WhatsApp is a very popular cross platform mobile messaging App. The beauty of WhatsApp is that it saves users plenty of money due to low usage of internet and at the same time giving them realtime chat options with their near and dear ones. Another fact that helps WhatsApp is that it is free to use for the first year and thereafter it costs just a $0.99 or Rs.60.00 odd for full year. In fact it is so very popular that most people using PC and mobile would love to have WhatsApp on both their mobiles and PCs. Those who dont have smart phones or have old phones not supporting WhatsApp also would like WhatsApp on their phones.
