## What is CPianoS?

Learning piano on your own? Turn your printed sheet music into something you can see, hear, and practice with.

Take a photo of a page and the app reads the score for you. Then show the name of every note, have the notes read aloud, or listen to the music played on a piano. Everything is recognized on your device, so there's no account to create and nothing to upload.

IMPORT YOUR MUSIC
- Scan pages with the camera (automatic perspective correction, multiple pages in a row)
- Pick images from your photo library
- Open PDFs and images from Files
- Printed piano scores (grand staff) are converted into playable music on your device

REVIEW AND FIX THE RESULTS
- Notes the app isn't sure about are shown one by one, next to the original image
- Change pitches and durations, or add and remove notes
- Save your review and pick it up later

READ MUSIC FASTER
- Show note names on every note (C D E, Do Re Mi, or Japanese note names)
- Hear note names read aloud ("C sharp", "B flat"...), with a different voice for each hand; chords are read from the lowest note up
- Choose the voices and the speaking speed in Settings

HEAR HOW IT GOES
- Slow down or speed up the tempo
- Play the right hand or left hand only
- Loop a passage from A to B to work on the hard parts
- Save up to two loops per score
- Follow the current position right on the score

YOUR LIBRARY
- Keep your scores on a bookshelf with covers
- Search by title and sort
- Jump back to where you left off, right from Home

TRACK YOUR PRACTICE TIME
- Time your practice with a timer that stays visible on the Lock Screen and in the Dynamic Island
- Forgot to start the timer? Add practice time manually
- Look back on your practice history with weekly, monthly, and yearly charts by score

PRIVACY
- No account required
- Your score images, recognition results, and practice history stay on your device
- Recognition and read-aloud run on your device and are never sent to the developer

GOOD TO KNOW
- Recognition works with printed piano scores (grand staff). Handwritten music and scores for other instruments are not supported.
- Depending on the print quality, lighting, and how busy the score is, some notes may be misread. You can review and fix the results before you practice.
- Please use imported scores for your own personal practice and respect the copyright of sheet music.
- Read-aloud uses the voices installed on your device.

Put your iPhone or iPad on the music stand and start today's practice.
