I went over there and saw there were only major and minor triads. No augmented or diminished chords and no 7th chords. You might be able to play along with pieces, but don't expect to get any life into it.
I compared the chords given for Every Breath You Take with the first site the search engine gave. There a lot of chords had added 9ths or were suspended 2nd chords. From what I understood about Andy Summers' playing that is more what I would expect. So i guess the developer still has some work to do.
