notedeck is completely powered by this, which is why its crazy fast. Still in the process of moving Damus iOS to it, but it is in damus iOS in a limited capacity (profile search, tagging, fulltext search, walking threads). Damus iOS just lacks using it for all queries atm. Another cool thing that notedeck will do is host many different nostr apps at once. Like a nostr OS/browser. This means all your nostr apps can interact with each other while you’re offline.
