GuitarTrainer CE is a piece of interactive software teaches sight-reading for the guitarist and bass guitarist. It rapidly drills you until the note and its position on the fret board becomes instinct. Instinct on the Pocket PC rapidly becomes instinct on the guitar.
GuitarTrainer CE costs NOTHING and allows you to take your training to the road. It is a subset of the full-fledged GuitarTrainer PC, due to the limited Pocket PC's form-factor. However, it is ideal for day-to day training when away from your PC, when on a bus, train, plane etc.
Handy tool for honing your guitar skills.
