# Notify app users with outdated installations about a new release

## Overview

This example shows how to notify existing app users about a new app version based on their installation status.

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Instead of notifying all users, the setup targets contacts whose **app installation date indicates an outdated version**.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.

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.
