Tone - Learn Perfect Pitch!

Tone is a fun and accessible ear-training game designed to help you develop perfect pitch. Choose pitches and octaves, scale difficulty from easy to expert, use practice mode with a reference pitch, and transpose notes across keys. View note names, piano keys, or solfege while you train, and track your progress with beautiful graphs. All data is stored in iCloud so you’ll never lose progress.

Features include score sharing to compete with friends, recognition of musical intervals and chord qualities, and a visual history of your improvement.
