It's been #Amethyst for a while, and I haven't seen any other Android clients that are anywhere close.

That said, I also use Spring Browser in order to more easily use web clients on mobile. Spring has a built in signer extension and you can set it up with NWC so you can easily zap on any web-app without having to set up separate NWC connections for each. Sadly, I think the project may be abandoned, as it hasn't had any updates since December 2023.
