Non standard division and multiplication
This app seemed so promising that I bought the premium version. Unfortunately, it uses what seems to be a Unicode version of division and multiplication which isn't recognized by my math application. Bit of a deal breaker. Please add an option for standard multiplication and division.
Very nice
Very nice and handy Only thing I wish it had is vibration on touch.
Doesn't work
Worthless app. I installed it and it doesn't work

Great utility.
Makes using the keyboard much easier. Makes using calculations much easier than using the dedicated keys on a alpha numeric type keyboard on a standard keyboard layout. Very helpful when using iMessages when showing calculations to others.
No purchase
Free app enough
如果支持小组件就行

Doesn’t work in iPad Pro 2021 iOS 14.6
Can’t get it to “Add Keyboard” on iPad Pro 2021 iOS 14.6. Instructions leave a lot to be desired. Not recommended.
تطبيق جميل جداً
يخليك تستغني عن الخروج من المحادثة علشان تحسب على حاسبة الجهاز
زۆر تايبەتە، amazing
زۆر تايبەت و ناوازەيە دەتوانى لەگەڵ كيبۆرد بەكارى بێنيت
Great idea 💡
Is very useful but sometimes is buggy 😊
Great idea!
Pretty great idea for an app! Works flawlessly and I like the “keep result only” setting.
