Apple Watch apps aren't all about sorting payments and getting notifications. There are plenty that play nice with your car, too. Following the likes of BMW and Volkswagen, Mercedes-Benz announced its own software for the wearable that provides walking directions to and from where the car is parked. Using the MB Companion app, Mercedes owners can also search for driving directions from the Apple Watch or and iPhone before they even sit down in the driver's seat. As you might expect, info like fuel level, range, maintenance codes and and odometer readings can be swiped through on your wrist, too. When it arrives this fall, the app will work with Mercedes-Benz C-Class and S-Class vehicles that sport the Command Online tech, and support for other models is said to follow after launch.
