Some neat nostr apps (see nostrapps.com for more):

Dtan.xyz - torrents over nostr

Nostrudel.ninja - nostr power client

zap.stream - streaming, paid with lightning, nostr chat enabled

Listr.lol - make, discover, manage lists

Habla.news - write long form content

npub.pro - easily create websites out of your nostr notes

heya.fund - start lightning fundraisers (native to nostr) - needs better integration IMO, super powerful!

Emojito.meme - create and add custom emoji sets

https://obsidian.md/plugins?search=nostr#. - plugin to write to nostr from Obsidian

plebeian.market - sell stuff for sats, nostr enabled

flare.pub - youtube on nostr
