Notability: I kind of didn't want to pin this because I think this app, like a bunch of other note taking apps, ripped off one of Dan Bricklin's awesome handwriting innovations. When it dropped to 99 cents I thought I'd try it. It is a pretty sweet app with some great features. I'll probably still buy Dan's Note Taker HD to support him but Notability is still worth a pin, especially at this price, it is a fantastic note taking app.
