Great UI, but...
I really like the apps UI, where you can scroll among the functions and have an easy access to history.
But... I just played with it a little bit and found computation bugs: comb(3;2) does not yield 3, its 6 !!!
I cant really rely on a calculator that does not yield good results :(
Also, please order alphabetically the functions in the help section; thatll make it easier to find the help you need.
Also, why not auto-complete parenthesis ? For example, you force the opening parenthesis in the square root function. Provide the closing one (or just dont force the opening one).
