Scientific, programming, finance, graphing, everything. Well worth it to purchase all modes, incidentally getting rid of the adds. ### 5/5 — Scientific Calculator *2019-03-29, version 6.6.0* This app fits my way of using a scientific calculator. The biggest use for me is the scientific mode and conversions. So far, I have not been disappointed. ### 5/5 — This application *2018-11-09, version 6.6.0* I love it love it love. Provides enormous info about almost everything. ### 5/5 — Great App *2018-04-28, version 6.6.0* Very nice app. I use it almost everyday ### 5/5 — Extremely Useful *2018-02-24, version 6.6.0* Been using this app for years now. It is extremely useful to have multiple types of calculators in one app. Well worth the price. Use it all the time. ### 5/5 — Easily the best *2018-01-21, version 6.6.0* One app does the lot. I use nothing else. ### 5/5 — Calc pro *2017-11-10, version 6.6.0* Great app. Purchased for my I phone 3G a few years ago. Loved it then on phone. The app meets all my needs. I really like the HD version for IPad the tape portion of it is very useful to see what you have entered into box ### 4/5 — Very helpful *2017-07-16, version 6.5.0* Well designed. ### 5/5 — Excellent App *2017-06-01, version 6.5.0* A must have for all around math problem solver. ### 5/5 — 👌🏼 *2017-03-17, version 6.5.0* Best calculator hands-down ### 5/5 — Best Calc app *2017-02-16, version 6.5.0* Love this app. I bought the app to get rid of the ads. The tape is great, and the fact that you can see all transactions and touch one to have it copied to the calc screen is very useful. I only use the basic calculator, but the others seem to be very valuable to esoteric users. ### 5/5 — Excellent reliable calculator *2017-01-23, version 6.5.0* Although I don't need anything that does as much as this calculator does, I love working with it. This is my go-to calculator. ### 5/5 — All-In-One Calculator *2016-12-31, version 6.5.0* This calculator has every option I can see myself ever needing in a calculator. It's all laid out in an easy to use format. Highly recommend installing this on your iPad. ### 5/5 — Agree, this should be your first calculator app. *2016-12-27, version 6.5.0* It literally has everything you need . . . unless you are a quantum theoretical physicist. Well, even then it is likely to be your go to math app. Curt ### 4/5 — Great utility *2016-12-23, version 6.5.0* Excellent and does what it advertises. ## Most critical reviews (10 lowest-rated) ### 1/5 — Stopped working/redownloaded/demands payment again *2021-01-23, version 6.6.0* This app stopped working (after it being paid for). I deleted and reinstalled it. Now it demands payment or shows full screen advertisements. When I select “full version,” I CAN’T PAY (because I already have), and downloading again just gets more of the same garbage (I’d use stronger language but want this to post so people know they will get ripped off). ### 1/5 — now just crashes on both ipad and iphone hasn't been updated in years *2020-12-13, version 6.6.0* now just crashes on both ipad and iphone hasn't been updated in years. shame, this used to be the best calc app for a long time. ### 1/5 — Broken with iPadOS 14.2 *2020-12-10, version 6.6.0* App now crashes. No support available. ### 1/5 — Tape not working *2017-10-05, version 6.6.0* Just purchased. Tape not working ### 1/5 — IF... *2015-04-01, version 6.1.0* I would quit getting "Google" ads on this app AFTER I purchased it instead of using the free version, I would give it a higher rating. ### 1/5 — Why you charge me, $7.99 ? I paid full price long ago. *2014-10-18, version 6.0.0* Cheating costumer, Beside it does not work well. Very difficult and cumbersome to use. ### 1/5 — Calc pro *2012-03-29, version 3.6.5* I bought the upgraded version in order to get everything. On my trip to Ghana I realized it did not have the Ghana currency in it. I also do not like that the calculator does not show all the numbers you have have entered. Most high end calculators do that. Save money get something else. ### 1/5 — Not worth the money *2011-11-19, version 3.5.6* I really dislike this app - in fact, I'd rather pull out the simple calculator on my iPhone vs. using this full featured app. The problem with this calculator is that it tries to do too many things and thus doesn't do any of them well. Seriously - who needs a base conversion calculator? For the 10 people who might need this, make it available as a setting or menu option but to put it in the main interface is just cluttered. I especially hate the column of calculator types that line the left side of the interface. There's no way to lock a particular calculator into place, so I constantly find myself flipping to another calculator by accident. Furthermore, you just need to swipe left or right to move between the various calculator. I'm constantly swiping accidentally to another calc when I'm typing in numbers. Overall, very very disappointing. I've deleted it off my iPad and I'll be looking for a better, simpler calculator. ### 2/5 — Why can't omit the result directly? Can’t the tablet and the phone share the same version? *2020-11-15, version 6.6.0* Why can't omit the result directly? Can’t the tablet and the phone share the same version? ### 2/5 — Financial Calculator *2015-12-09, version 6.3.0* The financial calculator is too basic. Especially after paying $$$$. The mortgage calculator is limited too. I was trying to compute a mortgage amount given a specific payment, interest and term. Fix this and earn 5 stars. Thanks ## Most praised reviews (10 highest-rated) ### 5/5 — Best Calc App Ever! *2024-09-03, version 6.9.0* This app calculates pretty much anything you need it to, in algebraic form or RPN. everything from “normal” functions, to stats. It converts units, and it converts world currency. And if you’re into science, you can pick from its myriad of constants. ### 5/5 — Calc Pro HD *2024-07-01, version 6.9.0* Best calculator I have ever used. It has everything! ### 5/5 — Great calculator with no subscriptions *2024-01-18, version 6.9.0* Multiple calculators in one. Easy to use and great functions! And it doesn’t have unnecessary tracking like some others. Great value. ### 5/5 — Fantastic App *2022-03-13, version 6.8.6* I love this app. I use it almost daily. I greatly recommend it anyone. Thank you for developing this app. ### 5/5 — Calculator *2022-01-14, version 6.6.0* Excellent tool for your daily calculations on any fields ### 5/5 — Well Done! *2021-04-18, version 6.6.0* Finally, an iPad calculator with enough functionality for a young student to a NASA engineer. Nothing missing. Works perfect. Worth every cent. Well done! ### 5/5 — Best I have tried *2020-03-06, version 6.6.0* out of about 6 calculator apps I’ve tried on my phone Calc pro exceeds all of them. It’s definitely worth getting the paid version. ### 5/5 — Full cool *2020-01-21, version 6.6.0* C gebre full cool Wesh shu wet ### 5/5 — $$$ *2019-09-02, version 6.6.0* Easy to use and understand I even paid for the pro version 😎 ### 5/5 — Great app *2019-07-27, version 6.6.0* This is a wonderful calculator. I use it for work almost every day and it is perfect. I mostly use the basic calculator, but the currency calculator is also very useful as is the metric converter. I also find the tape feature to be extremely handy. Some users might also find the other modes such as scientific and graphing to be valuable. Finally, it is worth the money to buy the app in order to get rid of the adds. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
