Built for big lossless libraries

Gleo started from the look of Wora and fixed what kept getting in the way: real seeking, a real queue, no gaps, and a library that stays fast.

Sound

  • Gapless playback and exact seeking in every format, even high-res FLAC with no seek table.
  • Bit-perfect output with WASAPI exclusive mode on Windows, and a verified badge in the signal path.
  • A 10-band graphic EQ and an advanced parametric EQ with presets; EQ per output device.
  • Headphone correction from AutoEQ or Equalizer APO files, plus crossfeed.
  • Upsampling with soxr, ReplayGain, and Best quality on this device.
  • Optional crossfade (never inside a gapless album) and trim silence.

Library

  • Fast background scanning of several folders; albums, multi-disc sets and Various Artists grouped right.
  • CUE sheets: one big file plus its .cue shows as separate songs.
  • Smart playlists, star ratings, Browse by genre, year and composer, and Statistics.
  • A duplicate finder that only hides copies; it never deletes files.
  • Back up & restore in one .gleobackup file, even between Windows and Android.
  • Lyrics: synced .lrc files or tags, and optional downloads from LRCLIB.

Looks

  • A CD or vinyl slides out from behind the cover and spins while the music plays.
  • Disc mode and an always-on-top mini player on Windows.
  • Cover art packs for albums with no good cover: public-domain paintings, storybook illustrations, or painted styles.
  • Android: a lock-screen disc view and a home-screen widget.
  • Windows: taskbar buttons, media keys, the media overlay and a tray icon.
  • Dark and light themes; the accent follows the album art.

Privacy

  • No AI. Suggestions come only from what you play in Gleo.
  • No account and no sign-in.
  • Nothing is sent unless you switch it on: the update check and LRCLIB lyrics are both off by default.
  • Your music files are only read, never changed. Cover picks live in Gleo, not in your files.

Plays FLAC (any resolution), ALAC, WAV, AIFF, WavPack, APE, DSD, MP3, AAC, OGG and Opus. What's new in 0.4.1

Coming from Lumen?

Gleo is Lumen's new name, from 0.4.0.

Windows: Gleo installs beside Lumen. On its first start it copies your Lumen library, playlists, play counts, settings and cover picks. Lumen's folder is kept; once Gleo looks right, uninstall Lumen yourself.

Android: Gleo is a new app, so it can't update the Lumen test app. Uninstall Lumen first, then install Gleo. The phone starts fresh (the Lumen test app had no backup); from now on use Settings → Data and updates → Back up.

FAQ

Questions

Something else? Open an issue or write to capsuleutkarsh@gmail.com.

Which Android APK do I need?
  • arm64-v8a: almost every phone from the last several years. Start with this one.
  • armeabi-v7a: older 32-bit phones. Use it if Android says the arm64 APK isn't compatible.
  • x86_64: emulators and other x86 devices.

Gleo needs Android 8 or newer. All three are under All downloads, with SHA256SUMS-android.txt to check them.

Android or Play Protect warns me about the APK

Gleo isn't on the Play Store yet, and this beta is signed with a temporary test key, so Android asks before installing it and Play Protect may offer to scan it or call it unknown. Allow installs from your browser or file manager, and if Play Protect stops you, open More details and choose to install anyway (the wording differs between phones).

When Gleo moves to its permanent key, you will uninstall once and reinstall. Back up first with Settings → Data and updates → Back up.

Windows says "Windows protected your PC"

That is SmartScreen. The installer isn't signed with a paid code-signing certificate, so new downloads get this warning. Click More info, then Run anyway. You can check the file against SHA256SUMS.txt in the release. Prefer no installer? Use the portable .zip.

Where does Gleo keep my data?
  • Windows: %APPDATA%\Utkarsh Tripathi\Gleo\ holds the library list, playlists, favourites, play counts, sound settings and the log. Settings → Data and updates opens it. Cover thumbnails are in %LOCALAPPDATA% and are safe to delete.
  • Portable: a userdata folder next to gleo.exe.
  • Android: inside Gleo's own app storage. Uninstalling removes it, so make a backup first.

Uninstalling on Windows asks whether to delete your data; the answer is keep unless you choose otherwise.

Will Gleo change my music files?

No. Gleo only reads your files. Ratings, cover picks and play counts are kept in Gleo's own data.

Is it really free?

Yes. Gleo is free to use and share under the UT Community Licence 2.0. It is not for sale; if you change it, keep the credits and send your changes back.
