Android Auto is the version of Android tailored to car information systems and thanks to which applications specially designed for vehicles can be installed, from those that are specifically for cars to those adaptations that work through being linked to a mobile phone, such as Spotify.
Android Auto Store: install Android Auto apps on your mobile
The thing is that these Android Auto apps cannot be installed onto a mobile device, because there is always someone who wants to, unless it is done from a computer. Fortunately, the developer of AAStore has been good enough to develop their own Android Auto app store for mobiles and tablets, meaning that anyone can install them directly without going through a convoluted process.
This application features a very sober design and works exactly the same as any app store: you take a look at the app catalog and download and install whichever you like. However, for the moment, the offer is rather limited, but you are able to get apps featuring a minimalist design and that are focused on usability in a car, while also being able to be used on your mobile device.
