移調ヘルパー - Transposing Helper

What does this do besides nothing? Agreed — I can transpose faster in my head.

I must be doing something wrong. Because this does nothing. You spin the wheel and then what? I can do it faster in my head

Nothing to see here - app does nothing

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

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.

That guy who gave it a 1 star doesn't know music theory. This works perfectly fine, it is just a simple wheel that helps you transpose chords, just like they teach you in school.

unlike another app I tried which only worked on the iPod touch, this one actually works on the iPhone 5s. Easy enough to use

Nice

This app is useless! Do not download unless you are bored out of your mind. It transposes nothing! Nothing at all. I waisted an hour trying to make it work! I got nothing! It is the nothing app! I've played guitar over forty years and was looking for a quick transposer, this ain't it!!! Delmarplays

Such a simple tool is so useful. Thank you for making simple.
