How Hone works
You hear two short sounds, A then B. Tap the one that fits:
Pitch: tap the tone that is higher.
EQ: two pink‑noise bursts. One has a boost at a hidden band. Tap the brighter, boosted one.
Right answers shrink the difference; misses grow it. The gold line trending down is your ear getting sharper. Your level is your real resolution, and Hone remembers you so every session resumes at your level. Tap AI anytime for a coach read and what to work on.
