See which elements you struggle with, watch accuracy climb, build a streak.
Most ear training apps flood you with features. Coco strips it down to what actually works: short daily sessions, honest feedback, and structured progression backed by research.
Notes, Intervals, Chords, and Scales — four focused courses from beginner to advanced. Each has structured levels so you always know what to practice next.
See your accuracy for every note, interval, and chord. Track response times, spot weak areas, and watch trends over weeks — data that guides your next session.
No retries. No hints. No inflated scores. Honest feedback based on peer-reviewed studies of pitch acquisition. If you get it wrong, you learn from it tomorrow.
Every practice level starts with a short theory lesson — see the notation, understand the concept, then train your ear to recognize it.
Each session is 25 questions. Five minutes of focused practice beats an hour of mindless drilling. Build a daily streak and let consistency do the heavy lifting.
From music students to professional performers, Coco is helping thousands develop the ears they've always wanted.
"After 3 months with Coco, I can finally identify notes by ear. The daily practice is so manageable, and I love seeing my progress chart climb!"

"I'm 45 and thought it was too late to develop perfect pitch. Coco proved me wrong. The science-backed method and realistic expectations kept me motivated, and now I'm recognizing notes I never could before."
