WhatsApp is a popular app that I’m sure many of you have heard of, but what is it really for? It’s an application that effectively replaces a lot of the communication your phone is already capable of. WhatsApp allows you to send text messages, pictures, videos, and your location and contact info, easier, cheaper, and faster than services provided by our cellular phone providers, and with no limits on how much you can send. It does this all for free for the first year, and will continue to do this for only $.99 a year after that, and doesn’t bother you with pesky advertisements! With 450 million monthly active users, this was such a great business idea that Facebook bought the company for over $16 billion earlier this year. WhatsApp is especially popular in Europe, India, and Latin America, and it’s gaining ground in North America as well.
