Nice, but...

... a lot of symbols missing. Using the app ist is just possible to mark the strings. Symbols for a strum direction, repeats, devidere, and so on are missing. You should add all the symbols a guitarist needs!
By the way: once you inserted a whole new line, it is not possible to remove it. So you have to enter all the entered figures in a new file.
So I can resume: horrible and not worth any penny!
