Article or blog on website that shows the features available via the manufacturers own app

Some questions on another thread made me think that there ought to be a chart/table showing the various car brands, the app name, the features it has available for the cars with screenshots so an assessment can be made of how good/mediocre they are before switching cars or getting your first Onto car.
The table should also include the ‘features’ duplicated in the Onto app too.
