Is there any good mobile client based on smack?

i am looking for a pretty open xmpp client for mobiles.

actually as decent ones i know :

  • conversations
  • xabber
  • chatsecure
  • monal

none of them support voice calls or video calls

jisti android was supposed to do that but project is on hold jitsi community seems only focused on jitsi meet project

do you know any initiative of a good mobile xmpp client (paid o opensource app) that would include calls ?
