Hot tip for my Android peeps who want to play with all the fun nostr sites that require extension logins.
Download the Kiwi browser. It's a tweaked version of Chrome that allows extensions, unlike other mobile browsers.
Add the Nos2x extension, and set it up with your private key. It's a little odd, because instead of pop-ups you get a new tab, and you have to close it after authorizing something, but it works.
Alby will work on Kiwi as well, but it doesn't seem to work for Nostr login the way it does on desktop yet. So Nos2x is a must.
This let's you use all kinds of fun projects like logging into
Nostr.band (Tons of stuff, trending people, analytics, good search, etc. Logging in let's you follow with a click)
Listr.lol (Curate follow lists to use for managing your bookmarks and feed)
Kind3.xyz (backup your follow list and change your follow lists to other people's for fun)
Primal.net (super new web client that has lots of features)
Nostrit.com (schedule notes)
And way too many more. Almost all of the web clients support nostr login now.
