Yeah, I use it every day and have synced over 80k photos and videos to my servers with it. I absolutely love it. I know of no other option and I do not trust Immich or Nextcloud sync. I have never ever had an issue with photosync and if there is ever a rare error it tells me why.
I have it set to rsync to my local server. I open the app. It has already selected the recent media that is unsynced to said location. I then press sync and it does it in the background.
I believe the paid level above pro has some sort of auto sync based on location but I chose to not get that because I didn't need it.
Super, super recommend!
