Would the use of the firechat be a secure means of communication?
https://en.wikipedia.org/wiki/FireChat
can be peer to peer
private encrypted communication and public chat rooms
seems like this could be an option if both sides use it, but there are smarter people on here in judging this option.
If you could promote an app for secure communication what app do you recommend? could that app also be used to find each other, (provider and client)?
