Calculator Pro+ for iPad Positive Reviews
Full screen ads at the most annoying moment…The app itself is great since Apple does not ship iPads with a calculator for an obscure reason but the ads are way too annoying! They pop at the most annoying moment, like in the middle of entering numbers and take the full screen and you must wait until the end of the ad to continue what you are doing…. Then you continue just to get another full screen ad 2 minutes later. As another user said, why don’t you block the ads to be only banners which do not impede the use of the app? I was ready to buy it and then I got 2 ads in less than a minutes right in the middle of a calculation… guys… seriously… that is a deal killer!.Thi-cotVersion: 5.19.1
Calculator With Ads. LOTS of ads.Yeah, it’s a calculator and has scientific modes and the ability to convert currencies. You have all kinds of nifty backgrounds to choose from. So that’s cool and I would give it a higher rating if I could just leave it at that. But it’s the ads. Yeah, I get it’s a free tool and you gotta pay your developers somehow. Why can’t there just be a perpetual banner at the top or at the bottom? I don’t have issue with the ads themselves, but I DO have issue with each ad taking up the entire screen. I happily use lots of free apps that have some sort of ad banner. But see, I can still *use* the app! Ya’ll are missing the point. I think it’s safe to say all the other users that have complained about the ads aren’t necessarily complaining that the ads exist. It’s how they’re presented and how it hinders the usability and, consequently, users’ satisfaction with the app..SCG421Version: 5.5
ReviewFor those who agree with “too many ads” THERE IS ANOTHER APP that does all functions, currency, scientific, etc. and isolates it’s adds to make the program usable. It is called THE CALCULATOR!!!!. Now Mr. Developer you have competition that has a program that is user friendly but still has adds. If I turn off their adds life is still better. Everyone should avoid this app and go to THE CALCULATOR.
Too many commercials. Will be dropping for something else. Compiling a list of advertisers to let them know we are tired. Or I can pay to NOT see their adds.
Update Apple requested. It is only free if I pay...that is not free. The businesses already pay to show their adds, they should know I can pay to turn their adds off...which means their ad dollars are wasted. The app developer gets paid twice...not fair! Again, I will find another program..WaynetodorichVersion: 5.12.0
Been using a long timeI like the recent "refacing" of the screen .. since an app doesn't 'break' ...hopefully ...{:-)}... [ and I KNOW I am stretching the word 'break' around right there ] a 'facelift' like this is welcome every once in a while. It's not like the " olden" days ...when your Texas instrument style calculator "broke" and you chose a newer model .. there was a little something different about it -- and you could 'feel' in your hands that it was new....GiGi LolobriggettaVersion: 5.1
All The Beauty & Function You’ll Ever NeedI have acquired dozens of calculators over the years, some specializing in 1 specific type of calculation; however my work horse calculator is the pro version of this calculator. It is simple and straightforward features and functions, and allows customization & personalization to make the experience of using the app truly unique, and enjoyable.
Short of having the app resolving your equations for you, without any user input, what more could you ask for?
I Enthusiastically recommend this app for anyone who has regular daily need of a full function Simple/Scientific Calculator, and owns an iPad..Bucky BearVersion: 5.22.1
Accessibility review/issue with Calculator Pro.I am a current accessibility/voiceover user, and I have a current issue that involves a ad not going away, it is very annoying to see that this ad is not going to be going away at all.
I hope that this issue will be fixed in another update as well, also, can you please provide me the email address in case if I ever had any issues just in case please? Hopefully that this issue will be Resolved in no time, as always, thank you for your service and continuing to make this app accessible to those with visual impairments as well..IOS master 2020Version: 5.12.0

If they had more star I would choose every one of them. This app In my opinion is one of the very best app that I have and I hope they continue to be top rate. They truly have put together one of the very best . I give the folks that put this app together a 100% as the best of the best!!!!!!!!.STMMTVersion: 5.0
Too many ads now!I like the app, and have had it for awhile now. But suddenly there are so many ads! Way too many. You're always having to wait for an ad before you can do anything. I'm tempted to give it only one or two stars because of all the ads! I know ads are how they make money, but really? They've suddenly gone way overboard. I settled for three stars simply because the calculator is a good one. But, frankly, I'm tempted to go looking for a different app to replace this one, so I can delete it, because of all the ads..Spirit99999Version: 5.21.0
ReviewThis calculator is amazing but I think it needs more in the trig and calculus side of math for the more advanced people I. The world[unlike 95% of the rest of the world if you know what mean]and in case you don't most people don't know what 1-6 is and when you give them a calculator they just spam random numbers and equations and in case you think I am one of those idiots I am 12 and know trig.

