ELI5:Why do companies push to install their mobile app when you visit their website? What sort of information they get from their app vs a web visit?

In a lot of cases, it's not as much about collecting information on you as it is getting you to use their electronic presence more. 

Having a mobile app is really convenient, and you're more likely to have it within reach and to use it than the alternative of opening up a web phone browser and trying to hit their internet site. 

Since you're more likely to use that convenient, in-reach app, that means you're more likely to have more interactions with the business that is providing that app. 

That translates directly to more brand recognition and more sales, and even more visits to their physical store (if they have one) instead of the competition's. All of these - heck, even just any ONE of these - are great for businesses.
