Amethyst needs no shilling, but as requested: Amethyst has been my #1 used client since it launched. If you're an Android user and love features, privacy, and experiencing a wide variety of the Nostr ecosystem, Amethyst is for you. Amethyst also has some stability and performance issues from time to time, but I've always viewed this as a trade off to experience Amethyst's wide range of features that sometimes you cannot find anywhere else. Will might say that he's "spending all day looking at NIPs", well Vitor is the Master of NIPs.
