It may seem that way but only in the sense that people have a choice. For me there is no point to compete with Damus, my goal is to get more people to use nostr. This is also the reason why in the early days I posted a lot less than I could on nostr to try to get people to use my app, why would I? The only other iOS nostr users were Damus, and they were already using nostr.

So no, Nostur doesn’t compete with Damus, it competes with centralized social media.

Not sure what you meant with the rest but you can use all my code (GPL license) and I’d gladly help anyone sharing the same goal.
