Just wasted $0.99 on an app that does not work with iOS14. This should be in the description. It’s very deceiving. ### 1/5 — Doesn’t work on iPadOS 13 *2020-02-08, version 1.2* I don’t understand how dated this app is. The help/info icon shows a steps which is no longer available. It doesn’t show up as a widget you can add on the left widget screen on the home screen either. Waste of money should have some kind of warning ### 1/5 — Fix text color! *2019-12-20, version 1.2* Under new iPadOS, the result window is unreadable - black on dark gray. Please fix this! ### 1/5 — Not works !!!!! *2018-01-15, version 1.2* The app not works in iOS 11 ### 3/5 — Good, needs work *2020-09-24, version 1.2* Cannot read result due to lack of contrasting colors. ### 3/5 — Can’t see . *2020-08-13, version 1.2* Handsome app but can’t see figures in notification center. Sad face. ### 3/5 — Works fine, looks poor *2015-06-05, version 1.2* I like having a calculator available quickly in widget form. On my iPhone 5S running 8.3 the numbers and symbols on the calculator are rendered with an underline. This should be fixed. ### 3/5 — Backspace Button Pixelated *2014-11-02, version 1.2* The backspace button on the iPhone 6+ running iOS 8.1 looks pixelated on the Today screen. ### 4/5 — Need to fix text color to support dark theme *2019-10-09, version 1.2* Great app. When used as widget in ios 13 dark theme, the calculations window text color is black on gray background which makes it very hard to use. Hope this bug will be fixed soon. ## Most praised reviews (9 highest-rated) ### 5/5 — Nice *2017-07-26, version 1.2* I usually don't buy apps, but this one is definitely worth it! It's nice to be able to use a calculator without unblocking my phone ### 5/5 — Good widget *2017-04-06, version 1.2* Thanks for great widget but how about light background? ### 5/5 — Love it *2016-02-05, version 1.2* I like how it looks like the Calculator widget on OSX Notification Center ### 5/5 — Excellent *2015-04-11, version 1.2* It does exactly what you would want it to do and works great. Just wish calculator was collapsible and/resizable ### 5/5 — NiCe !!! *2015-01-11, version 1.2* This should've been a new feature added to the native calculator app for iOS 8. But since it isn't, it's nice to see that someone else thought of it and created an app with the same design aesthetic as the native app. If you use your calculator a lot and get tired of having to unlock your phone to use it, try this app out it's real cool and very handy. ### 5/5 — Cool! But improve landscape mode in NC! *2014-10-29, version 1.1* Cool! Got it just before Apple changed its NC policy! But improve landscape mode in NC! ### 5/5 — Great Basic Calculator Widget *2014-10-22, version 1.1* You can not only the app for a calculator but you can also make it a widget so you can use it on the go or even on your lock screen! Great App, hope it gets popular! ### 5/5 — Works! Easy! *2014-09-21, version 1.0* Works as described. Very simple. If you use your calculator a lot, the app for you. Mimics the iPhone's standard calculator in both style and functionality. You are able to access this from the lock screen if you have Notification Center enabled for use with the phone locked. ### 4/5 — Slow.. Gut great!! *2015-01-02, version 1.2* The app is a little slow to working... But when the first lag is gone its perfect!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
