The perfect calculator

I’ve been using this calculator for 10+ years and it’s all I’ve needed. I use it almost every day. Very simple and easy to use, the main feature that sets this apart for me is the previous calculations screen with tap to copy/paste.

Solid, Premier, just the best

I have been using GoodGrapher pro since the iPod Touch gen 4 - and I have never used any other calculator app ever since. It is superb. If I could ask for one new feature it would be the ability to write custom functions (as it looks like the developer is not making updates). I cannot give this higher praise than 10 plus years of use.

Great and could be even better

Best for what I wanted. Would love to have the possibility of graphing for some discrete parameter values. Say y=x^p and choose p=1,2,…,10
Hope you can add that!😄
