+  - AppExitReason
+---
+
+Introduced in SDK v4.0, the ``AppExitReason`` API allows developers to provide a
+reason when terminating their application. The system uses these reasons to
+determine where the user should be sent when the current application terminates.
+
+At present there are only 2 ``AppExitReason`` states when exiting an application,
+but this may change in future updates.
+
+### APP_EXIT_NOT_SPECIFIED
+
+This is the default state and when the current watchapp terminates. The user is
+returned to their previous location. If you do not specify an ``AppExitReason``,
+this state will be used automatically.
+
+```c
+static void prv_deinit() {
+    // Optional, default behavior
+    // App will exit to the previous location in the system
+    app_exit_reason_set(APP_EXIT_NOT_SPECIFIED);
+}
+```
+
+### APP_EXIT_ACTION_PERFORMED_SUCCESSFULLY
+
+This state is primarily provided for developers who are creating one click
+action applications. When the current watchapp terminates, the user is returned
+to the default watchface.
+
+```c
+static void prv_deinit() {
+    // App will exit to default watchface
+    app_exit_reason_set(APP_EXIT_ACTION_PERFORMED_SUCCESSFULLY);
+}
+```
