There are millions of apps hosted on the Play Store, and all of them work great on your Android phone or tablet, but just a few advertise compatibility for Chromebooks, and fewer still for Android Auto (AA). It shouldn’t be confused with Android Automotive OS (AAOS), which is the open-source OS that powers infotainment experiences in cars right off the factory floor. AAOS doesn’t need a connection to a smartphone like AA since it runs the Play Store natively. However, AA is more widely available, easier for carmakers to throw into their products, and still offers a sizable selection of apps that benefit the user experience.
