I tried it last week. The mobile client is solid but still a bit glitchy — about on par with Nostr mobile, in my experience. I’d expect a public release in June once they’ve ironed out the bugs. As for Nostr’s censorship-resistance claims — they’re pretty weak. When real Bitcoin-level censorship resistance was on the table, there wasn’t much interest. The focus seems to be on building a Twitter clone, which makes sense given that most of the ecosystem is funded by Twitter’s founder.
