Description

An open-source Syncthing client for iPhone and Android, powered by the Syncthing daemon via gomobile.

Syncthing's official Android client was archived in December 2024. No single client ran on both phones from one codebase, so this one was built. The daemon runs in-process via gomobile, with a React Native UI scaffolded from react-native-go.

Differences from other clients:

Daemon runs in-process on Android. The Go daemon lives inside the app via gomobile. There is no subprocess to manage, no IPC between a background service and the UI, and no service-restart handling.

Auto-accept folders from trusted peers. When you add a peer, you can toggle auto-accept so any folder they share is added to your device automatically without a prompt. Other pending offers show up as accept/ignore cards in the Folders tab.

QR pairing works both ways. Display your device's QR for a peer to scan, or scan theirs. The 56-character device ID never needs to be typed by hand.

UI updates in near real time. Long-polling /rest/events means config changes, folder state, and incoming offers reach the UI in about a second, instead of on a polling interval.
