HP 12C Platinum Calculator Positive Reviews

Works great with iOS 11 (October 2017)As of October 21, 2017 this app works great in iOS 11. Given that HP is now using a cheap low cost provider to make the new physical calculators out of Asia, this app is the only HP12c worth buying. The new physical calculators don’t register half the keys if you type fast. This app is great for iPhones and iPads. Make sure you get the platinum version in order to have the latest features such as backspace..Awesome Coffee AppVersion: 2.2.7

Updated version works greatI’ve only used it a few hours and it works as expected. Mimics my physical 12c platinum. Kinda pricey but it’s an expense as I use it for work. iPad version is huge! Would like documentation on tips functions. Figured it out but it would be useful if there is a help function (besides the flip help on the back).MmarcottVersion: 2.3.4

HP 12c. Very satisfiedI just downloaded the app and it works fine. I was able to lower the volume on the keys. It flipped to horizontal quickly. It has nice new features like Undo if you clear a number by mistake. It has back space so you can correct a number. It also has a built in quick start manual for new users or if you forget how to input something. It's really great to have an HP in your pocket. Very satisfied..Markp20Version: 1.0

ExcellentSix years ago I wrote a review and gave it one star because of some math inconsistencies that were also at odds with the way the real 12CP worked (I still have two of them). I had honestly forgotten about this review. I revisited the app and now give it 5 stars. It seems to now work like the hardware version in everything I checked. This is as good as it gets..OTERRYAVersion: 2.2.7

Smooth, Bug-free, FastI’m a huge fan of these calculators and bought this one so that I’d have access to it anywhere. So far it’s been perfect. No issues whatsoever. Works great, looks great, and it starts up extremely fast. I also love that the mobile version has the portrait mode and the “tip” functions..Muffinman720Version: 2.3.3

Love it but fix the crash bugI’ve used the app for years and love it. I really like that it’s 2 calculators in 1, depending on if your phone is in portrait or landscape mode. The last update introduced a bug that crashes the app. Workaround is to click on menu in the horizontal/financial calculator screen then reset. Please fix this extremely annoying bug! Would rate a 5 if this bug was fixed..BigPullVersion: 2.3.3

Please update the app to a 64-bit architecture!I use the HP12c Platinum calculator app almost everyday for years now. I sincerely hope HP will update it to a 64-bit architecture so that we, loyal and satisfied customers, will be able to continue enjoying this app in future versions of iOS! Please update it, please!.AfaboyVersion: 1.0

The Original!Nothing beats having the original calculator for IOS, from the original source. Now if only HP would complete the collection by publishing the HP-16C!.Mac.pro.userVersion: 2.3.4

Great AppI love this 12cp app and it's my primary calculator. One big problem, on my iPhone 13 Pro Max the CLS button crashes to app in either hoz or vert positioning. Strange as I also have the 15c and it's OK..47AbbottVersion: 2.3.4

Little bit expensiveGood app when you are used to RPN financial calculator but expensive for that. The key click doesn’t work on I7+. Key vibration is annoying They should add key haptic return option.Alan_blackVersion: 2.2.7

Whats not to love?With the latest updates, the bugs that people complained about are gone. This is app is the next best thing to the real deal..Sea-dweller1Version: 2.2.7

Works great on iPADOS 13.4If you open the app, and then first press MENU and then RESET to clear all of the registers, the app works fine and does not crash when CLX is pressed..RogoBogoVersion: 2.3.3

Hp 12C platinum app on iPhone 11I’ve used the 12c for almost 40 years. With this iPhone app, if I press CLX to clear the number from the x register, the whole app quits and closes. This is very frustrating. Why is this bug in the app?.SanantoniosamVersion: 2.3.3

CLX key issueI love the app as a replacement of my old 12C. But, when ever I press the Clear function ( in rpg) in either landscape or portrait mode, the app closes..Strongman9031Version: 2.3.4

No updatesWhat about update this App to retina and 4 inch display!? For 14,99 dollars it would have more support. Disappointed..LeocoraciniVersion: 1.0

Needs updateI use this app on a daily basis, and it work on iOS11, it needs to be updated by the developers. Please update it so we can keep using a product we paid for..OzirisVersion: 1.0

OkayNothing spectacular, I would agree that the resolution should be better. -4 squared is not -16, so a few bugs. Financial calculations appear to work. A little pricey and should be updated..AdamD1979Version: 1.0

Update: works finallyUpdate: 2019-02-12 I think a lot of people, myself included, have given up on this app and removed it from their iOS devices, hence the lingering bad reviews. Low and behold, HP actually updated the app, and it works, just like the actual calculator. I am not giving it 5 stars because it is not optimized for the iPhone X (the bottom part is partially blocked), and there is no explanation of how tips work when in portrait mode. —————————————————- As of today (May 2013) there has been no update, no retina display support. So buy it only if you really NEED the original 12C, otherwise there are plenty out there with a nicer UI and work just as we'll..Barnaby416Version: 2.2.7

