Reading sheet music isn't a gift — it's a skill built from short, repeated doses. Cléo cuts it into two-minute lessons you can do standing on a train, with no instrument and no gear.

Cléo is an iPhone app that teaches sheet music reading, in English and French. The course covers eight chapters, from the staff to key signatures, in two-minute lessons. It is entirely free; an optional subscription removes the ads. The app requires no account, no microphone, and no instrument.
Not mockups: the app exactly as it runs on an iPhone.
Why a notehead is hollow or filled, why a stem flips direction halfway up the staff, why a second clef exists at all. Here's what you'll be able to do by the end of the eight chapters.
The five lines, the four spaces, and everything that spills past the staff — in treble clef and bass clef alike.
Whole, half, quarter and eighth notes, dots and ties. Position tells you the pitch, shape tells you the time.
Whole, half, quarter and eighth rests — and why silence gets written down instead of left blank.
Bar lines, time signatures and what those two numbers actually mean, on examples you can count through.
Sharps, flats, naturals, and the key signature at the start of the staff that settles the whole piece at once.
Not just the rule: the reason for it. That's the difference between revising something and remembering it.
Three more screens, untouched.
No account, no server: everything happens on your iPhone.
The first chapter starts at the five lines of the staff. If you already read music, a placement test opens the chapter where it stops being obvious.
The rule gets explained, then you get asked about it. Enough to fit the wait on a station platform rather than a practice session.
The daily mission, the streak and adaptive-difficulty training keep your reading fresh between chapters.
All eight chapters, all 37 lessons and every exercise, with no exceptions. The subscription unlocks no content: it removes the ads and the lives.
The complete course, no exceptions. Limited lives, an ad now and then, and an optional video to earn a life back.

Download on the App StoreYes. Reading a score and playing an instrument are two separate skills. Cléo teaches reading only: recognising notes, durations, rests and bars. Everything is done by tapping the screen, with no instrument and no gear.
No. The app never asks for microphone access and never listens, at any point. Exercises are answered by tapping the screen, one-handed.

No. The first chapter starts from the five lines of the staff and assumes nothing. If you already read music, a placement test finds what you know and opens the chapter where it stops being obvious.
About two minutes. The course has eight chapters and 37 lessons, built to fit the wait on a station platform rather than a practice session.
