I just started using https://mostard.org and finally it seems we have a decent nostr client that supports #monero tipping. I installed it on my grapheneOS device as PWA and for now it works flawlessly. The tipping process is imho way better than Garnet: instead of having an integrated wallet that was heavy on your device battery you can simply connect an external wallet of reference, like cake wallet or stack wallet and use it to receive/send tips. 
Just give it a try, monero community!

 what browser are you using to connect? 

 Vanadium, it works pretty fine 

 so pasting in your nsec? 

 Nope, it supports Amber 😉  

 Wow another possibility to tip with #Monero on nostr.
