Ukulele fretboard

Found an app so good, so useful, I can't believe it took me this long to find it. Saw it mentioned in a blog as the best of the type, and he's right. Select a chord, and the app shows all appropriate notes on the keyboard with the standard chord shape highlighted. The beauty of this app is you can quickly reshape the chord any way you like. It also shows the four repeated patterns for 7th chords, for example, down the fretboard. This is an incredible learning tool and a rescue tool -- need a different Ebm7? Punch it and select the notes best suited for your needs and your hand reach. An incredible app! And, of course, it's free. What a world.
