Otherwise great app. Best scientific calculator on iPhone. ### 1/5 — Does not work *2018-02-16, version 1.2* 2018 - just frozen. ### 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. ### 2/5 — Scientific calculator *2017-12-06* Simply does not work No access to developer ### 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. ### 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. ### 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 ### 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 ! ## Frequently asked questions about Calculate ### What does the Calculate app do? The Calculate app is a fully-featured scientific calculator designed for complex mathematical operations.
