Purpose of the App
The main purpose of Syncthing-Fork is to replace cloud-based file syncing with a private, decentralised system. Many users do not want their personal files stored on third-party servers due to privacy or cost concerns. This app allows files to sync directly between devices using encrypted connections. It is relevant for people who want private backups, shared folders between trusted devices, or secure file transfer without relying on Google Drive, Dropbox, or similar services.
Key Features
Syncthing-Fork adds several useful enhancements over the original Android wrapper. The app clearly shows folder-level, device-level, and overall sync progress directly in the UI, which helps users understand what is happening at any time. Individual sync conditions can be set for each folder and device, giving better control over battery and data usage.
A special feature called Syncthing Camera allows two phones to save photos into one shared private folder without using any cloud, though it is still in beta. The app includes an hourly sync option to save battery, a recent changes screen to quickly open updated files, and clear explanations about why syncing is running or stopped. It also fixes the common battery drain issue and supports two-way sync on external SD cards on newer Android versions.
How to Use the App
To start using Syncthing-Fork, install it on your Android device and also set up Syncthing on your computer or another phone. Open the app and complete the initial setup. Each device generates a unique device ID. Add another device by scanning or entering this ID. Once devices are connected, create or select a folder to sync and choose whether it should be one-way or two-way. Approve the folder on the other device. The app will begin syncing automatically based on your conditions, even resuming later if the connection drops.
Benefits of Using the App
Syncthing-Fork gives you full ownership of your data. There are no storage limits or subscriptions because files stay on your own devices. It is ideal for syncing photos, work files, study notes, or backups. Local Wi-Fi syncing is very fast and does not consume mobile data. The app also works well offline and syncs changes once devices reconnect. Overall, it offers privacy, flexibility, and long-term reliability without hidden costs.
App Performance & User Experience
The app performs smoothly on most Android devices, including mid-range and budget smartphones. Sync speed depends on network quality, but local transfers are usually quick. There are no ads or tracking, which makes the experience clean and distraction-free. The interface focuses more on function than design, but it clearly explains sync status and background activity. With proper battery optimisation settings, background syncing remains stable without excessive power drain.
Is the App Safe to Use?
Syncthing-Fork is considered very safe for file syncing. All data transfers use strong encryption, ensuring files cannot be read by outsiders. Since the project is open source, its code can be reviewed by anyone. The app does not upload data to any central server. Permissions are limited to storage, network access, and optional camera use for specific features. Users should still secure their devices and share device IDs only with trusted people.
Who Should Use This App?
This app is best suited for privacy-focused users, developers, students, and professionals who manage important or sensitive files. It is also useful for people who want local backups or file syncing between personal devices. Users who are comfortable with basic technical setup will benefit the most. Those looking for a very simple, cloud-like experience may find it slightly complex at first.
Pros and Cons
| Pros | Cons |
|---|---|
| No cloud dependency and no ads | Initial setup can be complex |
| Strong encryption and privacy | Interface is not very beginner-friendly |
| Advanced sync and battery controls | Requires multiple devices for full use |
Common Issues & Simple Solutions
Some users face issues with syncing stopping in the background due to battery optimisation. Disabling battery restrictions for the app usually fixes this. If devices do not discover each other, ensuring both are on the same network helps. External SD card syncing may require additional permission setup. Reading the built-in explanations or the project wiki often resolves most configuration-related problems quickly.
