Damus was one of the first iOS clients afaik. Originally had zaps but Apple didn’t play ball but there is a work around. Zapping a profile and not a post. I think primal found a way to integrate zaps better 

 gotcha, thx you.  I'm on Android. 

 Ah ok, amethyst seems to be the go to for Android but i think @jb55 is working on Damus for Android 

 Sweet.  I will give Amethyst a try.  Thank you! 

 🙌 yes!
