Your music. Your server.
No compromises.

Aetherfin streams from your self-hosted Jellyfin or Navidrome server — or plays local files from your device. Decodes everything on-device with libmpv. FLAC, ALAC, OPUS, WAV — bit-for-bit. No transcoding, no telemetry, no cloud.

Everything you need, nothing you don't

A premium music experience that happens to be open source.

Real-time visualizer

64-band FFT spectrum from actual audio output, rendered at 60 fps. No microphone permission needed.

Gapless playback

libmpv pre-fetches the next track in the background. Seamless album-side transitions.

86-effect DSP rack

18-band EQ with presets, compressor, echo/delay, phaser, flanger, chorus, pitch shift, loudness normalization, and more. Master bypass switch.

Synced lyrics

LRC parsed on-device with auto-scrolling highlight. Displayed on your lock-screen too.

Jellyfin + Navidrome + Local

Works with both servers out of the box, or play files straight from your device. No server required for local mode.

Bit-perfect output

Force sample rate, bit depth, exclusive mode. Lossless FLAC, ALAC, OPUS, WAV — no quality loss.

Sleep timer

Presets from 5 to 60 minutes, plus an "end of track" mode that pauses when the current song finishes.

Privacy first

No analytics. No ads. No trackers. No Aetherfin servers. The app talks only to the server you configure.

A glimpse

Spectral colors from your cover art. Premium typography. Quiet motion.

Three steps to music

  1. 1

    Download the APK

    Grab the latest release. Universal APK works everywhere, per-ABI builds are smaller.

    Latest release →
  2. 2

    Choose your mode

    Connect to a Jellyfin/Navidrome server, or pick a folder of local music files. No server needed for local mode.

  3. 3

    Play something

    Tracks stream as raw bytes from your server, or play directly from device storage. Your CPU stays cool either way.

Your music deserves better.

No cloud middleman. No subscription. No analytics. Just a polished player that respects your library and your privacy.
