the $$I just bought this app and i have to say its great. Definitely the best calcualtor app out there. I really like the conversions, which i use a lot. A nice addition would be to add in a Construction Calculator for Feet and Inches. I would be willing to pay another $15 just for that. Please consider adding this calculator..Dino62960Version: 3.7.3

Worthy Replacement for HP 41 CVMy trusty HP 41CV finally died after 30 years of faithful service. This app is a great replacement for it. It has all the old functionality and simplicity I loved but so much more. You can customize just about anything and create any functions you want. Well done..Danger boy JohnVersion: 3.7.4

Thanks Mr Thompson!Got quite a laugh reading the release to find the addition of the Hackett #. You’re the best for many reasons, not the least of which is your willingness to participate in some shenanigans every now and then. For anyone who hasn’t bought yet, do so immediately..Fraggin' awesomeVersion: 3.9.5

PersonalizationJust, the themes!! Go from classic Mac & Tron (mechanical keyboard sounds too!) all the way to the wonderfully plastic-y round buttons of 2006. The app icons come from a variety of backgrounds, including: classic movies, internet communities, Trans pride, and a good ol' smattering of colors. Oh, by the way, did I mention the pandas? Pascal is my favorite mascot of all time. Their expressions are so vivid and clear, I am genuinely filled with joy every time I see them. And the sticker pack is to die for!! Please, play around with this app. I don't use calculators often, but when I do, I choose PCalc..Trilogi62Version: 3.8.8

Lagging terrible latelyI’ve been using this app for years. It’s always been really good. I noticed it lagging on my iPad Pro 2020 and now it’s lagging and freezing up on my iPhone 12 Pro Max. Obviously not a hardware issue so I’m hoping the lagging and freezing is fixed with an update. I’m giving 3 stars as an average. When it works it’s a five star app. Lately it’s less than one star..CwbcpaVersion: 3.10.2

PCalc is wonderful!I’ve used pCalc for years and it always works great. I’ve never had any problem of any sort with it. It is just like using a physical calculator and that makes it easy and natural to use. Get pCalc, you will love it!.Ron CharltonVersion: 3.12.2

Simply the best Calculator applicationI have have used numerous calculators applications. I have also used, and purchased many just ok Calculator applications. Plus bad , or difficult Calculator applications to operate also. Some Calculator applications when updated certain features stoped working correctly. Plus some had no developer support when purchased. Hats off to the software developer for this simple to use, but powerful Calculator application..ShadowWalkerCAVersion: 3.7.6

The first calculator that made me want to learn how to use all of the “weird” buttons.This is the first calculator that made me want to sit down and learn how to use all the functions on calculators that I haven’t had to use since high school. It’s just flat-out beautiful, and deep, and clearly made with care and love. When’s the last time you could say you fell in love with a calculator? I almost forgot, this is one of the most iOS-integrated apps out there. It comes with a fantastic Widget, and the best smart watch calculator app EVER—for any platform, not just WatchOS—thanks to its swipe-up function keys..Steve TsuidaVersion: 3.8.8

Ten keys accessI am using a full size keyboard on my Air. Allowing keyboard to control your program for paid clients would be great. Please make this feature comes true asap. I use Pcalc on very often..Macrohard RejectedVersion: 3.11.3

Sound quirkThe sound should be based on the ringer volume instead of the volume. This isn't a video game application..PLEASE FIX THIS...,,,,,!!!!Version: 3.10.5

Lots of featuresBut it has some functional quirks. Things like hitting ‘C’ does not fully clear the register. So you enter what you think is your next equation and old values are persisting. Maybe the way it is intended to work, but it’s a pain to have to hit ‘AC’ all the time. Then there is portrait mode where ‘C’ flips to ‘AC’ if you accidentally tap it twice. Resulting in your memory values being wiped. And as my fat finger is hovering over the ‘C’, I may not notice it flipped functions. That all being said, a lot of features in this calculator, lots of custom stuff. I’d like ‘ac’ just plain removed from basic calculator views, just give me the bare basics for doing the basics. I can flip to a custom layout when I’m doing heavy stuff..XadurVersion: 3.11

