Numgye: Music Page Turner

Numgye is a sheet music reader that turns pages for you — automatically, hands-free, no Bluetooth pedal required.

Set your tempo, and Numgye's red bar follows your playing measure by measure, turning the page exactly when you need it. AI detects measures in any PDF score, entirely on-device.

AUTOMATIC PAGE TURNING
No more awkward page turns during performances. Numgye follows your tempo with a moving red bar that highlights the current measure, then seamlessly turns the page when you reach the end.

AI-POWERED MEASURE DETECTION
Import a PDF and Numgye's on-device AI instantly detects measure boundaries — no internet required. Fine-tune with easy manual editing if needed.

BPM SYNC & VISUAL METRONOME
Set your tempo from 20 to 300 BPM with a dial, slider, tap tempo, or direct input. The red bar moves across each measure at your exact tempo, giving you a built-in visual metronome.

SETLIST MODE
Organize multiple scores into setlists for rehearsals, worship sets, or concerts. Play through your entire setlist without stopping.

DESIGNED FOR TABLETS
Purpose-built for tablet screens. Crisp PDF rendering, smooth page transitions, and a clean interface that stays out of your way while you play.
