Announcement by the creator: https://forum.syncthing.net/t/discontinuing-syncthing-android/23002
Unfortunately I don’t have good news on the state of the android app: I am retiring it. The last release on Github and F-Droid will happen with the December 2024 Syncthing version.
Reason is a combination of Google making Play publishing something between hard and impossible and no active maintenance. The app saw no significant development for a long time and without Play releases I do no longer see enough benefit and/or have enough motivation to keep up the ongoing maintenance an app requires even without doing much, if any, changes.
Thanks a lot to everyone who ever contributed to this app!
It’s all in the open, you can go dig around for reasons. As usual there wasn’t a single simple one. Neither was it some kind of complete fallout, we e.g. collaborated on translations and I have been in contact around various things with the one that forked.
