Calculator Keyboard - Calku

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.

Thank you for great app Please bring history button to main page

I came into this app by accident as I was not looking for a calculator, but I must say this app really works great! I have found this app comes in handy to do a quick calculation while in other apps. The app is easy to use and performs well. My thanks to the developers for a simple app that performs great. Job well done!
