iOS developers TwoLivesLeft have just released an interesting new app called Codify, which brings touch based programming to the iPad.
The app allows users to create their own programs using the Lua programming language by typing code directly on your iPad. Also included are various assets and programming examples to be used in your creations:
Watch on YouTubeApps such as Codify are now possible since Apple relaxed their App Store rules that originally prohibited interpreted code in iOS apps. Apple now does allow for interpreted code to be run in-app, but still prohibits the download of such code. As noted by TouchArcade, this means that anything you create in Codify can't be exported (or imported).
I've heard more than a few developers attempting to create similar tools for the iPad, but all of them have hit various roadblocks in the Apple approval process because they all (in one way or another) allowed you to get code and assets onto the device and execute it. Codify sidesteps this by coming with a wide variety of assets, but unfortunately all of your creations will be trapped on your own device.
The developer has already submitted an update that allows sharing, but the developer isn't certain if Apple will allow it.
Due to the limited nature of the environment, the tool is mostly useful for experimentation and prototyping, as you won't be able to send your creations to anyone else. Still, it's an interesting idea and pushes the iPad into more content creation areas.
Codify is iPad only and is $7.99 in the App Store.
