When you first open App Tracker™ you are taken to the Tracking portion of the application. You can add an app by it's ID in the tracking section or tap the APPS icon at the base of the screen to search for an app by name.

Depending on the version of App Tracker™ you are using you will be able to add 1 - 10 apps to track at one time.

Once you have added an app to track the icon and title will appear in the tracking area along with it's overall rank in the category, highest recorded rank in the category and the current type rank (free/paid) and highest recorded type rank.

Information on your app is refreshed daily so you can check back every day for the current rank.