Great calculator app!!This is one of the fews apps that still let you remove ads permanently for just $0.99. Some apps are charging you $5 a month indefinitely which is insane and a money grab that I will never pay. I would like some more calculator themes and functionality though as additional one time add on. However, hands down the best iPad calculator app as long as you pay to remove ads one time..Stephen AustinVersion: 5.21.0
Works for meI live with a mathematician and his graduate student recommended this app. Now I don't use it for high level stuff, it's clearly been designed to do that kind of calculations. But it's great for calculating conversions between temperature systems and such. I use it to calculate the weights of things in the kitchen, anytime I need to make aspect ratio calculations and for figuring out complex bills. It does great. I've used it for years and never experienced a bug. Recommended..Just another serfetteVersion: 5.1

Calculator Pro+ for iPad Negative Reviews
Ads hijack RAM, useless for professionalsI work in homes of clients doing construction and general contracting as well as on industrial job sites bidding big $$ jobs. I installed this calculator on my new iPad mini because I needed something on it to do little bids on this machine when I’m not using my iPad Air. Wow... it is garbage. Locks up after every keystroke because it’s trying to connect to its ad server, plays video ads constantly when connected to WiFi... I get thr need for a banner ad at the bottom that’s static (you did create the app for income, after all), but locking up because it’s priority is fetching ads before functionality of the app itself, where a dev thinks missing inputs from the client is acceptable while loading more ad banners instead of doing this function in the background... the dev obviously isn’t serious about the app and only cares about cranking in as much ad revenue as possible. If I was advertising online and saw my ad on your calculator I’d give my ad agency one chance to remove ads from crap programs like this or I’d fire them because the people who would be relevant customers would never use an app as broken as this, and I’d be wasting my PPI ad dollars on school children and people who didn’t have enough sense to check the App Store for any of the other 50 results for the search term “calculator” and download any other calculator app. At all..Smashie sezVersion: 5.1
Advertisements on this free version are appallingly irritating - do not installI do not recall this app being this bad when I first installed it but over time, it seems to have grown much worse. The developers not only permit ads on the free version but allow ads that totally hijack the application that one cannot close or can only close with difficulty. You spend more time trying to figure out how to close the ads than actually using the calculator. I therefore consider this free version to be a scam and I will not install their paid version with no ads for that reason. Had they provided a free lite version and a more functional paid version, I would have been ready to upgrade this app to a version without ads., had the advertising on the free version been less intrusive and more easily closeable. However, I do not like being bent over in this manner to get me to to pay up for an upgrade, even though the paid version is cheap enough. Either the developers are not monitoring the ads, unlikely, or are actively collaborating to make the advertising to be this annoying in order to sell their paid version
I am surprised that Apple has even allowed the developers to get away with this and am considering a complaint to Apple about this! Would have given 0 stars had I had the ability to do so..StuG1118Version: 5.14.0
No Longer UsableI have used this app for years, and it was one of the first apps I downloaded after getting my first iPad long ago (why Apple iPhones have a native built in Calculator App but the iPad does not makes no sense to me, and I Love all things Apple). The ads before were annoying but the app was still usable. However now there are full screen ads that you cannot immediately exit to use calculator, which is beyond infuriating. I understand when that happens if I choose to watch a video ad while playing a game app in exchange for an in game reward, but being forced to watch a full screen ad video which prevents me from doing some math on the calculator when I need a quick answer is so annoying I immediately looked for an option to upgrade to remove ads (which actually doesn't upgrade THIS app it downloads the paid version [different app, different app icon, same developer]), then I deleted this "free" version. Just do yourself a favor and buy the paid version (which I really like and I paid $0.99 for USD) and don't bother with this "free" version which is no longer useful when you need the calculator to work at that moment..WinsAllotVersion: 5.0
Remember when you could use a calculator to calculate?I have used this app for quite some time. It was great! Need to do some quick math, load the calulator app. Now it is an ad fest. Ads pop up WHILE YOU ARE ENTERING NUMBERS! And then you can not close them. You get to play “find the close button” when the add finally finishes. I understand the desire for revenue. However, you have allowed your app to become unuseable. You told another reviewer that users have a choice. They can pay to use your calculator or accept the adds. You neglected their 3rd option. Delete this app and use a different free one that lets you do simple math. I think I will go with the 3rd option. Shame though, it used to be great.
