Library
Connect WebDAV / SMB / NFS / FTP servers, or import local folders. TuneSync builds one library.
Your music, all in one place
Connect a NAS and local folders, then browse, search, and play one personal library. Enrich metadata and lyrics, turn favorite tracks into accompaniment, and polish your takes in the new Recording Studio.
Music shouldn't be spread across half a dozen apps.
TuneSync brings your servers, folders, and player together. Connect once and you're ready.

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
Playback
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
Sing along
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” with a direct path into Recording Studio
Recording Studio
Polish a take into the version worth keeping
After saving a karaoke take, open it directly in Recording Studio. Select the keep range on its real waveform, adjust master volume, and add Studio or Concert Hall ambience. The original stays intact for instant comparison, undo, or restoration.
- Real waveform timeline with precise trim handles
- Master volume plus Studio and Concert Hall ambience
- Original / Edited A/B preview with undo and redo
- Non-destructive save, share, and one-tap restore

User reviews
Feedback from users
“I used to switch between several apps to play my own music. After connecting the NAS, everything is in one place.”
Lin Yifan
NAS user · self-hosted WebDAV
“The AI DJ's auto-continue is genuinely useful — it tops up the queue when it runs low, so I don't have to keep selecting.”
M. Chen
BYOK with DeepSeek
“I didn't expect to remove vocals and sing on my phone. Drop the vocal, sing with the accompaniment, and play it back afterward.”
Kai
Core ML separation
“My library info was fairly disorganized. After one batch organize, the artwork and release years are mostly filled in.”
Zhang Rui
Full-library batch refresh
“I appreciate using my own API key — requests go straight to the model I chose, without any intermediary.”
D. Wang
Self-hosted Ollama
“It found my server on the LAN automatically and connected after a quick setup — easier than I expected.”
