As an Android Maxi, I don't know how TestFlight works. I would assume it's tied to your Apple account, but I would also assume you could use as many devices as possible with that account. I could be entirely wrong here.

Tied to your App Store account. One slot gets the app for all your phones and iPads AFAIK.
good to know. thank you.
What client do you use on Android?
i use Kiwi browser + nos2x extension + astral.ninja and snort.local.
I'm hoping that Nostros by #[3] can become my daily driver soon. It's getting better every few days!
