There is something similar for iPad (I did try the free version last year).
But I found it clumsy, and slow.

The above free version is only single stave, and I didn't fancy shelling out £30.00
for the full version.
It has had a few updates since I tried, so maybe it has improved.
The OP App does look great though, and very, very usable.