Very customizable!I got it set up just the way I wanted. I’ll never have to look for another calculator app again! Wonderful dev too, offers long continuous support for this amazing app..Jozh45Version: 3.9.5

Excellent Calculator and then some...This app has everything you want and need from a calculator. I have not found a function that I can’t use. I highly recommend this app for all your math and basic calculator and conversion needs. The only issue is some odd thing that happened for the first time today (Apple just updated it’s iOS) after entering values into M+, the calculator displayed “Censored!” Upside down. When I went back into the app I was exactly where I wanted to be and it hasn’t happened again. Fingers are crossed..MRKS-123Version: 3.9.2

Strange...Why did your application displayed « Censored » upside down in the result window? I was just addind and multiplying numbers.Usager très déçuVersion: 3.9.4

It does it all and moreI was hesitant to pay for this app. There is really nothing the app can do. It is completely customizable. App support is top notch. They write back quickly and have been able to help with all my requests/questions. If you do much math for work or pleasure, I highly recommend this app!.PkpsmallVersion: 3.7.4

Je suis comblé, mais...J’utilise cette appli de calculette depuis plus de 3 mois et je dois dire qu’elle surpasse la HP 11C que je m’étais procurée à la fin des années 70 🤫😅... et, même, toutes ces applis que j’ai téléchargées ... je crois bien les avoir toutes essayées ! Certaines étaient vraiment très bien mais celle-ci, je le répète, se démarque en ce qu’elle permet, par exemple, de calculer les taxes de vente en un clic... mais le plus important est que tout se fait de la façon la plus intuitive qui soit ! Mais, bon sang, pourquoi a-t-on oublié le français ?.Alain GagnéVersion: 3.8.9

Great AppWould love to see a custom text inclusion on the tape though to show what is being calculated next to the number instead of below. This would be very useful I. The tape and allow for better understanding and clarity when shared.DFloVersion: 3.8.8

Excellent app, although ...... I pine for the ability to: 1. Share set-ups between devices. 2. Share custom function libraries between devices. 3. Call custom functions from custom functions to leverage code re-use. DRY principle anyone, anyone, Bueller? All said, as RPN enabled calculators go PCALC easily enjoys inclusion in the top 5. Kudos..1e99Version: 3.8.2

Just gotta have itThe pcalc took is a great all around number tool. From simple calculations to the days you miss your TI-whatever whatever. The new notification centre tool is a nice add and with some research there are some nice customized keyboards (thanks Dr Drang).Bill KVersion: 3.3.2

Great scientific calculatorI love having a fully functioning scientific calculator in my pocket. The developer is sooo responsive too. I suggested a 1/x function, explained why it would be a good idea and shortly thereafter it was included in the free version. Then i bought the full version. Worth the $10 to me at least. Thanks a 10 exp6.Larry WilsonVersion: 0

Simply the bestGo ahead and look at that feature list. Is there anything more to say? New to this version is an optional payment for some nice icons. I'll pay a bit for those because I bought this app years ago and have gotten my money's worth, and the developer is super-responsive; he's the kind of developer that I don't mind throwing a few dollars towards..DwharrisonVersion: 3.6.4

This is a great calculator!This is a great calculator which functions not only as a regular or scientific calculator, but as an RPN calculator as well. Although I was not familiar with Reverse Polish Notation, since getting this calculator, I am learning and becoming accustomed to RPN, and find I am starting to prefer this to the regular calculator. Pcalc also includes a large number of conversion factors and is very customizeable to your preferences in appearance and functionality. I am using Pcalc on an iPod Touch and and IPad Mini and have found it is well worth the money..Learning RPNVersion: 2.8

Great calculatorIf you're looking for a simple and beautiful calculator for an iPhone or iPad, this is the one. Don't let the RPN scare you off; you don't have to use it..TewhaVersion: 2.4.1

