There’s a good chance that you started hearing about WhatsApp sometime in 2013. It started the year with somewhere around 150 million users and was over 400 million users by the end of the year. But if you’re still not sure why WhatsApp is the Next Big Thing, here’s a quick explanation.
WhatsApp is a private messaging network. It gives you the functionality of a standard text messaging system without having to worry about messaging fees. Once you’re using it, it works a lot like any other chat program: Facebook Messenger, Google Talk, Skype Chat, and so on. However you don’t need to use a username on WhatsApp. When you set up WhatsApp Download for the first time, it adds your phone number to the global database of users. You never need to remember a username or PIN and you don’t have to add another line to your contact information—anyone who knows your phone number can find you on WhatsApp. Even more, when you install WhatsApp it goes through your contacts and matches them to the same user database. So as soon as you set it up, you can find out which of your friends are already using WhatsApp and start chatting with them for free. If one of your contact signs up for WhatsApp, they will automatically be added to your list of WhatsApp contacts.
Well, its almost free. You still pay data charges along with a small yearly subscription fee ($ 0.99, €0.79, ₹60) after the first year. On the other hand, there are no ads, and WhatsApp is a great deal for many users, especially those who send international texts. The low cost and ease of use have combined to make WhatsApp a worldwide success.
WhatsApp offers roughly the same features as other chat programs. You can create a temporary group chat with up to 30 people. This provides a convenient space for friendly conversation or an inexpensive international meeting. WhatsApp also offers an exceptionally large selection of emoticons to use when you can’t think of the right word in the right language, and supports video and photo messages. All this comes through a clean and simple interface that is especially easy to understand and use.
Of course, as with all good things, there is a tradeoff. We mentioned that anyone who knows your phone number can find you on WhatsApp. That includes people you don’t want to find you. You can block users, but by default you can be contacted by anyone from any place in the world. Furthermore, the WhatsApp user database records the numbers of all your contacts so that it can quickly add new numbers. A database of over a billion cell numbers is a tempting target for hackers, and WhatsApp has faced a number of questions over security and privacy. However, if you’re OK with the potential risk to privacy, WhatsApp is by far the easiest, most efficient, and cheapest way to chat with contacts around the world. it is available for all major platforms like windows , android , ios etc …
