Whats app is an amazing messaging app and is very useful for chatting. This app is also used to send photos and videos to the selected people in friends list. Apart from chatting with individuals it also provides group chatting where number of peopke are joined to form a group. It also enables users to call other persons who are having whats app. Video calling is also possible through this app. I like this app so much because we can send photos which are snapped through our mobile camera using this app
