I had a quick look at it yesterday and it's pretty neat.

I have a question, and maybe I missed something very obvious. Is there a way to add an nsec to the app so that when you open the different nostr clients it connects with that nsec automatically? 

 In Android, PC, and Mac, it automatically connects with your existing browser extensions. On iOS, it's currently not possible due to WebKit limitations. I once considered building an inbuilt key manager, which would be the right direction. 

 Oh, that's why. I have no browser extensions on neither Android nor PC 😅

It'd be nice to have some kind of key manager built in 💜 

 Extensions are a great & safe way to use nostr on web, highly recommended.  

 I was on a PC, had to install Brave to have a Chrome based explorer, so it was fresh out of the box. No extensions, no nothing 😅