Thanks for the generic scripted response. As I said, the ads make the app unusable and the solution of “then pay for the ad-free version” would be great except the way you implemented the ads has completely turned me off of your app. There are FAR better calculators out there..A NonamouseVersion: 5.18.0
Really? Prod Manager, think first!I understand the need to make money on apps. I had one of the first 1000 apps back in the day. I have also been a software executive for large and start-up companies. Net, I understand the trade offs. But, to setup an ad delivery methodology that interferes with the basic workflow of your app is not only misdirected but bad business in the medium to long term.
This was a GREAT app once upon a time. Then the ads started. At first they were non obtrusive. The they got a little more annoying. Now, they disrupt the basic workflow.
Example: there is an ad at bottom of the app upon enter. Ok, non intrusive. Pays the bills. But, over time it got worse. Now if I want to add two numbers. It goes like this... tap 2, tap +, wait for full screen ad with audio to run, tap 2, tap = ... result 4.
The app is now useless, embarrassing and promotes errors when running multi step computations. Net, it is now a deleted app.
Look, I don’t mind paying with ads or a one time purchase fee if the functionality is there. But, because of your decisions, you have not only lost my eyeballs on your ads, and\or one time fee, but you have lost my trust. Now, I will go out of my way to avoid your apps...free or otherwise.
I am shocked senior management or you investors condone this reckless approach to product management. Remember my millennial friends, the world is littered with 100’s of former #1 brands that no longer exist..Pooh's DadVersion: 5.5
Bad experience every time...read below before you download!🚨 I bought PREMIUM VERSION. There is NO difference as the ads are still crippling. Developers still give you the static response that it’s only “a minor inconvenience” and suggest upgrading. They have no other answer
✅ Layout is okay. Like the memory feature.
1. ⛔️Constant ad interruption. Wondering if it possible to finish one calculation without being interrupted. Not recommended to use when toggling between other apps either. Minimizing calculator has a similar result to opening app for first time...que new ad interruption...
2. ⛔️ FULL SCREEN ADS. Forced to constantly stop what you are doing and wait. Hopefully you didn’t just click on the ad accidentally as you just happened to be in the middle of a calculation when the full screen ad opened suddenly.
3. ⛔️ADS TOO LONG and often REQUIRE SOME FORM OF INTERACTION BEFORE BEING ABLE TO SKIP. After 5 seconds you can skip, but you have to press the skip button AND then x button to close? 😡 When you want a quick calculation but the percentage of time having to watch ads is significantly GREATER than the time spent actually calculating one number set, you’ve got a problem.
4. ⛔️ Ads come in sets, 8-15 seconds apart.
5. ⛔️ PRO VERSION IS NOT AD FREE.
