Frustrating! – Fret Trainer - Learn Fretboard Review

Given the other reviews I’m sure it must be me but this was an exercise in frustration trying to use this app. I only managed to use it for the most basic feature (finding notes) and then I deleted it after not finding any source of instruction or tutorial about how to use the other features.
