Musicians cannot easily view and perform sheet music on mobile devices during practice and performance

Musicians using LilyPond (a professional music notation software) have no straightforward way to view their sheet music on iPhones and iPads, forcing them to either print physical copies, use clunky workarounds, or switch to less powerful notation software. This creates friction in modern practice workflows where musicians expect seamless mobile access to their scores, especially for rehearsals, gigs, and remote collaboration.