6. ⛔️ Super slow. I want a calculator. I don’t care if it has skins..Lava glacierVersion: 5.22.1
RidiculousI am completely appalled that Apple allows this App or better yet this company to tarnish Apples great reputation. Now before I delve into details, I have screen shots of this bait and switch practice. I previously purchased the pro version. I uninstalled because I no longer needed it. Today I reinstalled the app. In the App Store , the IPad Pro version is located adjacent to the $.99 app. The one I own is labeled “open.” I click on it and it brings me to the free version. I left the app open, verified the purchase (I have proof from my receipts that I am oh so willing to share) went back to the App Store and selected the $.99 version. I am returned to the un-closed App and then prompted to pay. It’s false advertising and a class action lawsuit should be filed. Before the devs come back with cookie cutter response, I am more then willing to post my screen shots on the Apple forums. Balls in your court, you decide your fate..BlackivarrVersion: 5.6
Have used for years, now uninstallingHave loved this app, but now it has become so ad-packed, it isn’t usable. Ads now take up to 30 seconds to allow you to get an X to click them off, making using this program a long and tedious process. Am uninstalling after years of use, it is so unusable. Three quick calculations took over 5 minutes because of the ad interruptions. In response to the developer comment: saying you are releasing a knowingly buggy version with ads does not instill confidence that if I buy the paid version it will be better. I don’t mind buying apps. But I tend to base purchases on whether the developers have decent apps I can try for free during a trial period. The fact this app has gotten worse tells me the programming is not improving, and suggests money on the paid version would be wasted money..PhynnVersion: 5.1
POP UPHello? What genius believes we would purchase merchandise, by having my use, of a “ really convenient calculator”, immediately blocked not once, but constantly, and interrupting important work we are doing, with a pop up that covers the screen! I for one do not gamble! I do not nor have I played video games, since PAC MAN! I grew up! 99%, of these pop ups are nothing I need? Lastly: repetition is extremely annoying, and I will likely never purchase something I am shown more often than once, in say a week! I hope this helps!
I realize you are not happy. I understand it is free, and I can look elsewhere! I am not sure why the above statement now, in quote, is anything less than a genuine appraisal! My advice is as follows. I am questioning why any, of your advertisers, would not see how my complaint is legitimate. What makes you think blocking my screen is a reasonable manner, to attract, additional business? Why not focus your algorithm, in the background, to collect information showing how fast your users opt out! I doubt your clients are aware the ads are not being well received. Let me know the results should you test my theory.
WCM.DEKCOLBVersion: 5.9.0
Broken Ads and Condescending DevelopersI was considering paying for the full version, but the developers’ responses to all of the (entirely correct) reviews here have convinced me otherwise. The reviews point out that, while everyone understands ads support free apps, the ads here make the app absolutely unusable. The developer’s response is solely and repetitively to say that the ads support the app because it’s free.
“But we understand ads!” say the users. “These ads are a problem because they are ruining the app that they are supposedly supporting our free use of!”
“Ads support the app that you’re lucky not to pay for,” sneer the developers who apparently lack reading comprehension as well as customer service skills.
“If you want an app you can USE,” the developers mean, “pay us actual money. Otherwise we’ll take the disproportionately large per-use ad revenue you generate and YOU’LL take whatever you can get.”
As for me, I am happy to pay for an ad-free app - someone else’s.
To the developers: In case it’s not clear, the problem isn’t ads. It’s YOUR ads. And your attitude. If you respond to this review, do not tell me you’ll take my feedback into account for your future work. I don’t care, and also, you won’t..Sarah JaebVersion: 5.6
Not Worth Enough to PayIf you're thinking about spending real money to remove the ads, do yourself a favor and read some reviews by other people who paid for ad-free on the paid version of the app. They explain how the paid version removes the ad box at the bottom of the screen when using the calculator but doesn't remove that "one" pop-up ad that pops up every time you open the app. It advertises "recommended" apps, meaning other apps by this developer. (To the developer(s): I guess $3 isn't good enough, is it?)
