About this app

🚀 Major Upgrade to Syncthing Version 2

⚠️ Important:
After installing this update, do not close or force-stop the app on first launch!
It will perform a one-time database migration that may take some time depending on the size of your setup.
Interrupting this process can damage your configuration or data.

Before upgrading: Please create a full backup of your data and export the app's configuration.

This update represents a major version change from v1.30.0.3 to v2.0.9 of Syncthing-Fork.
The internal database structure and configuration handling have been significantly updated.

To read more about the v2 milestone, please visit:
https://github.com/syncthing/syncthing/releases/tag/v2.0.9

If you prefer to remain on v1 (not recommended), please switch to the builds available on GitHub at:
https://github.com/Catfriend1/syncthing-android/releases

Disclaimer:
This upgrade is provided as is without any warranty. The developer cannot be held responsible for any data loss or configuration issues resulting from this update.



This is a fork of the Syncthing-Android wrapper for Syncthing that brings major enhancements like:
* Folder, device and overall sync progress can easily be read off the UI.
* "Syncthing Camera" - an optional feature (with optional permission to use the camera) where you can take pictures with your friend, partner, ... on two phones into one shared and private Syncthing folder. No cloud involved. - FEATURE CURRENTLY IN BETA STAGE -
* "Sync every hour" to save even more battery
* Individual sync conditions can be applied per device and per folder
* Recent changes UI, click to open files.
* Changes to folder and device config can be made regardless if Syncthing is running or not
* UI explains why syncthing is running or not.
* "Battery eater" problem is fixed.
* Discover other Syncthing devices on the same network and easily add them.
* Supports two-way synchronization on external SD card since Android 11.

Syncthing-Fork for Android is a wrapper for Syncthing that provides an Android UI instead of Syncthing's built-in Web UI. Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

Goals of the fork:
* Develop and try out enhancements together with the community.
* Release the wrapper more frequently to identify and fix bugs caused by changes in the syncthing submodule
* Make enhancements configurable in the UI, users should be able to turn them on and off

Comparison between upstream and fork at the time of writing this:
* Both contain the syncthing binary built from the official source at GitHub
* Syncing functionality and reliability depends on the syncthing binary submodule version.
* Fork gets along with upstream and sometimes they pick up my improvements.
* Strategy and release frequency is different
* Only the wrapper containing the Android UI is addressed by the fork.

syncthing is the best solution for synchronizing data across multiple devices. It's decentralized, which means there is no need for servers, for example a cloud service. This fork/app works as promised. In my case it even replaced any need for other backups, because I now store all my data on all devices I wish to connect. Even better: it's truly free! 🤩

Thanks :) However, please don't replace regular Backups with Syncthing. If files are (accidentally) deleted on one device the deletion will be synced to all others. Also depending where those devices are located they could be lost/stolen together or if really unlucky just fail at once. Always keep proper, real(!) backups of anything important.

Newly started using this app for syncing my Obsidian vaults on phone and computer. I like this app so far. Intuitive despite a learning curve, efficient and quiet useful. I like the fact that it doesn't send my data via cloud, but directly between the devices. It has provided an excellent alternative to obsidian sync for anyone who loves obsidian but can't afford to pay for the sync. I hope the app continues to work well. Thank you to the dedicated team behind this thoughtful app.

Really good file sync app. This was the second sync app I tried. The other app was highly recommended but I could never get it to work. I had this app installed and configured on my phone and chromebook in just a few minutes. I then copied some audiobooks into the sync folder on my chromebook and I immediately saw them syncing on my phone. I really like that I can see the progress in the notification. I synced 3gb in under 5 minutes over wifi and it was really easy. Highly recommended app.
