Is a special view, designed to help you keep track of how many times your application was actually used by your users. It requires some tinkering before it's ready to use as you have to manually insert code into your application's source code. The SDK alongside with some samples can be found here.
As it doesn't require your application to actually be installed, you should note that there isn't a direct correlation between the data shown here and the data shown in any other view.
You can find a demo of this view by using the following link:Launch View
