The check marks that appear next to messages sent with WhatsApp indicate the state they are in and more precisely when they were sent by the sender and received and read by the recipient. You'll see a single gray check mark appear when the message has been sent from your device, two gray check marks when the message has been delivered to the recipient, and two blue check marks when the recipient has read it. In order to view this information relating to WhatsApp messages it is necessary to enable the function called "Read receipts" through the "Settings" menu.
