It's not bad – iWriteMusic SE Review
If you want to write scores for fun, then this is very useful. It's a little clunky and tedious, but for a free Iphone program, it is very useful and I would recommens trying it. But it would be useful to customize your bottom bar a little more so you don't have to keep tapping on "more".
