Replyve is more of a calling app that provides “Call to Chat” to communicate only via real time chat messages and does not require voice to talk over call.

Its a new form of internet call to communicate in real time that requires all of your attention.
Unlike Voice/Video call, the messages in Chat Call are conveyed by exchanging information only via modern feature-rich chat messages.
