Last release was in July 2024. Last merge in August 2024. Not available (in the US) on the Play Store or F-Droid. Did not try downloading the apk from their website because no.

I'm curious how the sync is pulled off without a central server. Unless you port forward to your phone, device-to-device sync is always difficult without something in the middle.
