Extensions
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 Store tab in the app
- On first launch, enter an Extension Repository URL when prompted
- Browse and install extensions with one tap
- Or download a
.spotiflac-extfile and install manually via Settings > Extensions - Configure extension settings if needed
- Set provider priority under Settings > Extensions > Provider Priority
Developing Extensions
Note

Development
SpotiFLAC Mobile combines a Flutter/Dart UI, a Rust backend from
rust_backend/, and thin Android/iOS platform bridges. Android
Gradle builds the Rust native artifacts automatically. Tool versions are pinned in
rust_backend/rust-toolchain.toml and
rust_backend/Cargo.lock.
Start with the Contributing Guide for the development setup, project boundaries, validation commands, and pull request checklist.

FAQ
Why does the Store tab ask me to enter a URL?
Starting from version 3.8.0, SpotiFLAC Mobile uses a decentralized extension repository system. Extensions are hosted independently rather than on a built-in server, so anyone can create and host a compatible repository. Enter a repository URL in the Store tab to browse and install extensions.
Why is my download failing with "Song not found"?
The track may not be available from your enabled providers. Try enabling more providers under Settings > Extensions > Provider Priority, or install additional download extensions from the Store.
Why are some tracks downloading in lower quality?
Quality depends on what's available from the source and the installed download extension. Check each extension's quality options and service notes in the app.
Can I download playlists?
Yes! Just paste the playlist URL in the search bar. The app will fetch all tracks and queue them for download.
Why do I need to grant storage permission?
The app needs a writable destination for downloaded files. On Android, choose a folder with the system folder picker (SAF), or use the app-specific folder. If Android revokes a saved folder grant, select the folder again in Settings.
Is this app safe?
SpotiFLAC Mobile is open source, so its code and build workflows can be inspected directly in this repository.
Why is downloading not working in my country?
Some countries have restricted access to certain streaming service APIs. If downloads are failing, try using a VPN to connect through a different region.
Can I add SpotiFLAC Mobile to AltStore or SideStore?
Yes! Add the official source to receive updates directly within the app. Copy this link:
https://raw.githubusercontent.com/spotiflacapp/SpotiFLAC-Mobile/refs/heads/main/apps.json
In AltStore/SideStore, go to Browse > Sources, tap +, and paste the link.
