Best calculator - need optimization for iPhone X
2017/12/07

Love this calculator. The best Calculator on the App Store hands down. One small thing is it needs to be optimized for the iPhone X. When you swipe up to close the app, the keyboard registered a “,” or a “.” So when you open the app up again it’s there in the formula bar. other than that the app is perfect.

Like it, but UI fixes needed.

I have been using this for about a day now and I love it except for some UI issues. So I will be using my other favorite : Pcalc Lite half the time at least.1. Swipe up to switch between apps causes numbers to be entered. I am always switching back and forth between my data feeds and the calculator and every time I return, I need to delete unwanted characters from the swipe up gesture. Really annoying to do this hundreds of times a day. Pcalc does not have this problem, so please do what ever they are doing to fix this annoyance.2. You need slightly different color shades around the numbers and another different shade of gray around common operators to guide fast number entry. The two color UI is kinda pure but not worth the slowdown caused for entering numbers. People like me are switching back and forth between multiple engineering apps each with its own key layout, multiple times per minute. So a bit of guidance through color is useful. Again, look at Pcalc for a tasteful example.Also, it would be nice to get rid of the bright background on the answers and just use white text on black - just a personal preference. Thanks for this awesome app!

Another Movie Buff
I used the prior version of this app until I updated my devices which killed that version.As a retired IT professional I have mixed feelings about this situation. I am a bit surprised that the prior app could not be altered to run under iOS 11 but as my programming has been for *nix & Windows I cannot make an informed judgement there. I also understand that the app developers have to receive a reasonable return on their time.I am giving this a 4 star review with very little exposure to the app & hope this version will perform as well as the prior one did. After more time with the app I will update this review & expect this text to be replaced by a 5 star review.

Custom Functions Disappearing ☹️

I’ve used this app for a long time and bought the subscription. It’s the most useful calculator I’ve found. Except my custom functions randomly and repeatedly disappear. One of the nice things about this app is the ability to define custom functions (which I’m doing a lot of for statistical distributions) but they keep disappearing from the function list. I’ve resorted to keeping a saved session with all the definitions and I have to just periodical change the session, copy the function, paste it, press enter, re-add it as a new global function, and switch back to my “working” session. It’s kind of a tedious and annoying process. Please fix! 🙏 or tell me what it is I’m doing wrong.

- fix for crash when changing plot settings on recent iOS versions - fix for iOS keypad covering bottom of the input field - fix for problems with online sharing
