What a shame that the only other review for this app calls it "useless". I find it to be quite useful- it is a reference for working with guitar triads on the G, B and E treble strings. Mastery of these triads can really open up one's understanding of guitar chords, scales and playing lead guitar. But Here's the catch- this is not a hand holding tutorial app. You have to already have some theory under your belt to know what it is you're looking at. You have to have some understanding of triads and why they are so important to appreciate this app.
When these prerequisites are understood, this app becomes a wonderful reference for learning triads in any key, up and down the fretboard using inversions. Before I found this app, I was going to sit down and work out all the triads and inversions in all the different keys myself on blank fretboard sheets of paper. I kept putting this off as it was going to be very time consuming. Then I found this app and all the work is done for me! All I can say is thank you....what a terrific ready made reference. Kudos.....
