About this app

Train your musical ear like a pro — anywhere, anytime.

Coco is the mobile-first ear-training studio built for adult musicians: real Grand Piano audio, science-backed pedagogy, and a Daily Workout that actually fits into your day. No browser, no laptop. Just your ears, your phone, and measurable progress.

BUILT FOR REAL MUSICIANS

Coco closes the gap left by web-only ear-training platforms. Every chord, interval, and scale is rendered live from Grand Piano samples — no synthetic loops, no compressed midi. The result is the cleanest, most musical training audio on iOS.

ONE SCORE THAT MEANS SOMETHING: THE COCO PERFORMANCE INDEX (CPI)

Stop guessing if you're improving. CPI is a single, unified metric that rolls up your performance across every game and skill — so you always know exactly where your ear is, where it was last week, and what to train next.

SEVEN GAMES (AND COUNTING): EACH TARGETING ONE SKILL

- Sonar: Pitch identification
- Triad: Chord quality recognition
- Climb: Ascending intervals
- Fall: Descending intervals
- Blend: Harmonic intervals
- Ladder: Scale identification
- Span: Interval comparison
Plus async, daily worldwide challenges to train your ear against real musicians, on your schedule.

SEVEN THEORY COURSES — BUILT INTO THE APP (Coming soon)

Music Fundamentals · Scales & Keys · Intervals · Chords · Chord Progressions · Modes & Advanced Scales · Ear Training Theory.
~66 lessons. 285 slides. 70 final-test questions. Theory and practice are kept separate at the database level — so you can pick exactly what you need, when you need it.

DAILY WORKOUT — 5–15 MINUTES, REAL RESULTS

Coco picks the right exercises for your level every day. "Contrast before similarity" pedagogy means you build solid foundations before you tackle the hard stuff. Most musicians notice the difference within 2–3 weeks.

- Guitarists, pianists, producers, songwriters, vocalists, and DJs
