Good combination of multi-function capability, settings, and ease of use with a very attractive skin. You do have to play awhile to learn how to use it- for example, there is no MC key- to clear the memory you press and HOLD the C key. But it's worth the play- the calculator is far superior to the one on my premium level tablet.

I've literally downloaded dozens of calculators trying to find the best one. I feel this is it! No ads, customizable calculations, simplistic look. The only improvement would be to add a feature where the calculation will continue every time the = is pressed (2x2=4=8=16=32...) still 5 stars and the best calculator app out there.

This is the best calculator I ever had in my phone, and I've tried a few! I don't even want to hear about the others. Very customizeable (buttons, number format, precedence of operation, rounding rules, and even more exotic things), useful memory and calculation history functions, easy to use and at the same time, packed with advanced features! This app does an outstanding job of providing a calculator that is good for basic things, but that allows you to tinker with the fine details, if you would like to. And on top of that, it's free! Is it OK for me to be this excited about a calculator?