Worth the moneyI had been using the clone of this calculator, available here also, for quite some time. It was very good but it isn't this calculator. This one is the real thing. Vertical it is a normal calculator with a tip function that you will hardly if ever use. Turn horizontal it is the HP 12C. A familiar and useful friend. Touch the hp logo and it flips for an instant cheat sheet. Press menu and an abbreviated manual is available. I found it hard to read the key sequences but it is enough. Simply: There is no substitute. Buy this one..BbfolgartVersion: 0

Awsome. Plainly the best hp has.This app is not just another app. When I put it in landscape it has all the functionality that my regular 12c has. All calculations are exactly what the real calculator does. I recommend this to all who want or need a financial calculator and at $19.99 it's still $130 cheaper than the real thing..TjaxiphoneVersion: 0

HP 12C Platinum Calculator Negative Reviews

New version problemI use the app regularly. Following the last revision, the app will sporadically error out to the home screen when you hit clearX. Please bring back a version that runs consistently! ** The problem is caused by the load state at startup. If you turn that off, it works but you have to select all or rpn each time..Ygor144Version: 2.3.3

Embarrassing! Calculation errors!?Hewlett Packard has a loyal following and a reputation for highest quality - and for correcting problems when they arise. (Early HP scientific calculators actually were recalled and replaced when a tiny bug was discovered.) But a business calculator that makes elementary-school math errors (e.g., in squaring a negative number) is unforgiveable! The calculator on which this app is based goes back to 1981, and among financial wizards both old and young, it is still the gold (well, platinum) standard! This iPhone version appears to have been introduced in 2009, which should have allowed HP plenty of time to get it working credibly under OS 3.1 or later..Education Technology ReviewVersion: 1.0

Do not waste your timeThis specific developer has not been able to update this App to function within the last 4 years of iOS updates. Prior to that it worked great, just like my actual HP 12-c. During the last 5 years approximately I have reinstalled the updated versions and they ALL crash during financial calculations ALWAYS. Today I tried again and still crashes. Developer needs to take this App down or get it working. This is not a rare issue..NNTPazVersion: 2.3.4

ANNOYING Clicking SoundThere is an ANNOYING clicking sound every time a key is touched. Usually there is a way to turn off the clicking sound through the program. It is not user friendly to have to turn off the entire sound of the iPhone device just to stop the annoying clicking sound. VERY IRRITATING. I would not recommend this product until they fix the sound issues. I hate the clicking sound. I love the HP12C handheld calculator that I have. I HATE the iPhone HP 12C..PerpetuamnmVersion: 1.0

Really HP?!This app was supposedly created by HP. I would love to use my phone and/or iPad with the 12C app rather than have to carry around a separate calculator. Whenever I open the app, it immediately crashes. Then again, then again. Usually after the second or third launch, the app will actually work. It’s incredibly frustrating and it makes the user look incompetent in front of a client. The 12C is a professional tool and it needs to function properly..FranklinSaysVersion: 2.3.3

Don’t waste your moneyI purchased the “platinum version” of hp12c when the regular version quit working on my iPhone. Platinum also doesn’t work. Called HP technical support and a “technician “ in Bangladesh answered who had no idea what I was talking about. I asked to speak to someone in the U.S., was put on hold for 30-seconds & then the same person picked up with the same greeting I received originally. Very frustrating interaction with a company that I once respected..FormerHPfanVersion: 2.2.7

Latest Update FlawedThe iOS 11 update 2 years ago was fine. After the last update it crashes the app when hitting Clear and has too many Errors compared to real 12C calculator when running time value of money calculations. I wouldn’t purchase until they fix these issues..KPH KPHVersion: 2.3.3

I trusted HP -- BIG MISTAKEMy old HP12c emulator app was dated and the 3rd party developer was no longer supporting it. I thought that I would be safe if I went with the HP app, because even though it was expensive, I thought that as a reputable company, they would keep it up to date. That was a big mistake. THIS APP WILL NOT WORK UNDER IOS 11. It is not that it doesn't use IOS 11 features. It will not run at all. So for its high price, I got a month of functionality..JFGtechVersion: 1.0

This app needs updatingThe app worked fine for awhile, but now the finance calculation doesn’t work. I have to delete the app and then reinstall it if I need the finance application. I wish I had my money back. The aggravation is not worth what I paid, disappointing to say the least. Now I have to carry the actual calculator everywhere to avoid the reinstalling. There should be a fix for this!.RE FinanceVersion: 2.3.3

