Before I signed up with Skritter, I read a lot of comments about how it would not run on Android. I tried the desktop version, that did not work for me, in the preview. Issues were trying to write with a mouse, and my OS being Linux.
But I signed up anyway, hoping to find a working solution. Now I am using Skritter on a Samsung Galaxy Note II. It is not perfect, but works well enough for me, and I can't imagine any desktop method with a mouse could be this good. Writing the characters with a stylus is great! Running on Jelly Bean. Maybe I did a separate install of Flash, I don't remember.
