With Arrival Control, you can temporarily share your location with friends and family to let them know that you’re on your way and how long it will take for you to get there. So, if you’re running late, the people you have selected will see your new estimated time of arrival on the app, in real time. And when you arrive at your destination, the location sharing automatically turns itself off for maximum privacy.
Not only for iOS and Android, It is also available as a web app for PC or any other smartphone with a modern browser.
Although it’s a Deutsche Telekom product, Arrival Control is also available outside of Germany in English and German. If you want more information, including how to use it for your business, you can jump to Deutsche Telekom’s site (in German).
