About this app

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.

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.

Great free and open source solution! Takes some knowledge to set up, but in the end, it does everything I need! I'd love to see a notification feature, such that if a connection hasn't been made in xx hr/days, I will be notified to fix the issue. Lost some data recently when my SD card corrupted and I didn't realize syncthing service hadn't been running on my server.

Developer just decided to change the meaning of "~" in paths, breaking most of my sync configs on my tablet. Going to have to delete and recreate all share settings, instead of just editing a single text field for path that the developer gets to change, but I don't. Thanks for protecting me from...? Who is protecting me from the developer's whims? Don't want to update app on my phone, yet.

Sorry for the inconvienence, but it was necessary to implement this change at some point. Not being able to edit the path afterwards however is a conscious design decision and not "whim". It’s not obvious what it should mean for the local files if you edit the folder path, and any choice that we could make will be wrong or dangerous in some cases.
