are there any android app for nostr which lets you select your relays (or defaults to an empty set of relays) before creating an account? i'm interested in using nostr for a private network with friends and only want it to ever connect to my own relay.

which one is working best for you?
this use of "fork" is a bit of a misnomer propagated by github. historically, a fork was a long term fracturing of a development community (often in response to poor stewardship of a project or hostile corporate takeover) rather than a short term diff or working branch intended to be upstreamed. language changes, but i think it's worth remembering the roots of this word.
