Linthra is an open-source Android music player for people who keep their music on
their own devices or self-hosted servers. It plays local files, and it streams
from self-hosted music servers such as Jellyfin and Navidrome/Subsonic — you
bring your own server and sign in with your own account.
Linthra is an unofficial community client. It is not affiliated with Jellyfin,
Navidrome, or Subsonic.
The app is still early alpha. It's usable for testing on a real device, but it
isn't production-stable and has a few rough edges. The lists below separate what
works today from what's still planned.
On privacy:
* No ads, no tracking, no analytics, and no crash-reporting or telemetry SDK.
* No account to create, and nothing phones home — streaming is the default, and
downloads only happen when you ask for them (Wi-Fi only unless you opt in to
mobile data).
* When you sign in to a server, the password is used once to get a session
token, then dropped; the token is stored encrypted and never logged.
* Open-source under the Mozilla Public License 2.0, so anyone can read, build,
and contribute to it.
What works today:
* Local library — pick a folder with the Storage Access Framework (no broad
storage permission), scan it, and browse Songs, Albums, and Artists with
search.
* Streaming from your own Jellyfin or Navidrome / Subsonic server: test the
connection, sign in, sync, and play, including over HTTPS.
* A smart offline cache — download tracks for offline play, with a size limit
and a "Keep offline" pin.
* Queue / Up Next, playlists and favourites (synced with Jellyfin where it's
supported), and automatic "smart mixes" built from on-device signals.
* Background playback with a media notification and lock-screen, Bluetooth, and
wired-headset controls, plus shuffle / repeat and synced lyrics.
* Android Auto browsing, and casting to a Chromecast, speaker, or TV through a
pure-Dart Cast implementation (no Google Play Services).
Still to come:
* Reading tags and album art from local files (for now they show file names).
* Subsonic favourites, lyrics, and cover art, and fuller playlist sync.
* "Download all" for an album or playlist.
* More sources, such as WebDAV / NAS, behind the same interface.
* A Linux desktop build later, from the same codebase.
Linthra is distributed for testing as a sideloaded APK from GitHub Releases. It
isn't on F-Droid or Google Play yet.
Versions
Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