Aside from that, it's an easy to use calculator (when not connected to the internet), and I love the paper skin, but there are many other calculator apps that have way more skins than this and that definitely give you your money's worth..OttoautoVersion: 5.1
ADS ADS ADS!!!!!!!!!I know the creators who made this need money or something but TOO MUCH ADS!!!it has gotten to the point where this app is unusable I get an ad every five seconds it’s that bad and it can’t even do division it just comes up with a random number sometimes half of the time I solve the equations better than the calculator on this this is suppose to be a CALCULATOR it is supposed to be something you go to when you need to answer an equation not this one it spams you with monetization every five seconds another ad and another ad I spent 1 dollar on my gift card I got from my birthday but no the ads but it didn’t even go away just this is useless for heavily reliance on calculators just buy a real one this app is useless I’m deleting this app..NytfcgnrtdhcfnjytmgcfetkyfghmVersion: 5.5
Tired of it...It’s still a problem. As soon as I click the home button for the app a full screen ad for Solitaire takes over the screen, and rather than make the simple and quick division or multiplication I want, I have to wait with smoking ears for the ad to stop. I’m going back to the App Store and see what other calculators are available.
A calculator should be part of the Apple apps included with an iPad or other hardware, rather than some of the other included ones that many of us never use.
Update:
As to the developer’s response to my complaint, certainly most of us realize that “free” apps wouldn’t be available if they couldn’t glean ad income. It’s common sense. The ads shouldn’t present themselves in a manner that can aggravate their potential customers, however. There’s no profit for anyone in that.
Other apps put banner ads at the bottom of the screen where I can respond if one attracts me, yet it in no way stops my calculator endeavor like this app does. I’ve deleted it and installed another, less frustrating one..HafcanadianVersion: 5.16.0
Deceptive Marketing. Shameful.As noted by others here, but not frequently enough, is the fact that buying Calculator “Pro” does not give you an intrusive free app without pop ups. Allegedly, to get that one you must (then) pay for the in app Calculator Pro “+”. And then that, given the track record of this developer (see past reviews), does not convince this user that pop ups and other annoyances to buy other products will be completely gone with the “+” further investment. Is this active deception or just a(nother) language deficiency in understanding and using common English? This developer’s products are now deleted from my devices. Hopefully Apple will listen to its customers and put a decent basic calculator in its upscale iPad models..VioletdudleyVersion: 5.6
App has Become Ad-Ridden Buggy MessI’ve used this calculator app for years and have always enjoyed its simple design and usability. It had ads but they were kept to a unobtrusive banner on the screen.
A while back the app started running a full screen ad when you start-up. Annoying but workable. Then the app interrupted usage at random and frequent intervals to run full screen ads that you must wait 5-10 seconds until you can skip. Very annoying. Now certain ads cause the app to glitch out randomly and the only remedy is to restart and clear cache. I’m done with this app. A quick search of the App Store and I see plenty of other choices.
Honestly, don’t waste your time on this one..TkbowmanVersion: 5.14.0
Disclosure shows user data collection and tracking by Russian companyUsed it for years, despite of the companies flooding you with ads even after you paid for the ad-free pro version.
But now with apples new detailed disclosure of the apps user data collection, tracking and information sales practices, I was surprised to see the amount of user data collected by this company (in Minsk, Belarus) and that it is sold and shared freely with 3rd parties. No functioning opt out, I tried. Their privacy policies state that they ignore ‘no tracking’ requests.
Considering the flood of hacking and ransom attacks originating from that country, I will delete the app and look for one that has more solid privacy protection..BayarndVersion: 5.19.0
Uninstalled in under a minute of using itLook, devs deserve some compensation for their work, so I don’t mind paying a few dollars for apps I need. But if the free version forces full screen ads, auto switches apps to open safari to open an ad in there, making it nearly impossible for me to use it for calculations, I’m not even going to consider buying the paid version. I would have happily paid for the full version if there was simply an unobtrusive ad on the calculator itself, but this app is more ad than it is calculator. I’m not a fan of devs basically annoying you into paying money to get rid of said annoyance. I don’t even know if the app was good or not, the ads literally prevented me from using it..SnarkumVersion: 5.1
Way too many adsWay too many adds that it keeps interrupting. So annoying that I had to delete the app.
=update=
To Apalon Apps, to reply to your response... I understand that you work hard to create something and you should get paid for it if a consumer believes your product deserves to be purchased. But also there are other calculator apps that are free and work just as well as your app does with a lot less ads. As a consumer, I naturally got one of those apps after deleting yours.
