It applies to Mobile Push Notifications and In-App Messages in Mapp Engage. All targeting logic and time thresholds are defined by the marketer. --- ## Example setup A marketer wants to inform app users about a new release and encourage them to update. Instead of notifying all users, the setup targets contacts whose **app installation date indicates an outdated version**. This ensures that update reminders are sent only to contacts who are likely to benefit from them. The following screenshot shows the finished segment with the **App Installation Date** criterion applied. ![](https://cdn.document360.io/554b9b98-6720-4d8b-9919-c7b203d72648/Images/Documentation/0a64f916-45d9-409d-a5d2-90fccb3022f1.png) The segment is then used as the target audience for mobile messaging. --- ## Steps 1. Create a segment using the **Mobile Activity** criterion. 2. Select **App Installation Date**. ![](https://cdn.document360.io/554b9b98-6720-4d8b-9919-c7b203d72648/Images/Documentation/CleanShot 2026-01-09 at 09.22.16@2x.png) 3. Define a relative condition (for example, *installation date is more than three months ago*). 4. Use the segment as the **Specific Target Audience** in a Mobile Push Notification or In-App Message. 5. Link to the App Store or Play Store so contacts can update the app. --- ## Notes - The segment is based on installation status and installation recency, not app usage behavior. - Mobile Push Notifications and In-App Messages differ in delivery context: - Push notifications are sent regardless of whether the app is currently in use. - In-app messages are displayed while the contact is actively using the app.
