Not a massive amount of functionality, but good enough for what I want to use it for, which is jotting down some quick and dirty tabs while I have my guitar in one hand and my ipad in the other. I like being able to define my own chord or note sequences and being able to insert them quickly. I havent figured out how to delete unwanted saved tabs though, and cant find instructions online. Paid for itself first time out just for the convenience, because I used to do all this on a piece of scrap paper.
