I just made Inkpad, my vector drawing app for the iPad, free software. I'm releasing it under the Mozilla Public License, v2.0. It requires iOS 7 and is currently "in review" at Apple. I've spent the last few weeks updating it for iOS 7 and cleaning up the code for public release. There's a lot of code, however, so I'm sure there are still many untidy bits. If you'd like to contribute, I'd appreciate bug fixes, new features, and localizations for your language of choice. Otherwise, I hope you can learn something from it, or find bits and pieces that are useful in your own apps.
