The current version in Fdroid is 2.0.11.2 which is also from the nowhere-to-be-found developer

https://f-droid.org/packages/com.github.catfriend1.syncthingfork/

TIL one of the Lemmy devs is also a Syncthing dev, the official app - https://github.com/nel0x/syncthing-android-gplay#acknowledgments

Thanks, i thought the official app is no longer in development?

EDIT: i did not check before commenting but the link doesn’t include Android version
