SoriChat

SoriChat is a cloud based communication service that is designed to simplify remote collaboration between teams across and within organizations. Users can create private rooms and invite people for asynchronous conversations using instant messaging, voice and screen recordings, file sharing and real time voice calls.
You can sign in with email, Google and Apple accounts. You can block users or simply leave the rooms. Deleting your account will remove all your personal data as well as your Apple login.
