Hi all,
I have just released a Scratch clone running on iPad. It is based on Scratch 1.4 from the MIT Media Laboratory. The app is now called "Pyonkee" - freely available on App Store. https://itunes.apple.com/us/app/pyonkee/id905012686
Pyonkee was originally started as a fork of John M McIntosh's Scratch Viewer. https://github.com/johnmci/Scratch.app.for.iOS.
While Scratch Viewer just works as a viewer of the existing Scratch projects, Pyonkee supports creation/edit of projects.
Other features: - User interfaces are optimized for iPad - Native font support - Embedded camera support - IME support - Auto-saving project - Sending projects via e-mail - Project import/export through iTunes (currently disabled)
Moreover, source code is open on github. Feel free to fork it. https://github.com/SoftUmeYa/Pyonkee
Enjoy!