I’m ok with getting ads because I’m trading it for not paying money. But as for your app, the amount of ads that I got (more like was bombarded) was unbelievable, so that made me want to write a review. That is all..FairCritiqueVersion: 5.6
Wow. Pretty much unusable because of ads.Holy cow, I don’t think I have ever seen an app that throws up so many ads. I would say it’s a ridiculous amount of ads, but this is so far past ridiculous that you can’t even see the ridiculous point that you passed far behind you.
I hope this company rethinks how they are going about making income. Full page ad popups right in the middle of a calculation? That doesn’t say “We care about our customers”.
I would buy the no-ad version of the app from them, but not after the experience with the horrendous ad supported version. It’s too bad. I wish Apple would just allow the iPhone calculator app to be used on the iPad.
Suggestion for this company: give your customers a good experience with the ad supported version so they want to buy the non-ad supported version. But I suspect you make far more money on the ad supported version since it relentlessly hits you with ads...forever. And get rid of the full page ads. They really aren’t appropriate for a simple calculator app..BoclarkVersion: 5.1
WORST UPDATE EVERI, like many who paid for ad-free, have used and loved this calculator (scientific, especially) for years. However, like others here have mentioned, since the last update the scientific functions are no longer even viewable and the "base" calculator is BEYOND distorted. Perhaps you forgot to test on all but the very latest version of iOS? At any rate, it is utter garbage on iPad Pro (LANDSCAPE) running the last version of iOS 12 prior to 13 (many of us are NOT keen to jump on iOS 13 as we've heard it has many, many issues). I have NO other apps, paid or not, with this type of issue. FIX, AND TEST YOUR UPDATES IN THE FUTURE! Adding new features at the expense of stability is not smart..Jo Jo355Version: 5.7
Just keep addingDo you want a calculator that never completes a function? What’s 12 x 347? Get your answer? What’s 132% of 48? Did you remember to swipe left on the clear button like a real calculator? If not, this app just adds the next numbers you wish to calculate to the previous ones, which is annoying and terrible. The calculator on a windows computer is more intuitive. Deleted from iPad.
Developer response to my review indicates they have never used a calculator before. Do not trust. 2+3 might equal 21😔. It’s all there in my original review: make a calculator that behaves like a real calculator or get off the App Store. Hey hey: this calculator and the App Store: two things that are wastes of time!.ArghonautVersion: 5.7
Recent changes in the advertisements make the app unusableI had been using this app for a while now, and you expect a free app to have advertisements. It is a fair trade for a simple app to have a few ads. They were there and slightly annoying, but now recent changes in the app have made it so the ads actively interfere with getting work done. Pop-ups came first. Now even being forced to watch videos interrupting simple calculations, and the ads pop up while you are typing, which frequently creates unintended click-through. Unworkable and slimy.
So you lose my ad revenue completely for being greedy. Already deleted and moved on..Misha FireVersion: 5.0
Just deleted it :(After using this app for years, I just deleted it because of all the ads.
This was one of the first apps I downloaded when I first got my iPad, years ago (why a basic calculator is not included with iOS, I'll never know...). The app was fine: a basic calculator, no fuss, no muss. I only use it maybe twice a month. But, about 8-12 months ago, they added an ad program. Not small ads, but big, full screen pop-up ads, and constant pop-ups telling me to upgrade. In a calculator app. That is just ridiculous. So, I'm over it. Found another free app in minutes. It has ads, but they are tiny and easily ignored. See ya..Not so happybirdVersion: 5.0
Almost impossible to evaluate the free version.Seriously, it’s a nice calculator app but the free version, supported by ads, can’t even be evaluated because it throws up a full-screen ad literally every several seconds! It’s not only annoying, it actually hampers any kind of meaningful evaluation of the app before deciding to buy it. DO NOT consider using the free version of this app on a regular basis, unless you enjoy having your train of thought and your calculations interrupted FREQUENTLY.
I really was interested in this app and was considering buying it, but there literally is no way I can evaluate it before buying.
Pass..Wayward MorkVersion: 5.22.1
Ad locked inAnd now the hijack is complete. Unity Ads pops up, takes over screen and no way to proceed without answering their question. I refuse. Needs be a way to close screen.
