I’m thinking about running FreshRSS on my local Linux PC, but my computer isn’t on all the time.
Basically all I want is to have read/unread status synced between my PC and other 2 phones. Could I have that? Most of time my PC would be off and I will be reading articles on phone, would the read status be synced to PC once it’s on?


Depends on the client actually. If your phone app’s client stores state and syncs whenever the server is available, then this setup works. If the client does not, and tries to sync live state, then it will only work if the freshrss server is also up and running.
On iOS, I know Fiery Feeds saves state and syncs when the server is available.
