After years of using Feeder on my phone and some other random stuff on my laptop, I switched to FreshRSS on my server and the big thing is everything stays synced. My read and stared articles are all where they should be. I run fluent reader on all my devices and tailscale keeps me always connected to my reader so I can save articles on my phone when I don’t have time to read them then read them when I get home on my laptop or tablet.

If you go the android route turn on Apps Only Mode in the settings. It gets rid of the home screen ads for the most part and disabled a lot of the “features” that Google tries to push.
