The cross platform messaging app which is available for free to iOS, Android, Windows Phone, Symbian and BlackBerry users hit the milestone by adding 50 million new users in the apst two months. What's more staggering is that WhatsApp processes more than 31 billion messages a day.
WhatsApp is also adding a voice messaging feature in its latest update within the next 24 hours which will allow users in all platforms to send short voice messages, much like voice messages on phones. Members simply tap and hold the microphone icon to record a message that sends on release of the button, or they can slide their finger to the left to cancel the recording. WhatsApp is becoming a force in cross platform messaging and already has a head start on many of its competitors.
