## Description

CelloDex helps cello players of all levels practice more effectively by scanning sheet music and displaying precise cello fingering information.<br><br>Scan &amp; Play<br>Take a photo of any printed sheet music, and CelloDex instantly shows you which string to play on, which finger to use, and which position to be in.<br><br>Smart Fingering Guide<br>- Automatic string assignment (A, D, G, C strings)<br>- Finger numbers (0-4) for every note<br>- Position indicators (1st through 7th position)<br>- Prefers lower positions for easier playing<br><br>Built-in Practice Library<br>- Open string exercises<br>- Position reference charts for all 4 strings (1st-7th position)<br>- Suzuki-level progressive exercises (Vol. 1-5)<br>- Search, filter by string/category, and save favorites<br><br>Sheet Music Display<br>- Beautiful rendered notation powered by OpenSheetMusicDisplay<br>- Position labels overlaid on the score<br>- Detailed note list view with string, finger, and position info<br><br>Recognition Engine<br>CelloDex reads your score with KHEngine, our own optical music recognition server. It is selected by default and handles printed sheet music.<br><br>A ChatGPT (OpenAI) engine is also available as a backup, and CelloDex switches to it automatically if the KHEngine server cannot be reached, so your scan still goes through. Results from the backup engine are less reliable — check them against your score.<br><br>Recognition works best on clear photos of printed music, one page at a time. Handwritten scores are not reliably supported.<br><br>Perfect for:<br>- Beginner to intermediate cello students<br>- Self-taught cello players<br>- Cello teachers preparing lesson materials<br>- Quick fingering reference during practice<br><br>Start practicing smarter with CelloDex!