Used to be a great app.
Having ads for “free to use” is not a problem until so pervasive the app isn’t useable. It does guarantee I will NEVER buy the product - NEVER
To have a persistent, non dismissible ad even worse. I don’t buy games. My age is totally NOT relevant to my using a calculator and I will NEVER answer, just close the app andgrab my iphone.
Sorry but this is not justifiable, just totally annoying. Thanks for ruining a formerly great app.
Zero stars if I could.
But thank you for your canned response. I was hoping maybe you didn’t know someone was ruining your app, apparently you don’t care as long as making money.
Update: response from developer makes it very clear, as long as it is free they can inflict any amount of annoyance - SAD.
Makes me want want to trust the paid app..MakanamaikalaniVersion: 5.14.0
Annoying Full Page AdsJust deleted this app after using it for some time. When I first got the app a couple years ago, the small ribbon ads at the bottom of the screen were intrusive but did not compromise functionality. Now the app pops up full screen ads in Safari for sketchy offers in exchange for personal information. Even after going back to the calculator screen it continues to pop up new Safari screens. It looks like you have to wait until something times out in the calculator app before you can use it without new pop-ups. This app has now timed out with my patience!.IPhannahPiVersion: 5.1
ADS!It is a great calculator and goes beyond expectations but there is one problem, ads. You can’t do anything without an ad here or there. I tried to do 3 problems, that were 1 step, and I have 2 ads. While they are short, most last 5-10 seconds. Another problem about the ads is that EVERY time I log into the app, I have to watch and add. Like I mentioned earlier, you get adds doing simple problems a lot. Sometimes I would get an add in the middle of doing a problem. Great calculator, terrible app..GufhskvnVersion: 5.22.1
You took away everything that usedYou took away everything that made this app great all the different conversions I used them and now I’m going to have to look for another stupid app unless you add them back.
I went to add this to my new iPad 11 pro and everything I loved about it was gone
So unless you add all the different conversations back I’m going to do a way with this app because my phone has a calculator
Why in the world would you downgrade your calculator app I used to use it when I was measuring weight for food and Fahrenheit to Celsius and different measurements you really disappointed me 😡.Rio767Version: 5.7
Not worth the ads...Just keep shopping because this app will drive you mad. Seriously, there are absolutely free calculators that don’t have ads in the store. I was willing to play along with the pop up ads for years until they became videos and took up the whole screen. Devs: please don’t respond with, “consider buying the app to avoid the ads,” because you just went too far. It is insulting to offer a worthless free version (that you are still making ad dollars off of) all in an effort to frustrate the user into purchasing your paid app. I just jumped ship to an actual free app and love it..Sigmaphi465Version: 5.1
Calculations the worstEvery time I open the app and start entering my figures I have to wait for the ad to finish. When I enter whole numbers it won’t calculate until I either enter the .00 or tap the = sign twice. I have considered getting the full version but I don’t know if it will have the calculations of whole numbers or if I will have the same problem. I use the free version on both of my iPads and it is the same problem on both. I need to know if it’s worth paying for the full version if the free version doesn’t calculate correctly..Tonya1007Version: 5.22.1
Ads and more adsI installed this app years ago and recently it’s become utterly infested with ads. I opened it to do some quick math. Before I could use it I had to sit through a 30 second unskippable ad. I then entered 4 of the numbers and was prompted with another full screen ad before even 60 seconds passed. How is this usable? I understand ad revenue as a means to pay for things, but this is ads to the point that it’s an Ad application with an included calculator. I’m honestly considering reporting this to Apple as an abuse of their in-app ad system..RathgoodVersion: 5.19.0
Don’t bother to downloadThis formerly was a great calculator. Way back when I first got it, I got the “Pro” version because it “supposedly” was free of ads. Then little ads along the bottom started creeping in. I was still OK with it, but now, every time you go to use it, a FULL PAGE ad covers the whole calculator and you have to wait for the little video to play before the “X” appears allowing you to close the add. Totally frustrating! I’m deleting it and looking for a different calculator app. I’m not paying them AGAIN for a supposedly ad-free app, because that is what I did the first time I downloaded this app!.Doc BohVersion: 5.1
Unusable Due to AdsWhen I first downloaded this app in 2017 I believe, it wasn’t so ad crazy. Now, you can barely do one calculation without it ads popping up. Not only does it have full page ads that stop you from using the app, but they have sounds that accompany them. It’s definitely unusable if you’re trying to use it in a class or work type setting. I understand that they have a paid version of this app, and that’s fine. However, they should get rid of the free version because it’s impossible to use..ResillientraysVersion: 5.19.0
The Ads have rendered this uselessThis used to be a good app, however the addition of random full screen ads in addition to a permanent banner on the bottom has made this app useless. More than once I have lost work I was doing when the app just flipped into a full screen ad for some random app and the only way to exit is a tiny x that is hidden in the background in the top right.
