+## Application Attributes
+
+Describes attributes related to client-side applications (e.g. web apps or mobile apps).
+
+| Attribute | Type | Description | Examples | Stability |
+|---|---|---|---|---|
+| <a id="app-installation-id" href="#app-installation-id">`app.installation.id`</a> | string | A unique identifier representing the installation of an application on a specific device [1] | `2ab2916d-a51f-4ac8-80ee-45ac31a28092` | ![Development](https://img.shields.io/badge/-development-blue) |
+
+**[1] `app.installation.id`:** Its value SHOULD persist across launches of the same application installation, including through application upgrades.
+It SHOULD change if the application is uninstalled or if all applications of the vendor are uninstalled.
+Additionally, users might be able to reset this value (e.g. by clearing application data).
+If an app is installed multiple times on the same device (e.g. in different accounts on Android), each `app.installation.id` SHOULD have a different value.
+If multiple OpenTelemetry SDKs are used within the same application, they SHOULD use the same value for `app.installation.id`.
+Hardware IDs (e.g. serial number, IMEI, MAC address) MUST NOT be used as the `app.installation.id`.
+
+For iOS, this value SHOULD be equal to the [vendor identifier](https://developer.apple.com/documentation/uikit/uidevice/identifierforvendor).
+
+For Android, examples of `app.installation.id` implementations include:
+
+- [Firebase Installation ID](https://firebase.google.com/docs/projects/manage-installations).
+- A globally unique UUID which is persisted across sessions in your application.
+- [App set ID](https://developer.android.com/identity/app-set-id).
+- [`Settings.getString(Settings.Secure.ANDROID_ID)`](https://developer.android.com/reference/android/provider/Settings.Secure#ANDROID_ID).
