Ratings and Reviews

Great learning tool


This is what students want — a way to take in text input, and produce text and graphical output.
We’d been using web services such as CodePad and IDEOne previously, but it doesn’t match this level of interactivity. Very nicely done.

Very useful


This is a very useful app if you need to write a function on the go or need to slove a problem. It helped me with my work so much. I think, every developer with ipad should have this one.



Magic Nano C applications. This application is very unique. It can display the results of a process graphics and text on a mobile device.
