Features

One app. Three senses.

Everything you need to learn piano, practice with feedback and enjoy playing.

Talk to your coach

A natural, real-time voice conversation. Ask anything about technique, theory or what to practice next, hands-free while you play.

Hand tracking

Your camera watches your hand shape and wrist in real time and tells you when to relax or curve your fingers.

Listens to your piano

Play a real acoustic or digital piano. Opttonia hears the notes and checks them against the lesson.

500+ guided lessons

From Middle C to two hands together, step by step, with a solfège guide (Do, Ré, Mi) built in.

Scores and play along

Import MIDI, PDF, Word or text files, watch the notes light up and follow along on the keyboard.

Mood loops

Generate calming music for Sleep, Focus, Workout or Relax in one tap, then play over it.

And more

Small details that keep you playing

Practice reminders

Pick a daily time and get a gentle nudge so practice becomes a habit.

Piano Keys explorer

Tap any key to hear it and see its name, or play the Find the Note game.

English and French

Interface, lessons and voice coach in both languages, including solfège names.

Privacy first

Hand tracking runs on your device and you control your data.

Adaptive coaching

Your coach adjusts to your level, from complete beginner to confident player.

Short sessions

Ten focused minutes a day are enough. Pick up exactly where you left off.

How it works

From first note to first song

01 / 05

Meet your coach

Open the app and your coach greets you. Chat by text or tap the mic. Quick actions jump straight to Piano Keys, Lessons, Camera, Listen, Play Along, Score and Loops.

02 / 05

Speak out loud

Switch to live voice. The neon rings pulse as your coach listens and answers, so you can keep your hands on the keys.

03 / 05

Show your hands

Point the camera at the keyboard. Opttonia tracks every joint and warns you about a low wrist or flat fingers before bad habits settle in.

04 / 05

Follow the path

Lessons unlock one after another, from Meet Middle C to playing with both hands, with clear goals for each step.

05 / 05

Play along with scores

Open a score, press play and watch the keys light up. Slow it down, loop a bar, then play it yourself.
