✨Features
Everything you need to build a high-quality music library on your phone.

True Lossless FLAC
Download in up to 24-bit/192kHz quality. No transcoding, no quality loss. Pure studio-grade audio files.

Multiple Providers
Download from Tidal, Qobuz, Deezer, and more via extensions. Automatic fallback if a source is unavailable.

Extensions
Community-built extensions add new music sources and features. Install from the built-in Store with one tap.

Search by Link or Name
Paste a Spotify, Tidal, Qobuz, or Deezer link. Or just search by song name — it handles the rest.

Batch & Playlist Download
Download entire albums and playlists at once. Smart queue management with concurrent downloads.

Rich Metadata
Full metadata embedding — album art, lyrics, genre, label, copyright, and more. All embedded in the FLAC file.

Extensions let the community add new music sources and features without waiting for app updates. When a streaming service API changes or a new source becomes available, extensions can be updated independently.

➠ Installing Extensions
Open the “Repo” (Store) tab in the app
Enter https://github.com/zarzet/SpotiFLAC-Extension/tree/main/extensions into the “Repository URL” and press on “Add Repository” button
Browse and install extensions with one tap
Or download a .spotiflac-ext file by clicking on it and pressing on “Raw” button and install manually via “Settings” tab > “Extensions”
Enable extensions under “Settings” tab > “Extensions” > “Installed Extensions”
Configure extension settings if needed
Set provider priority under “Settings” tab > “Extensions” > “Provider Priority”
