Google is pushing this further: https://www.xda-developers.com/deeply-integrated-progressive-web-apps-are-already-live-for-chrome-on-android/
On Chrome Dev (behind a flag) when you add your Discourse board to the Home Screen, Android will:
- Create an APK on the fly for your site and install it on your phone
- Create a intent so everytime you click on a link to your forum on any app, email or website it will prompt to open on your new app
- Since it’s an app, it will be avaliable on your app launcher, instead of only the home screen (more Android-like)
- Use a bigger logo
