Oddly enough PWA / Webapps was the original design intent for the iPhone (before the app store) and why it shipped with for the time the most advanced standards based browser on mobile.
I have yet to experience a PWA that is as quick to load or easy to navigate (smooth scrolling / responsiveness) as a native or hybrid native mobile app.
There always seem to be odd “browser” based glitches from errors from page loads or rubber banding or zoom / cliping of the UI at times.
