Learning piano on your own? Photograph printed sheet music and the app reads it on your device (no account, no upload). See note names, hear them read aloud, or listen on a piano.
IMPORT YOUR MUSIC
- Scan with the camera (perspective correction, multiple pages), or pick from Photos or Files (PDFs, images)
- Printed piano scores (grand staff) become playable music on your device
- The printed tempo is read too (M.M. = 120, Allegro, rit., accel.)
- Premium's latest recognition model also reads dynamics, hairpins, and pedal marks; pick the previous version in Settings
- Re-read earlier scores by touching and holding them in the Library (the latest model needs Premium)
REVIEW AND FIX THE RESULTS
- Turn on Settings → Review recognition results to check uncertain notes one by one beside the image
- Fix pitches and durations, add or remove notes, and finish your review later
- After importing, fix notes, rests, chords, measures, key, time signature, dynamics, pedal, and tempo changes per measure in Edit
- Tap the original image for full screen, zoomed in on the selected note
READ MUSIC FASTER
- Note names on every note (C D E, Do Re Mi, or Japanese note names)
- Read aloud with a different voice for each hand; chords from the lowest note up
- Choose voices, speech speed, and app language (20 languages) in Settings
HEAR HOW IT GOES
- Start at the score's own tempo (100%), then slow down or speed up, with dynamics, pedal, and tempo changes (rit., accel.)
- Sounds: built-in upright, or download a grand piano. Concert grand piano with Premium
- Play one hand only, loop A to B (saved per score), and follow along on the score
COMPARE WITH YOUR PLAYING
- Play a video of your playing (keys and hands) beside the score, including ones from Photos
- Match one spot to the score, and the score follows the video, with the score's sound if you like
- Videos are stored only on this device
LIBRARY AND PRACTICE TIME
- Scores on a bookshelf with covers; search by title and sort. Resume where you left off from Home
- Time your practice; the timer shows on the Lock Screen and in the Dynamic Island
- Add time manually; look back with weekly, monthly, and yearly charts by score
FREE TO USE, WITH ADS
- CPianoS is free, with ads in the Library and on the Import screen
- 1 in 5 times you open a score, a short ad appears that you can close right away
- Import up to 3 pages at a time without ads; from the 4th page, each ad you watch reads 2 more pages (internet required)
