I agree....the guy who gave it one star must be doing something wrong. It DOES work and it WORKS very well! Kudos to the author. PS dude....its not rocket science



Nothing to see here - app does nothing

So Glad This Transposing Wheel Works Perfectly

Just what I needed to transpose from any key to any key. Easy to use, just point the key you want to transpose on the little (inside) wheel to the key you want to transpose to on the big (outside) weel. The rest of the notes fall into place and you can transpose anything from there to the new key. Love It! Indispensable for my guitar playing.
