Wont get you very far
This app would be okay for someone who has just picked up a guitar but it would fail anyone looking to advance their skills. On the upside you can practice new chords in real time with accompaniment. What it does not teach is technique - strumming, picking, notes, chord structure. Its monkey see monkey do only. Its not expensive and it looks like it was designed for toddlers which sometimes isnt a bad thing. I need something.a hair more advanced so this wont do.
