It's no being worked on at all. It was released, an update or Twp were made with small community requests, and then nothing. It was monerujo integrated with amethyst.

What would be good would he an XMR wallet with an API that allows it to get unsigned transactions, sign them and then broadcast them, and a nostr client that can make the request, and allows for some user defined behavior like displaying custom kind 0 tags.
