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.

I'm so glad you updated to the new Android Version. I have been searching since i had a new phone because the version was too high and i could not install on the new one. This is the best calculator because: -History -i can decide which results to save permanently -reopen calculations and edit -edit directly (not by arrow button) -big buttons -pinnable view -lightweight with all basic important functions for everyday use. Those features are what i couldn't find. I've missed it dearly!

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.
