Never liked the calculator that came with the phone. Found another app that I liked but it seems that updates over time began to make the app hang up as well as the phone. Stumbled on to this one by accident and I love it. It's smooth and the several different themes means there is one you will probably like. It is both a simple calculator and a trigonometry calculator. I couldn't ask for more.

Should had given 5star but for not having the +/- key. Provide the key and have my 5star. Give us the +/- key for easy and direct additilon and subtraction calculation.