App doesn’t work for basic financial calculationsThis app worked exactly the same as my 12C, but it now errors doing basic PV, FV, etc. I haven’t attempted to do cash flow since this happened but I definitely wouldn’t trust it if it did. It also closes randomly when you click the clear button. Useless, deleted until they fix it. Don’t even consider purchase before then..Damon ColusciVersion: 2.3.3

Full of BugsThis app is completely awful. As others have pointed out it is full of bugs. It is not possible to use the advanced features and options, because pressing the menu key causes the app to irreversibly freeze. The only way to overcome the freeze is to hard close the app and reopen it, thereby losing all of your data. Tremendous disappointment and total ripoff..Tcat2345Version: 1.0

Beware it does not work*Tip - Hit Menu>Reset before every new calculation and it seems to eliminate the error 5 messages in amortization calcs* Listen to the reviews. Hard to believe that HP would release such an embarrassment. But they did. It is not operator error by the reviewers. HP12C users generally know what they are doing on the handheld model and that’s why they specifically bought this app. Total fail and waste of money..DsmithrevVersion: 2.3.3

Works sometimes...This calculator would work all the time. But now over the past 6-12 months it works off and on. I use it for work and it’s starting to irritate me. I wish they could fix it once and for all!.Kyle UtheVersion: 2.3.3

UnusableThis app worked fine when in bought it, but lately It ALWAYS crashes before I finish a calculation. I need this calculator for my job and keep my actual calculator at my desk. I paid for this app to always have with me in the field and has been unusable lately. If this doesn’t get remedied soon I will ask for a refund..Moses1301Version: 2.3.3

Not supported by Apple updatesI’ve been using this calculator for over 30 years in different versions. Do not buy this app the developer has not upgraded it to work with the latest operating system for the iPad or iPhone. The Calculator no longer works! Upgrade this product or put a disclosure out that is no longer a viable product for Apple applications.Shuttled CFIVersion: 1.0

Constantly CrashesI bought this app when I had an iPhone 7 and it worked fine. As soon as I upgraded to the iPhone 10 it started crashing any time I hit the clear button or tried to do a future value calculation. These same problems have persisted now that I’ve upgraded to an iPhone 11. I would caution users to avoid this app..OberwanVersion: 2.3.3

App keeps crashing!I used to love having this app on my phone! Handy when I didn’t have my physical calculator. But for some time now after doing a PV/FV/PMT calculation then next time I try do a calculation the app just closed! I can’t clear the registry, the app just crashes when I hit CLX. I then need to uninstall and reinstall the app to do a single calculation..LylemaasdorpVersion: 2.3.4

Application does not work and needs to be deleted and re downloadedGrew up using this calculator. It worked great for a year but no longer works on my new iphone. Very difficult to get in touch with support. Would not recommend paying the money for this app. Unfortunate, but I guess I have to find a new calculator..Zach 001Version: 2.3.3

Extremely disappointing.Wrote a previous review but want to add to it. This app is so bad, I will never buy a Hewlett-Packard product ever again including computers etc. I wrote a previous review about this product and no one contacted me or anything else. And obviously since they don't continuously update the product they don't care whether it works or not..IcisteveVersion: 1.0

HP12C Platinum app not working with iPhone or iPad nowAfter updating my iPhone and iPad to iOS 14 the app does not work for basic payment calculations and the app closes randomly. I’ve owned both the 12C and the 12C Platinum physical calculators in the past and I am now forced to use someone else’s app. HP please update your app!.DjsymonsVersion: 2.3.3

App Continually CrashesI have used this app for years. This app is not being properly updated by the developer; this product crashes when making amortization calculations. My iPhone VR and now 12 have experienced the same issues; the developer’s web site does not provide support or even an option for communication relating to this app. Assuming there are compatibility issues relating to an Apple update that was never addressed. I have tried everything from reinstalling the app It used to be good!.JaslennonVersion: 2.3.4

Works for the most part, but pressing the “CLX” button causes app to closeIf you are looking for a faithful visual facsimile of the actual 12C Platinum, then this should appeal to your eyes. Unfortunately, if you are also looking for a faithful reproduction of the calculator itself, you will likely be disappointed..814973Version: 2.3.3

Bug / calculator closesI’ve been having issues with this calculator for a long time. As soon as I click CLX the calculator exits to the background. I cannot use this function. I’ve deleted and reinstalled the app, but the issue persists. I got a new phone, same issue..Rick.AlmeidaVersion: 2.3.4

Does not work (freezes at menu button)This app used to be great, but now it freezes when going into landscape mode and trying to hit the menu button. As everyone else pointed out, the obnoxious click noises are a non starter for me. HP, please, for the love of God, fix this app so I don't feel like I totally wasted my money..OneluckyjoshVersion: 1.0

