WhatsApp, one of the worlds most popular messaging app, has introduced a new feature in its latest update. The messaging app, which allows users to send free messages anywhere in the world, as long as both parties have an internet connection, will now tell them whether the recipient has read the message. The famous tick now has a blue hue.

A single tick means the message has been sent, double tick means it's reached the recipient and a blue double tick means it has been read.

Indian users woke up early this morning to an update on their mobile phones and Twitter was flooded with comments.
