My Favorite Smartphone App.

Today, I introduce my favorite App.

My favorite app is Instagram. It is photo sharing app. 

And it is popular among young people.

There are some reasons why I like this app.

First, I can get the latest information. For example, When you make travel plan, it help you  decide where to travel. 

Also, We can connect with old friends and overseas friends through uploaded photos. we can communicate with them even if you don't meet directly.
