@teledyn sorry (not sorry) for jumping in, but you didn't provide an answer at all.What you did was to chastise OP for asking for an app, and 'splaining that the requirements would be fulfilled by listening to songs and mimicking them -- which they aren't, as a dedicated teaching app/site will provide _which_ intervals, chords etc are used, something most people won't know just by listening to a record even when they can mimic the playing.So just don't be obnoxious to strangers.
