Well, it's aimed at people like me, who spend 12 hours a day on our laptops and PCs and just want to turn the crap off and go for a walk and talk to actual people without distraction.
There's a reason why I almost only use a Nostr app in a browser: I use Nostr on my laptop. That keeps me from doom-scrolling and allows me to see a lot of Nostr posts, quickly, and then stop.
I would just want to side-load #Cordl Android and use that and Signal/SimpleX/Threema on my phone, to make sure people can contact me at meetups.
