@andreas No no no, don't get me wrong, I NEVER approved of Bat Messenger. They seem very sketchy indeed and I find their app running crazy smooth for the claims they make.

It seems to be tested. I wish the owner of the website would keep more updated on testings as well as do a test on Session, but don't know where to contact them.
