Alternatives for some of the apps I was using such as Google Calendar, Google Keep, etc and so on... https://simplemobiletools.com/
@rakor Don't see much difference between that or NextCloud or OwnCloud. But definitely another good option.
@pkimpton well owncloud-sync was always a bit freaky here and drained my battery. Plus, you don't need a server running, because it is decentralized.
@rakor Either way if I need to transfer notes or text files or music and videos between my laptop and phone I have an ssh connection open all the time on the roommate's router.
@pkimpton of want to sync it try out syncthing. I use it to keep my stuff synced and it is fine and open source
