Open-source, local-first music player for music you own. No forced sync.
About this app
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.

Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be io.github.thezupzup.linthra is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.1.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Linthra first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Linthra, and a listing is removed when the evidence for it stops holding up.
