Seriously. I don’t want to install something on my phone when the dev is just using a WebView, if that’s what it’s called. When the app is basically just a website with the browser hidden.
What’s the reason for that? To attach the customer? To sell the app for money? Is there more ad revenue that way? Do you reach more people?
(Are there any good reasons for it, too? Security, maybe?)
To spam you with ads and steal more of your data of course! Look at the insane permissions on these apps: There’s no reason for them to have access to your contact list, text messages, app manifest, etc. The vast majority of apps have wildly unnecessary permissions because it gets the companies more of your data.
