Seems like it will be around for some time, based on the developers comments

Hi, Syncthing-Fork is a personal project, originally meant to keep the Android app alive for my friends and family. I’ve shared this work from the very beginning and will do so when I hit the code for updates. I will primarily do compatibility with the Android phones “we” use here, so that’s currently the range from Android 10 to 14. Feature development is currently not on my roadmap. I myself use the app and depend on the availability of Syncthing on the Android platform for my own workflows. You’re welcome to use the releases on F-Droid or my GitHub if you like the fork. Kind regards, Catfriend1

Is there really? Long time splunk admin, I would love to see this
