Go-To App for so many things...

I started using CodeRunner 1 a few years ago during my studies and it has been a wonderful app. This won’t replace a full-blown IDE, but its simplicity and quickness are wonderful. You should get CodeRunner 2 if you are…:

…learning to program, because it requires no setup like most IDEs do. You can easily & quickly play around and enjoy your journey into programming languages.
…teaching peope how to programm. No UI Clutter, no bulky interfaces. Just you and your code.
…a developer. Developing algorithms and playing around with code in a separate environment is very useful.

And for me Version 2 is an improvement in any way:
- break points are a game changer
- improved UI and autocompletion
- NO MORE TROUBLE with SANDBOXING. The transition between the AppStore purchase and the downloadable version was painless and silky smooth. Thank you! <3
