Everyone knows all the apps on your phone

I still, will never understand the need for native "Apps". To this day, I have never seen an "App" that couldn't simply have been a website/webapp. Most of them would likely be improved by being a webapp.

The only benefits I can see of "Apps", are the developer get's access to private information they really don't need.

Yeah, they get to be on the "App Store". But the "App Store" is a totally unnecessary concept introduced by Apple/Google so they could scrape a huge percentage in sales.

Web browsers have good (not perfect) sandboxing, costs no fees to "submit" and are accessible to everyone on every phone.
