Procoding uses HTML5 APIs (e.g. Canvas) and supports processing.js, a JavaScript port of the Processing language. Procoding relies on Mobile Safari. Therefore some features of Processing aren't supported:
· 3D (P3D) and WebGL require iOS 8
· No external processing libraries
· Modified processing.js source code and additional reference documentation available on

· iPad, iPad mini, iPhone (incl. iPhone 6) or iPod Touch
· iOS 7 or iOS 8 (recommended)

Improvements & Bug Fixes
- New Feedback Panels (HUD)
- Sketch name prompt for new sketches
- Fixed webserver issue after toggling Bonjour service without app restart

Customer Reviews

Application Requires Update!

Hardware: iPad Mini 2
OS: iOS 8.3

I purchased this app in December 2014, and it worked as expected with no issues. However, with subsequent iOS updates, functionality suffered, and as of the most recent iOS update, this app is no longer functional.


NOTE: I also use this application on my Mac Mini (late 2012; latest version of OS X); and it works great. I know the Processing app for Mac OS X is free, but this application is worth looking into.

Slow and buggy

I've tried to find an app for Processing to code outside my computer area, but I'm convinced it just doesn't exist for the iPad.

This iteration has decent keyboard support (unlike the native processing app), but everything lags on my iPad 3. Some commands are ignored (size) which makes composition on a custom background impossible. The text area flashes and doesn't seem to have any indication for toggling and going back to the editor might end up with garbled code. If it were free it wouldn't be worth the hassle.
