Amethyst is very good IMHO. It has ZapStream streams built in and it allows your lists you have made for feeds. Good lil app. Have you tried that Spring app? That's awesome as well.

I've watched streams via Amethyst, it's my primary app atm though I can't stream from it so far as I know - I tried Spring, it's brilliant, very well made UI and I think I'll end up using it more and more over time
Prism on mobile is good for streaming and let's you do a custom RTMP no charge. I think SLOBS has a mobile app too like nostr:npub1de6l09erjl9r990q7n9ql0rwh8x8n059ht7a267n0q3qe28wua8q20q0sd mentioned
