What is Processing
Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.

Processing was initiated by Ben Fry and Casey Reas.

Some issues need to be fixed

I really want to rate this app 4-5 stars because it's an amazing idea! However there are some issues. First, it's not immediately obvious how to back out of a running sketch. You have to tap the thin grey line at the top to back out. (I only figured it out by accidentally hunting and pecking around.) another major issue is that changes in source are not run until you force quit the app using the iOS task mgr. I'm not going to mention the other issues that have already been highlighted by others. If these issues are fixed this could easily be a 5 star app.

Nice but...

It's great to be able to learn and practice on the go and all credit to the creator of the app, but without a way to import, share and export your projects, it's for amusement only and you can't do real work. The app also needs landscape mode so it's a bit easier to type and the ability to either import or paste text from other programs. Otherwise, making anything longer than a flashing rectangle just takes too long.

I have been looking for something like this!

I have tried codea and pythonista, but i never could really get the hang of lua or python. I am familiar with gml, so i love this app, but the typing controls really need some work, copy/paste and import/export REALLY need to be added, easier conrols for quitting the game or typing, but after they're added this will be the best free app i have ever had on my ipad. I really hope this gets updated soon!
