WhatsApp is an iPhone and Android messaging app that lets you send messages without having to pay for SMS. Besides the basic messaging, WhatsApp users can create groups, send each other unlimited images, video and audio media messages. You can even take WhatsApp on the web. WhatsApp Web is basically an extension of your phone: the web browser mirrors conversations and messages from your mobile device -- this means that all your messages still stay on your phone. To connect your web browser to your WhatsApp client, simply open https://web.whatsapp.com on your browser. You will notice a QR code --- inside WhatsApp, scan it, and you're ready to roll. Now, you have connected the WhatsApp on your phone with the WhatsApp web client. It is necessary that your phone stays connected to the internet for our web client; in addition, please install the latest version of WhatsApp on your phone.
