Zeb Tunes

Zeb Tunes is an offline-first, mobile music player. It ships with a built-in catalogue of four synthesized, playable tracks (rendered in the browser, no network) and uses IndexedDB to keep everything on-device. Create a local account, upgrade to artist, and upload your own audio right from your phone; listeners can favorite and save any track for offline playback. A full now-playing screen, a mini player bar, both portrait and landscape layouts, and a service worker for true offline use.
