Master the Staff

Treble and bass clef, read at a glance. Three modes, plus adaptive practice that quietly serves up the notes you keep missing. No ads, no account, works offline.

A focused trainer for one skill: naming the note on the staff without counting up from the bottom line.

A note appears, you tap its name — or play it on the keyboard. Three minutes a day is enough to feel your sight-reading speed change.

WHO IT'S FOR • You can read music, but slowly, one line at a time • Treble is fine, bass clef is a struggle • Ledger lines still trip you up • You've just started piano or guitar and want reading to keep up • You want something small to practise between lessons

THREE SESSION MODES • Endless — practise as long as you like • 20 Notes — clear twenty notes as fast and accurately as you can • 60 Seconds — score as high as possible in one minute

ADAPTIVE PRACTICE The app tracks your accuracy for every note and quietly asks the ones you miss more often. The Statistics screen shows accuracy note by note and highlights what to focus on next.

TWO WAYS TO ANSWER • Note buttons — seven pitch buttons, fast and simple • Piano keyboard — answer the exact octave too, when you're ready

TWO DIFFICULTIES • Easy — notes stay inside the staff, no ledger lines • Normal — two full octaves, ledger lines included

ENGLISH AND JAPANESE Pitches are shown as C D E in English and as ド レ ミ in Japanese. Switch any time inside the app.

ALSO • Every correct answer plays the real pitch, so your ear trains alongside your eyes • A miss shows the right note name straight away, on the staff • Best streak and best score are kept per clef • Sound, haptics and keyboard labels can each be turned off • Universal — iPhone and iPad

PRIVACY • No advertising of any kind • No account, no sign-in • No data collected and nothing transmitted • Settings and records stay on your device • Works entirely offline

Three minutes a day. Stop counting lines and start reading music.
