You Still Need a Pretty Good Ear – Chord Tracker - US Review

Over all it’s okay. It gives a pretty good idea of key and works well for major chords. But it has difficulty distinguishing between Major 7ths and Minor chords (like Cmaj7 and Em for instance), and it misses subtle chord changes a lot (C to C7 for instance). But it’s free and it provides a solid start, so 3 stars.
