WhatsApp may not be one of the first apps you think about when you think about sending a text but it should. WhatsApp Messenger is a smartphone messenger available for iPhone, Android and other smartphones. WhatsApp uses your 3G or WiFi (when available) to message with friends and family.
Switch from SMS to WhatsApp to send and receive messages, pictures, audio notes, and video messages. This little app that could has done very well. It sends more messages than Apple’s own iMessage. WhatsApp announced via Twitter that had processed a record 27 billion messages in one day. That’s 10 billion messages sent and 17 billion messages received. WhatsApp has about 200 million users. That astounding number makes it bigger than Twitter.
