Any app UI you wish to see? Let me know!
So far on my list:
threads
Telegram
TikTok
Signal
Discord
Lyft
Zillow
Airbnb
Substack
Robinhood
Starbucks
Kick
Discussion
Wise
IKEA
Cashapp

I don't know any of those, except the open source apps. (Telegram and Signal)
Google Classroom LMS (Nostr Classroom) would be a killer app!
