Best calculator I’ve found!
I've tried dozens of calculators for simple four-function calculations, and this one beats them all hands down. Beautiful display – I can't say enough good things about it. Thank you, developer!
Great calculator for iPad
Love this calculator for my iPad mini. It has several themes and works great every time I open it.
Perfect for everyday use

Best simple calculator, and here’s why
It has full memory buttons. There’s no excuse for a calculator not to have them, but many don’t. It also displays the value of the memory which comes in very handy. On top of that, it has easy cut and paste buttons, which also come in very handy.
Great user interface!
The app has a clean, visually appealing, and easy-to-navigate user interface that makes it simple to use and enjoyable for the user.
