If your app works with Alby, it will work with Nostore too. But it could be that you haven’t tested the UI on mobile Safari. I started testing your app but i just don’t have enough BTC in my lightning wallet to get going with the test. 

I think the market for people wanting to spin up a nostr server is just small right now because people don’t know exactly the benefits of doing such or *how* it should be used once they have it. Write to one and read from many? Write to many including your own?

If someone wants a nostr relay, I don’t think the friction of your signup is going to deter them
