The app brings Android Auto to anyone with an Android running 5.0+ with a data plan. Even if you don't have a compatible car, people can now enjoy the benefits of Android Auto. The app is a huge improvement over the built in apps as it incorporates safety and short glances into the UI. The buttons are larger and the interface utilizes a high contrast, voice driven experience.
