A Progressive Web App (PWA) is an app that's built using web platform technologies, but that provides a user experience like that of a platform-specific app.
Like a website, a PWA can run on multiple platforms and devices from a single codebase. Like a platform-specific app, it can be installed on the device, can operate while offline and in the background, and can integrate with the device and with other installed apps.
Note
For this case, this app renders websites of your choosing using a webview technology.
An Android WebView is a system component that acts as an embedded "mini-browser" inside a mobile application, allowing developers to display web content directly within the app's layout
