Coco - Ear Training Tone Gym
iOS Universel / Education
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!"

Quoi de neuf dans la dernière version ?
Coco 3.0 is the biggest update since launch. Here is what changed.
A WHOLE NEW LOOK
We redesigned the entire app: bold colors, high contrast, and a cleaner layout that puts your daily training front and center. Every skill family now has its own color, so you always know what you are working on.
ASSESSMENTS
Three new tests measure your ear: pitch acuity, relative pitch, and absolute pitch. Take them anytime to see where you stand, and retake them as you improve. Pro members unlock the full report and history.
A NEW PITCH GAME
The pitch game is now a tuner. Listen to the target tone once, then drag the ruler until your tone matches it. One listen, one answer, all ear.
THEORY LESSONS, REBUILT
Lessons are now swipeable slides with interactive piano and staff diagrams you can tap and hear. Quizzes let you retry until you get it right, so you move on only when the concept is truly yours.
A NEW "ME" TAB
Your stats and profile now live in one place: streak, accuracy, and your progress over the last 7 or 30 days, all at a glance.
LEADERBOARD
A new podium design, and your row stays pinned on screen no matter where you rank.
ITALIAN AND SPANISH
The app is now fully available in Italian and Spanish.
AND MORE
- New results screens after every game, lesson, and daily workout
- Games start with a quick countdown instead of an extra screen
- Exercises and levels load noticeably faster
- Smaller download size
- Many small fixes and polish throughout
