I've been using this calculator for more than 4 years. It is the best calculator out there and it meets all my needs. After testing the app, I decided to purchase the pro version to get rid of ads and unlock full functionality. The small one-time fee was worth it. The developer constantly improves the calculator mostly by adding support for more advanced calculations such as series, matrices, integra, solving ecuations, etc. (interface/look as far as I can tell doesn't change much - a plus).

Amazing calculator by very passionate developers. My favorite feature BY FAR is custom layouts. The Casio-like layout was not enough like the Casio Fx-115 ES Plus / 991 EX, so I made it my own. I love how the buttons on the calculator are not sharing borders with each other, so if your aim is a little off you won't have to worry about accidentally pressing another button. One other thing, the icon for this app is unattractive, but it doesn't detract from the quality of the app.

I continue to be amazed. They released version 10 today. They added limits, infinity, variable and function menus, and more. This is the most functional calculator I've ever used. You can build custom button layouts. You can program your own functions. It can solve equations and graph them. It has a full range of unit conversions and mathematical constants. There's not enough space to list everything good about this calculator.
