# SyncUp (open-source file manager)

> SyncUp is a free, open-source file manager for Android and iOS. An open-source Syncthing client for iPhone and Android. It has 228 GitHub stars and is released under the MPL-2.0 license, and you can install it from F-Droid and the App Store.

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.
