About the app

Harmonic Recovery is a music player made for diplacusis: when music sounds out of tune because each ear hears the same note at a different pitch. It often follows sudden hearing loss, Ménière’s disease or an acoustic neuroma.

In Training mode, the listener’s own songs play clearly in the affected ear while the same music fades in and out in the other ear as a pitch hint. A pitch-matching check measures the gap between the ears in cents, so people can see whether it changes with practice.

Built by an independent developer who has diplacusis, it is not a medical device, promises no cure, and keeps results on the device.

Background: why I built it, how it works, and the research and its limits.
