New here? Start with the Daily Workout — 5 minutes a day is all it takes to hear the difference.
Description
Train your ear like a pro in just 5 minutes a day.
Coco is the ear-training studio built for serious musicians: real Grand Piano audio, seven focused games, and one score that proves you're actually improving. No browser. No laptop. Just your ears, your phone, and measurable progress.
REAL PIANO, NOT MIDI
Every interval, chord, and scale is rendered live from Grand Piano samples — no synthetic loops, no compressed MIDI. The cleanest, most musical training audio on iOS.
SEVEN GAMES — ONE FOR EVERY SKILL
• Sonar — pitch identification
• Triad — chord quality
• Climb — ascending intervals
• Fall — descending intervals
• Blend — harmonic intervals
• Ladder — scale identification
• Span — interval comparison
Plus daily worldwide challenges to train against real musicians, on your schedule.
ONE SCORE THAT MEANS SOMETHING: THE COCO PERFORMANCE INDEX
Stop guessing whether you're improving. CPI rolls your performance across every game into a single number — so you always know where your ear is, where it was last week, and what to train next.
DAILY WORKOUT — 5 TO 15 MINUTES
Coco picks the right exercises for your level every day. "Contrast before similarity" pedagogy builds solid foundations before the hard stuff. Most musicians notice the difference within 2–3 weeks.
THEORY COURSES, BUILT IN
Music Fundamentals · Scales & Keys · Intervals · Chords · Chord Progressions · Modes & Advanced Scales · Ear Training Theory — ~66 lessons, 285 slides, 70 test questions. Theory and practice stay separate, so you train exactly what you need.
WHO COCO IS FOR
• Guitarists, pianists, producers, songwriters, vocalists & DJs
• Self-taught players who want structure
• Students prepping for aural / conservatory exams
• Pros keeping their ears sharp between sessions
HOW IT WORKS
1. Pick a game or start your Daily Workout
2. Listen to live piano audio and answer
3. Watch your CPI climb as your ear sharpens
"Even after just a few sessions, I can already hear the difference! The other day I was casually playing guitar, not even my main instrument, and one I've never properly studied, and for the first time I started figuring out new chords completely by ear!"
Train your ear. Trust your ear. Download Coco and start your first workout today.

Coco now feels sharper, clearer, and more personal.
This update introduces a redesigned daily workout experience, helping you jump into focused ear-training sessions with a clearer path through today’s exercises. Your workout now shows progress, completion status, and the next drill to tackle, so it is easier to build a consistent practice habit.
We also improved onboarding with a more personalized training plan based on your goals and daily commitment, refined the games screen with clearer skill categories, and made progress, streaks, premium access, and daily challenge flows feel smoother throughout the app.
Also included:
- Improved Daily Challenge presentation and sharing
- Clearer locked-level and premium upgrade states
- Better home screen loading and refresh behavior
- UI polish across workout, games, onboarding, and progress cards
- Reliability improvements and bug fixes
Thanks for training with Coco.

Navigation
We’ve simplified the bottom navigation to focus on daily use: Home, Games, Challenges, and Me. The standalone Learn tab is gone so the app puts playable training and competition up front instead of a separate “learn” destination in the tab bar.
Games
Open the new Games tab to browse ear-training games grouped by skill area (notes, chords, intervals, scales, and more). Each game has its own levels and sessions. As you complete runs, you grow your Coco Performance Index (CPI): a solo mastery score that tracks how far you’ve progressed and rewards both depth and playing across games.
Challenges
The new Challenges tab is for async 1v1 duels: you and another player answer the same questions in the same order. Competitive ratings (Glicko-2-style per game/domain) move with challenge results, while CPI stays your solo progression—practice in Games, compete in Challenges. See season context, leaderboards, and match history, with flows to join, play your turn, and rematch where supported.
Home
Home brings together at-a-glance CPI, challenge rating highlights, daily workout game picks, plus streak and energy so you can decide what to play next in one place.
Improvements
Clearer structure for progression and competition, UI polish on the new hubs, and ongoing performance and reliability work.
