coolest thing about building on #nostrdb is that it comes with command-line tools and a portable database that is just a single file.
you can copy your nostrdb node from damus-ios to notedeck and back and it will just work (todo: actually implement ios export). it has all of your nostr data, contacts, profiles, bookmarks, notes, mutelists, decks, everything! It also includes a fulltext search and relay index.
sure you can use relays for this, but its nice to have a local copy you can backup and redistribute later.
eventually your nostrdb nodes will just automatically sync so you don't have to do this manually.
