Harmonica Key Pro lets you unleash the power of your harmonica. Use it to quickly reference keys, positions and scales between the most common harmonica tunings.

With improved reference notes you can also practice getting that bend perfect.

From the stage to the side of the Mississippi Delta, this is the tool harmonica players need. Made by a harmonica player, for harmonica players.

Note: This app is for diatonic harp players. If people really like it, maybe we will do chromatic next! Stay tuned.
