What is WhatsApp and why is it so popular?
What is WhatsApp?
WhatsApp is an application available on iOS (iPad and iPhone), Android, Blackberry and Nokia that allows users to send text messages to each other. Initially that does not sound very special, does it? That's because a few key features have been left out.
WhatsApp lets you send texts for free. Yes, 100% free. You will never be charged for a text sent through WhatsApp. This is because WhatsApp sends messages through an internet data connection. This is one reason that WhatsApp iPad is available; usually the iPad is not able to send text messages. However, with this application it is.
WhatsApp is cross platform. Regardless of whether you have WhatsApp installed on your iPad, Blackberry, Nokia or Android phone, you will be able to send messages to anybody who also has WhatsApp installed. This is one feature that allows it to be a step up from Blackberry Messenger - although BBM is a great service it is only good for people who have Blackberry phones.
WhatsApp supports many different message types, from simple text to pictures to audio files. Usually a MMS message would cost a fair bit of money to send (I got charged $0.40 for a picture message once!) so the fact that these can be sent to as many friends as you like for free is great.
