i use a wide variety of nostr apps on the daily an weekly, so this is pretty hard to answer. i'm going to say my favorite nostr app right now is Notedeck from the Damus team. it's my number one used desktop app. i use it daily, having it open all day long.

why is it my favorite? because of it's potential for not only power users, but for developers and for every day users too. Notedeck is a nostr browser, but looks and feels like a 'Tweetdeck' app having multiple configurable columns and decks.

it's still early and needs more features to be well rounded for everyone, but im bullish on it's potential to keep me organized and help me never miss a note or piece of content from nostr.

im really excited to see what developers and non-developers build for Notedeck.