Best calculator appPCalc is the best calculator app on the iPhone (and the Mac). It's everything you need and the author is very responsive and open to suggestions on how to make it even better..Warder_clVersion: 0

The Ultimate AnswerIf you want to add 1 + 1, the built-in iPhone calculator will do you fine. If you want do the kind of math that matters -- build things, develop things, define things -- then you need a serious calculator for serious work. PCalc is all that and more. Toss your old HP, and let your PCalc for iPhone do your figuring..ReneritchieVersion: 0

A great calculator by a great developerIf you think $10 is expensive for a calculator on iOS, rest assured that PCalc is a great value. The calculator itself is highly functional and super customizable. One of the best things, however, is the developer behind this app, James Thomson. This man never stops - with every update to iOS, he always has updates to incorporate new iOS or iPhone features on day 1. And he doesn't even charge for updates. The man has been developing versions of this app for many years and won't likely stop soon - so you'll definitely get your money's worth if you invest in this app because you'll still be using it years from now. PS: James, what have you done now? ☺️.SupaconVersion: 3.6.4

It's true - The Best CalculatorStill the best calculator. I've been using PCalc for almost 25 years. I've gotten so much value out of it. Love the new icons - happy to send a little tip to the author..Bret BrettersonVersion: 3.6.4

Buy PCalc IMMEDIATELY.PCalc is the most powerful, most flexible and strangely, most entertaining calculator for iOS. If you don’t have it, you need to buy it right now. Trust me. It’s worth every penny and then some. And if you’ve got a Mac, go to the Mac App Store and buy PCalc for OS X. It’s equally amazing. Update: For those complaining about the new icons/tip jar, stop and think about how many times you've been charged for an update. Never. Not once. Yet it keeps getting updated. PCalc is the work of one dedicated man who is doing his best to eke out a living so please, be understanding. Be kind. The tip jar allows you to show your appreciation and help fund future development and, as a thank you, you get access to some nifty icons. I'd say that's a win for all involved. You're under no obligation to tip and you'll still get updates so be happy and enjoy PCalc..G1k0.comVersion: 3.6.4

I don’t even like the new icon...The old icon was way better, IMO, but I’m leaving a 5 star review *just* to help counteract the ridiculous 1 stars for an icon change. It’s also a fantastic app..Bond.Version: 3.5.3

My Go-To CalculatorThere are so many fantastic details and thoughtful touches that have gone into this calculator app, including open-parentheses count, editable layouts, and collapsible Today extension. I use it pretty much every day—worth every penny. Updated review for the latest version: the icon is fine. If you're giving this app one star because you don't like it, well, we can't be friends..Mr MangeloVersion: 3.5.3

Fantastic appThis app is amazing and charles hong is pretty mean to rate it 1 star because he doesn't like the icon. my review of charles: jerky app reviewer. 1 star!.SamsonjsVersion: 3.5.3

Awesome calculatorPcalc is easily the best calculator I've ever used. It is extremely functional, with far more functionality than I will ever need to use. I wish I had it when I was in school! The custom layout option is great, as I've been able to create one with custom buttons and formulas to use exclusively at work, so that I don't have to take the time to generate a spreadsheet. On top of that, the developer is super responsive by email and Twitter, in case you ever need some help. Overall, this is one of the best app experiences I've had on iPhone or iPad, and I can only assume that the Apple TV version is just as excellent. Easiest 5 star rating ever!.SsklassenVersion: 3.5.2

PCalc 3.4.1I don't usually do product reviews, but this app is an exception as it is a great product and any questions about the product is dealt with very promptly by the developer in a professional manner no matter how trivial the question may be . Don't hesitate to buy the full version..Amepro oneVersion: 3.4.1

