1. Can I extend the functionality of my web app using native code where necessary (adding background GPS geofences, etc) There doesn't appear a reason as to why not? This should be doable. 2. Do I have access to the real modern web stack in the compiled app? Yes. The webview Red Goose provides is basically the thinnest it could be. All your users get to see on the front end is your choice of web stack. 3. Does my iOS build support offline caching via my web app's service worker? Yes, it does! [1] Haha! And that's the main reason why I believe there is little value in coding up the whole business logic in native stack again. Although, I could be wrong here, and we are just starting to explore this vertical with the enormous power of PWAs.
