Ratings and reviews

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.

With this app you can not take a COPY of an amount from elsewhere and PASTE it into the calculator. (The most important reason to use a calculator, is to calculate difficult big numbers) A few additional MEMORIES will be handy too. 4 stars overall, mainly for the other useful calculations and conversions available on the app.

Always my best calculator app, but upgrade is needed to add binary, hexadecimal and decimal conversation for programmers utility accessible via more menu. 5 stars rating given already. With this update request should exist 5 stars rating if possible.
