Otherwise great app. Best scientific calculator on iPhone. ### 3/5 — Not working *2017-10-28, version 1.2* Doesn’t work on my iPhone 7 with iOS 11.0.3. The numbers are invisible on the display area. ### 4/5 — Great but... *2017-04-04, version 1.1* It's reported to die within next major iOS update 🙁 ### 5/5 — Great calculator *2016-08-22, version 1.1* Beautifully set up. Easy to use. ### 5/5 — Brilliant *2016-05-30, version 1.1* Does exactly what it's supposed to, nearly as good as a real calculator. Couldn't be any happier with this app! Perfect for Trigonometry ### 5/5 — Great!!! *2016-02-01* This is exactly what I needed to do my homework !! ### 5/5 — Best *2016-01-30* Best scientific calculator for everyday usage on iPad or iPhone. ### 4/5 — FIX SHRUNKEN VIEW *2015-08-31* Then, all will be perfect ### 5/5 — Unfortunately broken by iOS 8.3 *2015-05-18* Love this calculator, but unfortunately frequently opens up shrunken to half size in each dimension under iOS 8.3. I hope Joe comes back to fix it! ### 2/5 — What Happened???!!!!!! *2015-04-29* This was my favorite calculator app. Now, since the update to iOS 8.3, every time I access the app it shrinks to half the size in the center of the screen. What gives????!!!!!!! ### 5/5 — Why!!! I just found this application *2015-03-18* This app is very usefull. if I had found this when I was a engineering student, I would not buy a calculator 😁😁😁😁😁😁 ### 5/5 — Brilliant yet simple; flexible snd intuitive *2014-12-21, version 1.1* A good all-round scientific calculator ## Most critical reviews (10 lowest-rated) ### 1/5 — It does not have x and does not have fractions *2025-08-21* 1 star ### 1/5 — Does not work *2018-02-16, version 1.2* 2018 - just frozen. ### 1/5 — Display is unreadable *2017-10-07* I have a gray band across the top of my iPhone 5s and iOS 11.0.1, that when I enter numbers I can see the cursor move but can NOT read any numbers on the display. Kinda hard to read the calculator ‘s answer. ### 1/5 — Won’t work *2017-10-01, version 1.2* Cannot contact the developer. So must post this review. The screen is grey with ghostly a “deg” and some other symbol appearing on the left but nothing you type in appears on the screen. The cursor moves but nothing else appears. I have an iPhone 5 with the latest IOS 11.0.1 update. So at the moment it’s a useless calculator ### 1/5 — There's no X *2017-05-09* I looked everywhere and there is no X, I can't do any of my algebraic equations for math without X ### 1/5 — Shrunken if your not upgraded to the newest iOS *2015-10-30* Looks like a great app, but I can't use it because I didn't update my iPhone and for operational reasons, I won't. I know it's my problem, but if you're not upgraded, don't get this app. ### 1/5 — Stopped working *2015-05-05, version 1.1* Worked fine for a long time, now for months it goes tiny on the screen upon opening and can't even click buttons. Developer hasn't fixed in a long time. Unhappy. ### 1/5 — Bad *2013-11-10, version 1.0.3* Crashes at opening ### 1/5 — Crap *2013-10-06, version 1.0.3* Doesn't open ### 2/5 — Scientific calculator *2017-12-06* Simply does not work No access to developer ## Most praised reviews (10 highest-rated) ### 5/5 — FREE and Effecient *2018-01-14* This is a good replacement for the calculator installed on the iPhone/iTouch. I have it installed on my iPad Mini too and have used it a lot for Math, Chemistry, Physics, and Accounting. Love the Clacky sound effect when pressing digits and shortcuts to inverses. 5⭐️'s because of its performance and free distribution. It does not crash. This app does not endorse extra money to remove ads or access all its functions. It is made fair and love this calculator. ### 5/5 — So simple and absolutely useful. *2017-10-19, version 1.2* It's got me out of trouble many times. I'm glad it's sticking around. ### 5/5 — Welcome back ! *2017-09-27, version 1.2* It’s great to have the app newly updated for iOS 11 as I was missing it and it’s still the best scientific calculator for my needs. Well done ! ### 5/5 — Awesome *2017-08-02, version 1.1* 👍👍👍 ### 5/5 — Excellent *2017-07-17* Scientific calculator for people that miss the FX-82! ### 5/5 — Wonderful but... *2017-05-13* There hasn't been an update since 2013 and it could probably use one. Maybe add themes and key customization also. But get calculator app none the less! ### 5/5 — Awesome *2017-03-21* It does fractions, it reduces radicals, and it gives Trig answers in simplest radical form. Enough said! ### 5/5 — Excellent calculator app *2017-03-13, version 1.1* Easy to use, love that it can display answers in surd form. ### 5/5 — Wayyy better than the calculator app bundled with iOS *2016-10-17, version 1.1* Works with inverse sin - perfect for an a level maths student! ### 5/5 — Great :-) *2016-10-12, version 1.1* Proper job! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
