I've switched to KeePassium. Not quite as polished UX, but works for me
SyncTrain has been working well, but all the knobs in the advanced folder settings definitely reminds me that I would never recommend it over Dropbox/iCloud/etc to almost anyone, heh.
But as long as I don't run into frequent problems, I like the idea of p2p device syncing over LAN. The phone in my pocket ends up passing around the latest copy since my other devices are almost never on at the same time. It's kinda cute.
Huh, this is interesting… If you have any specific UX pain points, feel free to reach out.