Happy...for now!Loving the functions. Bring more more more!.NzaksuVersion: 3.3.2

This is the calculator you needPCalc continues to be the best calculator app on iOS. If you've exceeded the abilities of the built-in basic calculator, you need this. It has a wide range of conversions and functions, a lot of great customization for the calculation display and themes, a well-implemented persistent tape, and a whole bunch more stuff. The new features to let you customize the calculator are awesome, but the best is iOS 8 support for putting a little calculator into the notifications screen - so handy, you can even do quick math while your phone is locked, so handy! The author is responsive to feedback, and supports the product very well..CsaldanhaVersion: 3.3

Great calc, great updateThe best calculator gets even better with button and layout customization and a killer iOS 8 notification extension. #perfect.Rs3yyzVersion: 3.3

THE best calculator on the App StoreThe iOS 8 update makes it even better! I now have a PCalc widget in my Notification center so I can start calculating something while in any app (or from the lock screen) and resume that calculation straight from PCalc Also the buttons are now totally customisable, so if you don't like the layout, you can change it to make it your own! And there's a lot of themes, I like that too.Felix LapalmeVersion: 3.3

There is nothing better than this appI purchased more than 10 calculator during past years. So far, I found this calculator fastest and most customizable calculator ever. It deserve a five star..PouyanemVersion: 3.3

Layout Editor!Great app. Love the new layout editor!.302anonVersion: 3.3

Lovely update to a wonderful calculator appThe iOS 7-ready update is absolutely beautiful, and somehow still manages to find interesting new capabilities to add to what is far from a simple calculator app. There's a sense of fun in the design, the whole thing has a distinct personality, and (most importantly) it has a powerful feature set that can be tweaked and customized to your heart's content. I'd be very surprised indeed if you could find something math-related that it doesn't do. If you need something more than a basic calculator, or just value great apps lovingly made by someone who's been at it for a great many years, you should give PCalc a try..PaigelandersVersion: 3.0

The best RPN calculatorI tried so many of the RPN calculator apps…. Then I found PCalc and bought it for my iPhone and for my Mac. I asked the developer if he could add thousands separators to the paper tape for the Mac, and he did in the next revision!.Super BotnikVersion: 2.8

PCalc Negative Reviews

Just like your default calculator! Do not buy!I am disappointed in. Is app. This app was in the App Store for the Apple Watch and I thought it could do the scientific calculations from the Apple Watch but you can’t. You can only do simple math problems with multiplication, addition, subtraction, division and tip calculations, etc,. I thought that it could perform scientific calculations on the watch (since it was in the Apple Watch App Store) but that’s only if you used you iPhone which is stupid because your iPhone can already do that out of the box. I think this app is well overpriced and it doesn’t offer any special features to carry a price tag of $9.99. I wished that I could get my money back. It can’t even do simple currency conversions! It’s just an overpriced calculator app that I’ll never use on my iPhone 10s because I’ll just use the default calculator..Bryan.y.yuVersion: 3.8.8

Difficult to find what your looking for.I own several calculator apps but with this one I can’t seem to get beyond basic function capability. Even after paying $10 for the full version it looks like I paid for just a basic calculator. That means the advanced functions are really not there or to difficult to figure out how to get to. It’s great for doing conversions or using physical constants. However, for any kind of advanced math, I will have to go to my other apps..CelticEddieLVersion: 3.7.7

Users are Supposed to Purchase Multiple TimesI bought PCalc only to discover that some features are still locked behind a paywall, which the developers call "tip jar". I paid a second time, but after having to reinstall my iOS devices, I discovered that there's no restore purchases button, meaning I should pay a third time in order to use everything. In my opinion this is a ripoff. They're using iCloud to sync your "tip", but I don't..--Skybird--Version: 3.10.5

Editable ticker tape needed !Great app but still needs an editable ticker tape so you can go back and replace the cursor at the exact location and correct the digit. Backspace also needs to work with the ticker tape equation and not just with the result. The ticker tape needs to be live. I had the calcSmart as my default calculator app with this extremely useful function. Kind of now regret paying for PCalc :-/.BarhviVersion: 3.10.2