Additionally, the banner at the bottom has been sped up so that is distracting and an irritant, As in it is a trigger for headaches if I use the app to long..Noyb1Version: 5.7
Find another optionI had this app installed for all of five minutes. The constantly rotating ads in a bright banner against a dark background were the most distracting and user-experience unfriendly thing I have seen in a long time. I don't know who designed this app but they could not have made it clearer that they were more interested in monetizing the service than they were in making it usable, because as far as I was concerned they might as well have been screaming in my ear the whole time I used it. Avoid; there are better apps out there..FenbeastVersion: 5.5
Monetizing ruins itI started with the free version of this app and thought it was a good humble app, then I paid for the pro version a while back and have it installed on several devices. Now they want me to pay again for a “new” pro version to get rid of the ads which have been added back in, and have pushed out a lot of monetizing crap (watch an advert to get a skin). I paid once, where is product loyalty to me?? Where is the restore purchases option? I would rather get another calculator app knowing it has ads, than be treated this way by some corp-rat hijacking a decent app..ScroobiousVersion: 5.5
ScamShoves ads in your face full page ones right when your typing in your numbers then it messes up your calculations or you have too start over.. devs don’t care the review
S are all bought look at the negative ones there the truth and it will shove ads in your face after your done too let’s get this off the App Store she,e in you devs oh and the updates are. Lie it’s just to update the sponsors aka new ads. Let’s flag this get this off the store I’ve had enough sure small ads at the bottom not when I’m doing ,y bank numbers and you blatantly mess that up.GodasmywitnessVersion: 5.12.0

Abandoned After Years of UseAfter updating to version 5.22.1, the app now forces the user to view 30 second ads at approximately one or two minute intervals. This renders the app essentially unusable. NOT RECOMMENDED!.DigitalDukeVersion: 5.22.1

Totally Useless!Look, I understand that we have to expect Ads with the free version of the App but this crap is now useless and unusable unless you “pay”. In addition to ads appearing at the bottom of the screen on every calculator screen, you now forced to watch 30 to 45 second full screen ads (which you cannot close…) before EVERY SINGLE calculation. Stupidity to the extreme. App to be deleted..MontrealbuddyVersion: 5.21.0

In your face adsWas a long time user of this app until they decided to throw up a full page ad when trying to use the calculator. What’s worse some of these ads are hard o get rid off.

NOW Too many adsI have been using this app for over 10 years. It was good. NOW there are too many ads. After one calculation, an ad pops up. The ad lasts for more than 30 seconds. Then you do another calculation, another ad pops up. Sometimes there are 2 ads after one calculation.
It is really annoying that there are so endless ads when you need to a bit calculation. I won’t recommend this app..CC MyraVersion: 5.22.1
Ads now making unusable.I used this for years and was super happy with it, but recently the volume of ads seems to have increased recently to where it's unusable. I just tried to do a very basic quick calculation(splitting a grocery bill into three!) and I got six ads during the short time it took, because the third one was so abrupt and unexpected that I had to start over. Once I pushed two buttons and another loud, full volume ad popped up. I used to get one, maybe two, which was fine and to be expected, but this is ridiculous..Spookycookie88Version: 5.22.1
