Mosic: Offline Music Player

Your offline music player for MP3, FLAC, and more. No account, no ads. Import via Files or Wi-Fi. Collections remember position — albums and audiobooks stay separate.

Mosic is an offline music player for files you already own. Play MP3, FLAC, WAV, AAC, ALAC, and AIFF locally — no sign-in, no streaming, no ads.

Import tracks or whole folders from the Files app, or upload from a computer or another device on the same Wi-Fi. Organize with collections. Lyrics, favorites, sleep timer, shuffle/repeat, and playback speed — day-to-day listening does not need the internet.

Why Mosic • Truly offline: library, playback, lyrics, and listening stats work without a network • Privacy first: data stays on your device; we don’t collect or upload your library or listening history • No ads, and we don’t push subscriptions just to listen; optional tips in Insights support continued updates without unlocking features • Per-collection playback memory: position, track, speed, and repeat/shuffle stay independent — switch between audiobooks, courses, or albums and pick up where you left off • Format-friendly: MP3, WAV, FLAC, AAC, ALAC, AIFF; lyrics via LRC

Organize your way • Create collections; import files, folders, or use From Other Device • Same Wi-Fi: start receiving on your phone, open the address/QR code in a browser on another device (keep the app in the foreground while uploading) • One song can belong to multiple collections • Custom covers or auto-generated covers • Favorites + one-tap favorite on a track • Sort and search within a collection

Keep collection progress • Each collection independently saves: last track, position to the second, playback speed, and sequential / shuffle / repeat-one mode • Listening to audiobook A, switch to music collection B, then back to A — place and speed are still there • Built for audiobooks, courses, serials, and listening across albums in parallel

Play at your pace • Repeat all / shuffle / repeat one • Sleep timer (by time or end of current track) • Playback speed • LRC lyrics, mini player, background and Lock Screen controls • Insights: total listening time and today

For travel, local libraries, audiobook listeners, and anyone who wants to finish their own files in peace.

Open the app, import a folder (or upload from another device), hit play.
