Free version of the app is setup for a six-string acoustic or electric guitar with open strings tuned to E, A, D, G, B, E. Two premium features are available for one-time purchase and do not expire: (1) Note to Play Settings -- the musician can also choose whether the note cards (a) include sharps and flats or natural notes only, (b) are in order or shuffled, (c) are repeated, and (d) have the fret to play displayed. (2) String Configurations -- the string setup can be changed from standard 6 string guitar to anything from 1 to 12 strings with any starting root note and root fret for each string. This allows the app to be used for non-standard tuning as well as other instruments including bass guitar, ukulele, and 4 or 5 string banjo.