Terrible!!Errors when trying to calculate a mortgage payment. Emulation does not work like the financial calculator. Yes, I compared it to my HP12C Platinum. It would have been nice to also have a working app on my phone. Don’t spend money on this app. I am very disappointed and dissatisfied..Cleanmac1966Version: 2.3.4

Hp 12CP platinumI have been using an Hp 12C for 25 years. I was excited to download the calculator to my phone. I’ve only had the app a few days but it is glitchy as heck. I can’t calculate anything without it closing out of the app. I’ve uninstalled the app and reinstalled and that doesn’t seem to fix the problem..WaldoutahVersion: 2.3.3

So dissapointing - replicas are better.Use HP12c daily. Was willing to pay HP a premium for their product as opposed to a copy. However, although this version says it's compatible, the restitution looks very poor and image doesn't even use entire screen. Lastly option menu won't open. Waisted money..Default User 99Version: 1.0

Stopped workingI have had this app for years. Worked fine. Now it stopped working recently w iOS and is worthless until they fix the bug. Completely unusable right now. Crashes every time..XxxxxxxxxxxxkkkkkkkkkkVersion: 2.3.3

Calculations are wrong. App crashes.Worst app money can buy. It is a shame on HP to rob people by selling this app. Apple should ban this app for misguiding people to buy them. Especially when a calculator cannot calculate right and also crashes when you press clear..Srini3000Version: 2.3.4

GlitchDroid version worked much better, this version has a glitch that makes it restart when you hit clear and you have to reset it over and over..K from GAVersion: 2.3.4

Hp12cI use this app almost daily. The PMT function doesn’t work anymore, returning an error message. I’ve been using one for a decade, so it’s not user error. Likewise now my CLX clear button closes out of the app. Can’t believe I paid for these bugs and no version upgrade in sight. Get on it HP!.Kjh4000Version: 2.3.3

UnusableIt keeps crashing on every attempt to use it, therefore is unusable. I have an iPhone 12 running an iOS 15.4.1. In previous iOS versions it was unusable too. Besides, there is nowhere to find support. In a nutshell, this app it’s a DO NOT BUY..Alvaro10MoraVersion: 2.3.4

Seriously? I have to buy the app again to get a 64bit app? What an absolute ripoff! Boo HPI’m shocked at the absolute egregious behavior of HP. They don’t update the app - then offer a new version that is updated that requires new purchase. This app is the most expensive app I’ve ever purchased. I’m sure not going to buy it again.Aebb1Version: 1.0

Won’t Launch ?!Stopped working after latest iOS update. Refund please..Bobby416905Version: 2.3.3

Cassander1This app has stopped working - perhaps HP could respond to tell us when the ETA is to get this fixed?.Cassander12Version: 2.3.3

Won’t launchAbsolutely no good please refund!.FLYWIREVersion: 2.3.4

Extremely disappointed!I used to use this app all the time. I paid for ir and it stopped working completely. No refund. No response from the developers. No updates to make it work again. They have other apps for sale. Is anyone fool enough to buy them? It feels like I’ve been robbed like all other users who posted their disappointment here. This app should be removed from the app store..MlgondimVersion: 2.3.4

What’s with this irresponsible developer?This app is NOT free. It’s been crashing spontaneously across the user spectrum. Apple should insist on a fix or remove the app, refund the users, and sue the developer.Dr. BrianVersion: 2.3.4

Same issue as other mention…CLXThe app crashes when CLX is clicked. Not sure if it is compatible with iPhone 12 Pro Max..AndyTorVersion: 2.3.4

Do not buy/nor upgradeWhen pressing CLX the app crashes. Waste of money..Tgr64Version: 2.3.4

Update doesn’t work.I just updated the last version and now the Apps doesn’t work. It doesn’t open the calculator. I can’t understand how a company such as HP releases an update that doesn’t work. Will never buy something from HP again. Since I purchased this App it newer works well and HP never fixed the problems. Any new update is a nightmare. This product is defective since the beginning. Suggestion to preserve the good name of the company. Discontinue this product from the Apple store and allow the people that paid for this product to download the HP 12 C standard version free of charge..RacineeVersion: 2.3.3

Stopped working after latest iOS updateO longer working.Gab85timaiVersion: 2.3.3

Last iOS update made it in usableSeveral bugs cropped up after the last update, prior to that the app was good ... hopefully hp will update it ... been 3months now so not holding my breath ... they probably want us to just purchase another version... good thing I still have the physical one that neither Apple nor HP can’t break with “updates”.TravelingPandaVersion: 2.3.3

MrIt functions but the keys are very hard to read (and I'm young with good eyesight!) because they haven't bothered to update the app for retina display. For the price they charge, you'd think they can solve this easy problem--which lead me to conclude that they don't care. And do you really want to purchase a product that is manufactured carelessly?.MzxcvbVersion: 1.0
