I’ve been using Syncthing-Fork for a while now. It seems to work fine for me, however you do need to launch it occasionally as sometimes it can get killed when backgrounded depending on your flavour of Android.

It’s been a weird situation.

• Discontinuing syncthing-android - 2024

• But then they list Syncthing-Fork in the docs, seemingly giving the fork their blessing

• https://github.com/catfriend1/syncthing-android <-- the fork repo

  • doesn’t publish to Google Play
  • some other person named nel0x publishes the Google Play releases
  • Catfriend1 only publishes on F-Droid and GitHub

So I guess your main options are:

• F-Droid
• Google Play
