Keepass automatically syncs. Kypass (mobile) automatically syncs. All it takes is to enter sftp credentials to KeePass, and the rest is automatic. Not sure why you couldn't figure it out, but it works for the last 5+ years flawlessly. I didn't touch a single button to do anything extra, all I need is my SFTP credentials (once while setting up) and master password to open in my local machine.
