Tonmi: Perfect Pitch for Kids
Piano ear training music games
Free · In‑App Purchases
Perfect pitch is rare in adults, but young children can learn it. Tonmi turns Japan's Eguchi method into a short daily game: hear a piano chord, tap its color.
Perfect pitch is the ability to hear a note and name it instantly. Only about 1 in 10,000 adults has it, but young children can learn it. Tonmi turns the practice into a short daily game your child will ask for.
HOW IT WORKS
Tonmi plays a piano chord. Your child listens and taps the flag that matches the sound. Right answers bring balloons to pop, and each session ends with confetti and a sticker to pick. No note names and no reading, just listening.
THE METHOD
Tonmi follows the first stage of the Eguchi method, taught in Japan for over 30 years: nine piano chords, each with its own color, added one at a time as the earlier ones settle in. In a published study of the method (Sakakibara, 2014), every child who completed the training gained perfect pitch. The children started between the ages of 2 and 6. The skill is easiest to pick up in early childhood and gets harder with age, but older children are welcome too.
WHAT TO EXPECT
Tonmi covers stage one: the nine white-key chords. The black-key chords and single-note stages are not included yet. The study followed a longer, teacher-led program, and Tonmi itself has not been independently tested. Results depend on regular practice and on the child, and no app can guarantee perfect pitch.
MADE FOR LITTLE EARS AND LITTLE HANDS
• No reading needed: play together at first and help when your child needs it
• Big flags, real piano recordings and an instant response to every tap
• Right answers bring balloons your child can pop straight away
• Each session ends with confetti and a sticker to pick
• A sticker book with 84 hand-drawn stickers to fill, page by page
• A calm pace: short sessions with a little pause between sounds
PARENTS SET THE PACE
• A parent corner, locked behind a grown-up question
• You decide how many sessions your child plays in a row, then Tonmi takes a nap
• An ear map for every color, a practice calendar, answer speed and the chords that get mixed up most
• Choose whether new colors arrive carefully or faster
• A short weekly report on Sunday evening, if you allow notifications
• Progress syncs between your devices with iCloud
PRIVACY
No ads. No tracking. No accounts. The listening game works offline once it's installed; purchases and iCloud sync need an internet connection.

New: Tonmi now fits iPhone Duo, folded or open. The welcome pages and the plan screen have a fresh look, and if you close the plan screen, your child can play one full round for free. When your child reaches a milestone, you can share a small card from the parent corner. It's made on your phone, with no name or photo. Got a code from a friend or a teacher? Tap "I have a code". You can now also change your plan inside the app. Bug fixes.
