A progressive web app can be installed straight from the browser. Some audiences, however, look for apps only in the store. For Android there is an official route: the Trusted Web Activity. It does not wrap a website in its own browser component but opens the PWA full-screen in the installed Chrome, without an address bar.

For the address bar to be hidden, it must be proven that the app and the website belong to the same provider. A file on the website confirms the app’s signing key. Without this confirmation Chrome shows the address bar again, and the app looks like a website.
Tools
Tools such as Bubblewrap or PWABuilder generate an Android project from the web app manifest that can be uploaded to Google Play as an app bundle. Content updates still happen through the website; a new app bundle is needed only when the wrapper changes.
No equivalent for iOS
There is no comparable mechanism for Apple’s App Store. An iOS app needs a native wrapper, and Apple’s guidelines reject apps that essentially package a website without offering additional app functionality. Anyone who must be present in the App Store therefore needs a genuine native or cross-platform app.
When a TWA makes sense
A TWA pays off when a PWA already works well and an Android audience expects the store. It does not change the app’s capabilities: what is impossible in the browser is impossible in the TWA too. Whether PWA, TWA or native app is the right form factor is clarified by our app form factor check or an app concept.
