Ratings and reviews

It has many great, easy-to-use features! The ads aren't too bothersome. The loading time for 3d graphs isn't bad! I'm a fan! I've only used some of the features, but I haven't encountered a bug yet! It's free - why not try it to see what you think? Edit: After 10 years, this is my go-to calculator for the convenient keyboard, window mode, and built-in graphing.

The closest thing to Speedcrunch I've been able to find for Android. All it's missing for me is some basic decimal-whole conversion functions like Ceiling, Floor, Round, etc. Perhaps integrating some simple conditional functions like If()Else() into function creation, along with actual comparison symbols (<, >=, etc) wouldn't require using the current conditional functions like eq(), lt(), etc. Otherwise, it comes in handy for back-of-the-envelope calculations too complex for the default calc.

I love all the unique features of this calculator. The quick access to engineering functions, ability to create my own variables, window mode, angle and base conversions... I could go on, but I am ever so slightly disappointed that there wasn't an option for Dozenal. It's the only thing I have a second calculator for.
