Guitar Trainer 1.0.6
Guitar Trainer is an application for mobile devices that helps musicians learn the fretboard of their stringed instrument thoroughly. It supports guitar, bass, banjo, ukulele, and mandolin (in standard and alternate tunings). It includes a training mode, a game mode, and a tuner. It should work on any Java device supporting CLDC 1.1/MIDP 2.0.
The octave of Ukulele tunings was fixed so that the tones may be more audible on some phones.
