Google Maps sends push notifications to nudge users to complete a desired action

In this example, Google Maps sent a push notifications to nudge users to complete their timeline, thereby making an accurate picture of where the user has been in the past.

Why we think this push notification is good:

For Google Maps Timeline feature to be an accurate portrayal of where the user has been to the past, they need input from the user to verify that what Google had detected was actually where they were. This is an excellent example of getting confirmation from the user to ensure consistent and accurate data, and can be applied to other apps that need user input for it to be valuable.
