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.
While apps are spying etc, making them is usually a no-brainer compared to churning and leaky web stacks. And probably not a single time a webapp loaded for me when I tried it outside standing in the wind trying to figure something out. It was always an app that started and helped and didn't ever scroll horizontally while doing so.
