A Trusted Web Activity is a way for Android applications to run a full-screen Chrome browser tab to render trusted web content.

What's different about a TWA?

A Trusted Web Activity runs a Chrome browser full screen in an Android app, meaning there is no browser UI visible in the app, including the URL bar. This is a powerful capability so we need to verify that the app and the site belong to the same developer - hence ‘Trusted’. To verify that the app and the site opened in the TWA belong to the same developer, a TWA uses Digital Asset Links to certify ownership. - Introducing a Trusted Web Activity for Android - Chromium Blog

Availability

Trusted Web Activities are available in Chrome on Android, version 72 and above. - Using Trusted Web Activities - Google Developers Updates
