I didn’t use anything else. Now I have to sit through a full screen video advertisement almost every time I swipe back into the calculator to enter another figure. It’s frustrating and turns a quick task into a much more lengthy and tedious task. Will delete from my phone if the full screen video advertisements aren’t removed. ### 4/5 — Was my go to calculator *2020-11-20, version 2.3* This was my go to calculator but not operational in iOS 14.2. ### 2/5 — Basic functions with a bunch of unusable teasers *2019-01-26, version 2.3* Try other ones they’re free and have more functions ### 5/5 — Brilliant *2017-08-30, version 2.3* Should put this on my iPhone best calc I've ever used ### 5/5 — Great *2017-08-29, version 2.3* Very nice like all 3 parts tip loan and Regular calculator ### 5/5 — Best ad free calculator for a tablet. *2017-08-28, version 2.3* This does it all.

Disappointing app ### 1/5 — Doesn't have 10^x?? *2013-12-20, version 2.2.1* You cannot market a calculator as "scientific" if it lacks the antilog function. ### 1/5 — Dr *2013-04-02, version 1.8* Worthless, functions are not available unless you pay. ## Most praised reviews (10 highest-rated) ### 5/5 — Top calculator *2024-10-16, version 4.3* An excellent calculator would have liked the option of adding the conversion element to the standard, however the basic calculator is very good and is fine for my use. ### 5/5 — perfect *2024-10-05, version 4.3* A perfect calculator. I never use anything else. ### 5/5 — App no good *2020-11-24, version 2.3* This app was good before IOS 14.2, does not work with iPhone XR, don’t try to get support because safari can’t open website. ### 5/5 — Not supported on iPhone 11 Pro Max *2020-04-29, version 2.3* Garbage developers can’t keep up with new Apple and there changes now after having this app since 2010 or so I can’t use the conversion portion ridiculous. ### 5/5 — Great calculator app *2018-06-24, version 2.3* You can turn off order of operations, Great! ### 5/5 — Great Calculator *2018-05-15, version 2.3* Love the large, easy to read numbers.

I use this calculator daily, it is easy and has great features. ### 5/5 — Perfect *2017-11-06, version 2.3* I love that it has no adds, and for my OCD it has a page where I can go back and see everything I've done. Wouldn't change a thing. ### 5/5 — Best Calc App in the App Store! *2017-09-09, version 2.3* The facts are: 1. Free 2. No Ads 3. Free Backgrounds 4. $1.99 for all features 5. HD 3D graphics 6. Tried everything else! This is the one, your search is over. Get it Now, no kidding. Most people will love it unless you need a graphing calculator, it does not do graphing but I do not need that. I bought the extra features including tip calculator, loan calculator and all scientific functions, it was a real deal! Other calculator programs want a monthly subscription for premium features, no way! Finally the perfect calc app, love it. ### 5/5 — Does everything you need *2017-09-03, version 2.3* The title says it. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
