Pitch trainer - Harmonize

Harmonize is an ear-training app focused on just intonation to help you develop a stronger sense of pitch. Users listen to basic intervals and harmonies such as octaves, perfect fifths, and major thirds, then attempt to recreate the sound, training the ear through listening and pitch matching.

Guided by the cute character Ebifurya, no prior music theory is required. The app encourages natural ear training by listening and matching pitch, supporting singers, brass players, and orchestral musicians in achieving better intonation across karaoke, choir, and ensemble settings. The app is free to download and designed to be fun and effective for developing relative pitch.
