Just wasted $0.99 on an app that does not work with iOS14. This should be in the description. It’s very deceiving. ### 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. ### 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! ### 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. ### 1/5 — Not works !!!!! *2018-01-15, version 1.2* The app not works in iOS 11 ### 5/5 — Nice *2017-07-26, version 1.2* I usually don't buy apps, but this one is definitely worth it!
