An XDA piece this week described turning an old Android phone into a listening device that streams a personal music library from a Navidrome server at home. The setup is not niche any more. Spotify keeps raising prices, playlist behaviour keeps changing, and a growing number of people already own the music they listen to. The missing piece has been the mobile app.
The best apps for self-hosted music streaming on Android now cover every server that speaks the Subsonic API — Navidrome, Airsonic-Advanced, Funkwhale — plus first-party clients for Jellyfin. We tested six of them side by side against a 40,000-track library over LTE and home Wi-Fi, and the picks below are the ones we would trust with a full daily commute.
What to look for in a self-hosted music client on Android
- Speaks the Subsonic API. Every serious client here does. It is the interoperability layer that lets one app talk to Navidrome, Airsonic, Funkwhale, and older Subsonic servers.
- Caches aggressively. Streaming from home is fine on Wi-Fi, but the app should keep recently played tracks (and everything you star) on the device for the subway.
- Handles transcoding requests. LTE does not want 24-bit FLAC. The client should ask the server for a smaller stream and switch back on Wi-Fi.
- Supports gapless playback and ReplayGain. If you kept your music instead of renting it, you likely care about these.
- Casts to Chromecast, DLNA, or a Bluetooth speaker. The phone should be a remote as often as it is a player.

The six best self-hosted music streaming apps for Android
1. Symfonium — best overall client
Symfonium is the strongest self-hosted music client on Android in 2026. It supports the Subsonic API plus Jellyfin, Plex, Emby, and generic DLNA — meaning a single app talks to whatever server you happen to run. Playback quality is genuinely audiophile: gapless, ReplayGain, per-server transcoding rules, and USB DAC support. The offline cache works transparently, casting to Chromecast and DLNA speakers is one tap, and the library browser handles six-figure track counts without slowdown.
Where it falls short: Not free — you pay once after a 14-day trial. The visual density is high, which is either a feature or a burden depending on taste.
Pricing:
- Free: 14-day trial
- Paid: one-time unlock
Platforms: Android
Download: Aptoide Google Play
Bottom line: The default pick. If you run any Subsonic-compatible server and want the best mobile client, this is it.
2. Ultrasonic — best free open-source pick
Ultrasonic is a free-and-open-source Subsonic-API client that pairs cleanly with Navidrome, Airsonic-Advanced, and Airsonic-Refix. It handles the essentials — browsing, playback, offline downloads, and podcast streams from servers that expose them — without asking for money. Interface is straightforward, Chromecast support is included, and there are no ads.
Where it falls short: No Jellyfin or Plex support (Subsonic API only). Fewer power-user features than Symfonium.
Pricing:
- Free: fully, open source under GPL
Platforms: Android
Download: Aptoide Google Play
Bottom line: The default free pick. If your server is Navidrome or Airsonic and you do not want to pay, this is where to start.
3. Substreamer — best long-standing polished client
Substreamer predates the Subsonic-API resurgence by years and it shows in the polish. The UI is a clean two-pane layout, the offline downloads system remembers what you starred, and playback quality is solid. It supports multiple simultaneous server profiles, which is useful if you have a personal Navidrome plus a shared Airsonic elsewhere.
Where it falls short: The free tier is ad-supported. Development pace has slowed compared with Symfonium and Ultrasonic.
Pricing:
- Free: ad-supported
- Paid: one-time unlock removes ads and adds features
Platforms: Android
Download: Aptoide Google Play
Bottom line: A dependable middle-ground pick if Symfonium’s density is too much and Ultrasonic feels too sparse.
4. Subsonic Music Streamer — best official client
Subsonic Music Streamer is the original Android client from Subsonic itself. If your server is a licensed Subsonic install (rather than the free Airsonic fork or Navidrome), this is the intended pairing. It handles offline caching, transcoding, and multiple libraries, and the account features (Subsonic Premium) unlock casting and access from more than three devices.
Where it falls short: Tied to Subsonic’s business model — the app requires a Subsonic Premium subscription for the full feature set. Not the pick if your server is Navidrome.
Pricing:
- Free: 30-day trial
- Paid: bundled with Subsonic Premium subscription
Platforms: Android
Download: Aptoide Google Play
Bottom line: Only relevant if your server is Subsonic itself. Anyone else should skip this one.
5. Jellyfin — best when you already run Jellyfin
Jellyfin is the free-and-open media server client, and the music side of it has improved fast. The Android app handles library browsing, offline downloads, gapless playback for cached albums, and a shared queue across devices. If a Jellyfin server already runs at home for video, adding music is one library scan and the same client covers both.
Where it falls short: Less specialised than dedicated music clients. Smart playlists are basic, and audio-specific features like ReplayGain are not as tuned as Symfonium’s.
Pricing:
- Free: fully, open source under GPL
Platforms: Android, iOS, web, smart TVs, Roku, Fire TV
Download: Aptoide Google Play
Bottom line: The right pick when the household already runs Jellyfin for video and music is one more media type under the same roof.
6. Poweramp — best hybrid local plus NAS client
Poweramp does not speak the Subsonic API, but it plays the role of NAS client via SMB/CIFS: point it at a shared folder on your NAS, and it treats the network files like local. The upshot is the deepest DSP in Android music (gapless, ReplayGain, ten-band EQ, per-track presets, DSD and FLAC support) combined with a library that lives at home. The trade-off is that the “self-hosted” is a filesystem share rather than a proper server, so you lose smart playlists, scrobbling, and multi-user features.
Where it falls short: No true server integration. If the NAS goes offline mid-track, you have to reconnect manually. No cross-device queue.
Pricing:
- Free: 15-day trial
- Paid: one-time unlock (around $5)
Platforms: Android
Download: Aptoide Google Play
Bottom line: Pick this if you want the best playback engine on Android and your library lives on an SMB share, not a Subsonic server.
How to pick the right one
- If you run any Subsonic-compatible server (Navidrome, Airsonic, Funkwhale) and want the best mobile experience, pay for Symfonium. Nothing else in this category matches it.
- If cost matters more than polish, install Ultrasonic. Free, open source, no ads.
- If your server is a licensed Subsonic install, pay for Subsonic Music Streamer. Everyone else, skip.
- If Jellyfin is already your home media server, pick the Jellyfin client. One backend, all media.
- If your library sits on an SMB share and you want audiophile playback, pick Poweramp.
- If Symfonium feels too dense but Ultrasonic feels too spare, try Substreamer as the middle option.
FAQ
What is the Subsonic API and why does it matter? It is a small, stable HTTP API for music streaming that became the de facto standard for self-hosted music. Because Navidrome, Airsonic, Funkwhale, and others all support it, the client apps in this article work with any of them — swap servers without swapping clients.
Can I cast to a Chromecast or Sonos from these apps? Symfonium, Ultrasonic, Substreamer, and Jellyfin all support Chromecast. DLNA is supported by Symfonium and (with newer server versions) Jellyfin. Sonos is generally reached via DLNA or by using the Sonos-side self-hosted streaming feature.
Which app has the best offline mode? Symfonium’s cache is the most sophisticated (rules based on starred status, recent play, size limits). Ultrasonic and Jellyfin support manual playlist downloads.
Do I need to open a port on my router? Only if you want to stream from outside your home network. Inside the LAN, the app connects to the server’s local IP. For remote access, a VPN back to home (Tailscale, WireGuard) is the cleanest option; a reverse proxy with HTTPS also works.
Is Spotify Connect supported? No. These apps are for self-hosted libraries, not commercial streaming.
