Git + Ledger (or other plaintext accounting tools) actually works pretty well. I did that for several years, though the habit/routine broke for me last year. It let me keep the files in sync between my phone and my computer(s).

I'm not sure it's worth a writeup as anything special, git is (for programmers especially) a conventional way of keeping things synchronized between devices. I also used Dropbox for a time, but I specifically wanted versioning to help keep track of edits and reorgs of my files so I switched to git.
