Hmm don't know...
On android, i did/do a lot of things in the browser. When I used IOS some years ago, it was really "use the app or die".
Now on grapphene os -- its like 50/50. I use webpages or torbrowser where i can, but some things like simplex or podverse run in the app...
Its not always black or white, but why use an app if the app connects to net anyway and you can use a browser instead? Its like just updating the broeser, not 100 apps.
