You can, but _you_ need to figure out how to do it. If don't know how or can't be bothered, you can pay for Obsidian Sync - which Just Works. I tried to roll my own syncing with syncthing and iCloud and Dropbox. In the end I spent so much time debugging and dealing with files clobbering each other mid-sync I figured out $4/month to support a project I use daily isn't too much. Zero problems since and I use Obsidian regularly on 4 different devices.
