Yes. It's easy to install and runs on Android. It's quite fast in detecting differences and then syncing 2 nodes. It's meant to permanently run in the background though. It cannot be not easyly automated to, eg, sync 2 nodes and then shut down. In case if concurrent edits, you end up with multiple versions of the file on disk. You have to somehow detect those conflicts (find) and merge the files yourself. It doesn't help you much with that.
