If you can use it. For whatever reason, I can’t close the full screen pop up for getting the pay version, when I am fine with the free version. I don’t need the other designs. A work around, maybe an X for closing it would be great ### 4/5 — Nice *2025-08-22, version 5.22.10* Good news: It works Bad news: One word: ADS ### 2/5 — NO use to me! *2025-05-14, version 5.22.10* Followed all directions to 1. Put standard /basic view on window (and lock in), and 2. Remove history. I have multiple scientific models I use often. I want my iPad to have a basic version when I just want “1+1=2” and a simple, quick answer. Do you have a way for me to select the basic on this “pro” version? And, to remove the history tracking? Right now, I’m doing this with PENCIL AND PAPER! Low stars is for no OPTION. ### 2/5 — Works but very slow *2025-04-29, version 5.22.10* For a simple calculator app, it takes an unnecessary amount of time to load up and become ready to use. Even during some calculations it seems laggy. Note that this is for the paid version with no ads. It seems to behave as if it is still trying to load the ads but without displaying them. It has caused me enough annoyance that I have now deleted it and use something else. Therefore wasted my money. ### 2/5 — Ads are overwhelming *2024-12-02, version 5.22.7* You can do one or two calculations and then the ads start. They are relentless. The option is to pay over $50 per year to be ad-free. ### 1/5 — Stopped working *2024-11-17, version 5.22.7* I paid for the premium version of this and have been using it for years. It always worked fine. Then it just suddenly stopped working. When I try to open the app it just loads and loads and nothing happens. It’s been like this for weeks now. ### 2/5 — Slowwwwww *2024-11-16, version 5.22.7* I used to love this app, quick click and you have a multifunction calculator. Now after the update, you click on it and wait and wait and wait, it finally comes up incorrectly with enlarged just basic section and you have to tilt the iPad back and forth so the complete calculator comes up. Stopped being a quick calculator and started being an annoyance. You have to wait every time you open it. ### 4/5 — Great app, but slow to load *2024-11-04, version 5.22.7* The paid version I have is a great app. Latest update, however, makes it slow to load…10 seconds or more. ### 1/5 — Used to be fine. Now ads kill it. *2024-11-01, version 5.22.7* I installed this app many years ago and don’t recall the ad experience being soo obnoxious. Obviously the developer has wratcheted up the monetary extraction experience. How much ongoing developement does a calculator app really need or undergo, which would require such an obnoxious ad experience? There are plenty of much less intrusive ad experiences to assist in financing the developer providing a “free” (ad supported) version of the app - this is not it, as it’s waaay over the top in the full screen, intrusive, obnoxious, hijacking ad experiences like at least every minute or two. You had _one_ job - to be a usable calculator app. With the obnoxious ad experience you failed. ### 2/5 — why *2024-10-29, version 5.22.6* it takes over 5 minutes for mine to load and then its super laggy?? ### 1/5 — All advertising *2024-10-28, version 5.22.6* Loved this app for years. Now full page ads. Ads start immediately. Before you can enter anything. Very counterproductive. After years of using I deleted it. ### 3/5 — Too many ads *2024-10-26, version 5.22.6* Wanted to like this app way more then I do but it’s all the ads popping up when I’m trying to work that sent the ranking down ### 1/5 — Avoid! Avoid! Avoid! *2024-09-25, version 5.22.4* Horrific advertisments interrupting your work. This app is the embodiment of sickening greed. Avoid. ### 1/5 — Don’t use, too many ads *2024-09-24, version 5.22.4* It used to work fine but now an ad pops up after every calculation. Deleting this app and will find something without ads. Companies need to realize no one wants to be marketed to every second of every day. ### 1/5 — ads *2024-09-12, version 5.22.3* ads are too disruptive and problematic 😡 ### 1/5 — Intrusive adds that lock the screen *2024-09-04, version 5.22.3* I understand the need to make money, but this is ridiculous when it makes the app unusable! ### 1/5 — Do NOT Buy - It’s a lie *2024-09-02, version 5.22.3* I’ve bought the pro version to have an ad free experience. I still get ads, so they lied to me. ### 1/5 — too many ads *2024-08-28, version 5.22.3* I couldn't even finish one simple calculation without being spammed by ads. i thought I bought the in app purchase but there doesn't seem to be an option to restore it, can't remember though... anyway. just two more weeks and apple brings their calculator for the ipad... glad to get rid of this app.. ### 2/5 — Used to be great… *2024-08-21, version 5.22.3* Use this for a few years now. Recently it has become absolutely inundated with advertising. You cannot access functions until you wait for minutes to