About this app

Can you hear the difference between a note that's perfectly in tune and one that's just slightly off? Microtonal Ear Trainer builds the listening skills many musicians never develop.

Designed by a musician, for musicians. This app focuses on one thing and does it well: training your ear to detect microtonal pitch differences that many people can't even hear yet.

Each round plays two tones in sequence. Your job is simple: is the second note flat or sharp? The deviation is random, anywhere from a subtle 1 cent to a wide 100 cents, and the difficulty is yours to control.

With consistent practice, you'll start hearing pitch inflections that used to be invisible to you. Whether you're a vocalist trying to lock into a chord, a guitarist chasing pure intonation, or a composer working with microtonality, this app trains the one skill no instrument lesson covers.
