Enabling App Presence will allow you to target your campaign only to users who already have specific apps installed on their device.
This can be used to reach a more specific target audience and increase your bottom line. For example, if you are promoting a casino app, you can choose to target your campaign only to users who have the top-grossing casino apps already installed.
To enable this feature, go to the Audience tab found in the Campaign Targeting section. Click "Enable" and insert the apps of your choice by their package name.
App package names
In order to use the app presence option, you need to insert a list of Google Play package names in the text box (insert one package name per row). Your campaign will be served only to users who have one or more of the apps listed in the package on their device.
You can find the app package name by looking at the URL link of the Google Play page of the app you would like to add.
The package name is what comes after the "=" sign.
That is, the package name of the Start.io (Formerly StartApp) Showcase app shown above is: "com.startapp.showcase"
Insert only one package name per row. In order to prevent a severe drop in potential traffic, we recommend using this feature with at least 5 applications.