look through their game commercials. Do not recommend anymore. ## Most critical reviews (10 lowest-rated) ### 1/5 — App is horrible *2026-08-06, version 5.22.10* Remove ads ### 1/5 — Unusable *2026-08-03, version 5.22.10* App has become unusable in free form - want me to suffer an ad to use the 4-5 times a year I use it, fine. But give me a way back to my adding result after a few seconds - current ad never ends and is never cancelable. ### 1/5 — Really? *2026-01-05, version 5.22.10* A dollar a week to spy on me, no thanks. ### 1/5 — Disappointed *2025-11-20, version 5.22.10* Can’t get into the app at all since the “x” to get into the app is too close to the top of the screen Tap, tap, tap but I still can’t get in. I don’t mind the ads but this is just a way to get you to 99 cents a week. ### 1/5 — Why 17+?! *2025-01-18, version 5.22.8* ?????????????? ### 1/5 — Don’t download *2024-12-31, version 5.22.8* Full of adds. I will delete it now. ### 1/5 — Lousy pop up *2024-12-20, version 5.22.8* Now every time I open the app a lousy and annoying screen pops up asking to me subscribe. For crying out, what I and many people want is a simple calculator app to do basic calculations. I don’t care about skins or any other features. It really is that simple people, no rocket science. Time to loo for another app with no annoying ads. Ut wait a minute, if I remember correctly, I paid extra to remove ads permanently. Now they want us to pay weekly, really? Apple really needs to crack down on apps like this that do not honor what they promise people when they first buy the app. But typically what this unscrupulous developers do is that they discontinue the app and start selling a similar but “improved” version and charging a subscription. Anyway, I’ll copy and paste this review just in case it disappears. ### 1/5 — FORMERLY Decent App, ruined by Ads *2024-12-13, version 5.22.7* If I could rate zero stars, i would have. Purchased Pro years ago, worked quietly and reliably as a CALCULATOR APP should do. An update (which didn't mention ads or anything like it) made it onto the ipad, and now the app is unusuably polluted. They are asking $0.99/WEEK (more than $50 per year) to disable the ads and use skins. Completely insane this is a calculator. Add in the fact that this was an update to a previously paid upgrade - which removed the ads that time around, and this became an immediate uninstall. ### 1/5 — iOS18 - app paid version needs wifi for it to work. *2024-12-03, version 5.22.7* If there is no wifi, this app will not work. The icon just appears with a loading icon spinning. I paid for this app and it won’t work if I am away from wifi. This should not happen. Why does it need wifi to work? There are no ads to load because this is the paid version. Please fix this. Also why is the size of this app 160MB?? That’s too much. Not even games like Plague and Bring it on use this much storage. ### 1/5 — Calculator for iPad *2024-11-23, version 5.22.7* The clear button did not work The second I tried use a ad popped up for some casino game every time and lost the list I was calculating I deleted asap and I won’t pay for the few minutes I tried to use To pop up a stupid ad in seconds while calculating Buffalo game seems more important to you than my satisfaction You can’t calculate when screen go to and stays offering to buy ## Most praised reviews (10 highest-rated) ### 5/5 — Please make this compatible with iPhone *2024-10-08, version 5.22.5* Easily the best calculator app on iPad, I’ve been looking for iPhone but cannot find one as good. ### 5/5 — Calculatrice *2023-12-13, version 5.22.2* Calcul précis avec toute les fonctions mathématiques. Tout pour l’élève du secondaire à l’université. ### 5/5 — Calculator Pro+ *2023-03-29, version 5.22.1* Love this app. I use it all the time for conversion and calculations. Thanx kindly. ### 5/5 — Clear and Legible! *2023-02-14, version 5.22.1* Modern design and easy to use. ### 5/5 — We love this app *2022-10-06, version 5.22.1* My whole family uses this app so much so in the beginning that we went ahead and paid the small fee for the pro version. we use this app almost on a daily basis and wouldn’t dream of using another one thank you for such a basic and easy to use functioning app that is suitable for classwork when needed. A++ ### 5/5 — All The Beauty & Function You’ll Ever Need *2022-05-06* I 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. **Developer response:** Hello!

Best regards, Support Team ### 5/5 — Great calculator app!! *2022-01-15, version 5.21.0* 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. ### 5/5 — Scientific Calculator *2021-09-01, version 5.19.1* Brilliant! No frills, just works. ### 5/5 — Accessibility review/issue with Calculator Pro. *2020-12-12* 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. ### 5/5 — الحاسبه *2020-11-29, version 5.12.0* شكرا لكم على هذا البرنامج ممكن تجبولي هديا عند بيتي المكن الرقه العنوان ٢٦٧ الشارع ١٣ --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
