Finally, I've been working on creating StitchSketch for Android.
Actually, my ultimate goal is to combine the KG-Chart and StitchSketch, and make it run on all platform (iOS, Android, Windows, Mac)
I think the Android version is now about 20% progress.
If you could comment what type of Android device you are using, I'd really appreciate it.
Right now I'm using a couple of Android Phone and tablet for dev/testing.
