I dont use nostr on mobile. On desktop I have to use 4 clients to do the most basic things, and can barely write a note without an error say 50% of the time. Sadly, oddbean seems down. I can like and I can zap, most of the time. I dont dare follow or change relays. Occassionally I try and do surgery on my profile with the command line. And I've been using nostr for over 3 years. We are still early.

Why you don’t use on mobile? Cause it eats too much data ?
I use subkeys on mobile. I dont want to expose my main key on mobile. But since most clients dont support sub keys, it is of limited use.
