StageMate is a sheet music reader for iPhone, iPad and Android phones and tablets. Musicians import their own PDF or image scores or scan with the camera, annotate (Apple Pencil on iPad), organize setlists, use a tuner and metronome, and turn pages with blink or head movements using the front camera. Gesture reliability depends on lighting, camera placement and posture, so test before performing.
Core features are free with no payment required, up to 3 setlists and 5 score-extraction uses per month. Optional Pro is US$11.99 per year or $1.99 per month, and Lifetime is US$39.99 once; Pro adds iCloud sync (Apple devices only) and unlimited setlists. Prices are for reference, so check the purchase screen. Apple and Android libraries are separate.
The goal behind StageMate is to help musicians keep their own scores organized and reduce interruptions while reading and playing.
