GridChord app for iPhone and iPad

GridChord plays basic chords on root notes in a diatonic scale.
It helps you hear the chord and the chord progression, and learn each note.
Its also a good tool for learning to read music with scale degrees.
Use it for searching/learning chords for a tune, building your solos from chord tones, or for studying music theory.
