no, haven't tried that one. and it was a bear getting my family/friends on Session. but i've used Signal, then switched to Threema, and now Session.

but i would recommend anyone to use any other third-party communication app that supports E2EE rather than iPhone/Google's app. 

 Keybase is my messaging, git, vault, and file services to go.  I'll drop Keybase when nostr catches up.
