Whatsapp is the best app for any smart phone. It is used by Internet to send text messages, documents, images, videos, user location and audio messages in a limited length.
You can be connected with your friends, relatives and love once. You can also share your feelings, emotions and thoughts by this app.
It is useful and dangerous app both. In my view WhatsApp is like a weapons.
It is in your hand. If you use it as a social media, then it is good and if you use it for time passing then it is dangerous.
Youth and students are misusing this app. They are wasting there golden time of their life in chating with there girl friends/boy friends. Many people share communal and useless messages, documents, images, videos and audio for their fun.
It is very beneficial app because it is in your smart phone and you can use it any where anytime.
