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!"
