Features
Library, playback, organizing, and singing along — together in one app.
Access your NAS music on your phone
On the same network, TuneSync automatically discovers your media server — configure once and you're connected. Choose which folders to index; playback begins as soon as indexing completes.
- WebDAV / SMB / NFS / FTP / DAAP protocols
- Bonjour auto-discovery of LAN servers
- Folder-level indexing — only what you choose
- Mix local folders and remote servers in one library
Lyrics highlight line by line as the song plays
The player scrolls lyrics in time with playback and highlights the current line — tap any line to jump there. The background color is sampled from the artwork, and you can switch to plain-text reading mode when no timing is available.
- Full-screen / mini-player, switch anytime
- Synced lyrics: auto-scroll, tap-to-seek, drag-to-browse
- Queue, loop, shuffle, speed, AirPlay
- Sleep timer and background playback
Remove the vocal, sing with the accompaniment
TuneSync splits a track into vocal and accompaniment stems on your device, with independent volume for each. Lower the original vocal, keep the accompaniment, and sing along — the microphone records your performance in sync. The first separation takes a moment; results are cached for reuse.
- On-device Core ML separation (MDX / DTTNet)
- Live vocal-level control with a 3-2-1 countdown
- Mic recording with input/output latency compensation
- Saves to “My Recordings” for playback and sharing
Use your own key with your preferred model
Enter your own API key to get started — OpenAI, Anthropic, Gemini, Zhipu, DeepSeek and others are preconfigured, or specify a custom endpoint or local Ollama. The AI DJ continues your queue based on your listening habits, and can tidy up irregular file names.
- 40+ provider presets + custom OpenAI-compatible endpoints
- Instant / reasoning model roles, auto-selected per task
- AI DJ with three autonomy levels: preview / one-tap / auto-continue
- Tool calling: web search, album art, lyrics, playback and playlist control
Fill in artwork, year, and lyrics in one pass
TuneSync compares across iTunes, MusicBrainz, and other sources to fill in missing artwork, release years, and track numbers. Works per track, per album, or across the whole library. When sources conflict, your configured weights decide.
- iTunes / MusicBrainz / AI multi-source matching
- Track / album / artist refresh + batch organizing
- Source weights and per-field “overwrite” policies
When you're not sure what to play
Home aggregates charts from several platforms. When you don't have a specific track in mind, TuneSync offers recommendations based on your listening history. Hear a song you like? Open recognition to identify it.
- Apple Music / Bilibili / YouTube / Last.fm multi-source charts
- Suggestions based on what you usually play
- ShazamKit recognition with browsable history
