Instagram is app, where you get to know people around you and you can post your own pictures on it and share with the whole world.This app is pretty cool because you find each and every person so attractive because of their pictures on there profile and u get to know about them very well and its really supportive from the security point of view and it provide privacy option as well which is so good.Design is attractive but sign which was visible before that wooden camera was more cooler. Instagram is so easy to operate and easy to explore.I think people all around the world are using this app.
