To be honest I can’t think of a year (since it came out) where I wouldn’t have ThumbJam in my list of fav apps. It has to be in my list of 24 apps for 2012 simply because I keep going back to it. Keep on using it and loving it and trying it in different ways.
It’s an amazingly versatile app and, in my view, a very expressive and creative instrument.
If you haven’t tried it then you don’t know what you’re missing.
