flacidal-core/ Shared Go backend (compiled as .so/.a)
The Go backend handles all networking, downloads, metadata, and storage. Flutter handles the UI. Communication is via JSON-RPC over FFI.
Requirements: Flutter 3.41+, Go 1.23+, Android NDK r29
# 1. Build Go shared libraries
cd flacidal-core
make android-arm64
make install-android
# 2. Build Flutter APK
cd ../flacidal-mobile
flutter build apk --releasecd flacidal-core
make ios
make install-ios
cd ../flacidal-mobile
flutter build ipa --no-codesign| Setting | Default | Options |

Do I need a Tidal account? No. FLACidal handles authentication internally.
Where are files saved?
/storage/emulated/0/Music/FLACidal/ on Android. Configurable in Settings.
Is iOS supported?
The codebase compiles for iOS but we don't have a contributor to handle Apple signing yet. You can build locally with flutter build ipa --no-codesign and sideload via AltStore/SideStore. Contributors welcome!
Does it work in the background? Yes. A foreground service keeps downloads running when the app is minimized.
Contributions are welcome! Areas where help is especially needed:
- iOS build & signing — We need a contributor with an Apple Developer account to set up code signing, TestFlight distribution, and the AltStore source. The Flutter + Go FFI codebase already compiles for iOS.
- Bug reports — Open an issue with steps to reproduce.
