WhatsApp – Blue Tick Marks?

WhatsApp has rolled out out a read receipt feature that will let users know when their messages have been read. With the new WhatsApp feature users will notice two blue tick marks next to a message they’ve sent, which is actually an indication that the recipient has seen the message.

Earlier versions of the app showed a grey double tick mark which indicated the message has been delivered.
