I'd like to know too. Since Plebstr closed down I have been using Primal, but I despise the wallet connection options. I have tried Amethyst before but the UI is so bad, I can't force myself to use it. I have been on the lookout for a decent android client.
The only other viable one is Freerse, but it's not open-source and still pretty buggy. Nostrudel is pretty good on mobile, but doesn't have that classic mobile *look and feel*.
I have given Nostrudel a try and it looks great. Thx
Please provide constructive feedback to nostr:nprofile1qqsyvrp9u6p0mfur9dfdru3d853tx9mdjuhkphxuxgfwmryja7zsvhqpzamhxue69uhhv6t5daezumn0wd68yvfwvdhk6tcpz9mhxue69uhkummnw3ezuamfdejj7qgwwaehxw309ahx7uewd3hkctcscpyug. I've been trying to help make it better. I think Amethyst needs more UI work than new features.
I have tried to help. I do specialize a bit on the UI/UX aspect of things. I do not believe any of my advice made it to production. I even drew a couple mockips iirc.
