Your repertoire is the curriculum. Most music apps drill you on exercises you'll never play. Real Sight Reader flips that: import the MusicXML scores you're actually working on, and the app turns them into focused reading and rhythm practice — so every minute you spend here pays off in the pieces you care about. IMPORT YOUR OWN MUSIC Bring in any MusicXML (.xml / .mxl) score and practice straight from it. Or start with the bundled library of public-domain classics — Bach inventions, Chopin preludes, Joplin rags, Mozart, and more. TAP THE RHYTHM Sample-accurate rhythm training with a real metronome feel. Tap along as the playhead moves; on-time taps score green, rushing or dragging shows up instantly. Per-device latency calibration keeps scoring honest on any headphones or speaker. READ BOTH CLEFS Drill the two-hand note pairs in a piece — treble and bass together — and see exactly which pairs you read fast and which slow you down. Practice the weakest ones in a focused set. PRACTICE THE WAY READING ACTUALLY WORKS - Listen and repeat: hear a phrase, then play it back from memory. - Eye-hand span: train reading ahead of where you're playing. - Weak-figure drills: the app surfaces the rhythms you keep missing and drills just those. PLAY ALONG WITH MIDI Connect a MIDI keyboard and play the rhythm or the melody — the app scores your timing and your notes. SEE YOUR PROGRESS Per-figure and per-pair stats show your accuracy and timing trend over time, weakest first, so you always know what to work on next. A daily streak and home- and lock-screen widgets keep you coming back. CHALLENGE A FRIEND Finish a run and share a challenge link or a designed brag card with your score — they can try to beat it. PRIVATE BY DESIGN Your scores and your progress stay on your device. No account required. Real Sight Reader is for pianists, students, and teachers who want their practice time to land on the music in front of them.

Clef: Sight Reading Trainer Connect written notes, note names and piano keys through short, repeatable drills. Choose your reading level and session length, then start practising. New beginners start with a small group of C-position notes and patterns. Short explanations introduce unfamiliar concepts, and help stays available during practice. Spaced repetition uses your answers to schedule what to revisit. READING - Note Naming: treble and bass - Grand Staff: alternate between treble and bass - Ledger Notes: notes above and below the staff - Intervals: the distance between two notes - Key Signatures: sharps and flats AT THE KEYBOARD - Keyboard Mapping: find the named note - Five-Finger Patterns: repeat short patterns and read-and-play exercises - Triads and Inversions: recognise and play chord shapes - Seventh Chords: practise four-note chords - Major and Minor Scales: follow note patterns and fingering guides - Arpeggios: practise broken chords - Hands Together: coordinate paired notes Fifteen focused practice tracks, with daily mixed sessions and individual drills. PLAY ON SCREEN OR WITH MIDI Use the on-screen piano and answer buttons, or connect a compatible MIDI keyboard. Follow the note and register instructions for each drill. Note names can use letters or do-re-mi. For played patterns, “Watch & listen” demonstrates the exercise; “Your turn” returns to practice. Clef checks the notes you enter. Fingering guides are references, not a measurement of your physical technique. SHORT SESSIONS, USEFUL FEEDBACK Choose three or five minutes, then continue practising from the results screen when you want to keep going. Review your answers, clean recall and best run, with an estimated recall forecast for the items practised in that session. Adjust your reading level, session length and practice goals in Settings. Paper, ink and a single gold accent keep the focus on the music. Practice history stays on your device. No account is required. FREE AND FULL ACCESS Treble and bass focused reading practice and one mixed daily session per calendar day are free. Full access is available through annual or monthly subscriptions, or a one-time lifetime purchase. Prices and any eligible introductory offer are shown before purchase. Existing owners of the earlier one-time unlock retain their access.
