A new feature in Google Chrome "turns" websites into apps

the Google Testing a new option that improves the way you add websites to your Android home screen via Google Chrome.

The popular browser currently has two options for adding a website to the home screen on your Android phone.

First, you can simply create a shortcut. On any website, Chrome supports “add to home screen” via a button in the full menu. This option works with literally anything and just adds a shortcut to the home screen that opens in Chrome.
The second option only appears on sites that run as a Progressive Web App. The “Install” button appears instead of the “Add to Home Screen” option. This means that you can only have one choice.

In many cases, Progressive Web Apps may look like native apps on your device. However, they are installed in a very different way. Instead of going through the traditional app store, the process is handled by your browser.

the Google He seems to know that Showing users only one option or the other can be confusing. A unified interface is now being tested. As spotted by WindowsReport, the latest Canary build of Chrome for Android has a new flag to enable the “PWA Universal Install” feature.

Once enabled, you'll find an expandable Add to Home Screen button in the full menu on all Chrome websites. Clicking on it will give you a choice between a home screen shortcut and a PWA, possibly depending on availability. This is a welcome change that gives users more flexibility and eliminates confusion.

This isn't fully operational yet, but it shows Google's plans.
