# Meet PWA installability criteria
Installable PWAs appear in the browser's address bar install prompt and in app stores, giving users a native-app experience without an app store listing. Studies consistently show that installed PWAs have higher engagement and retention than browser-only equivalents — users who install spend 3× more time in the app on average.
## Quick Reference
- Serve the app over HTTPS (required by browsers)
- Link a valid web app manifest with name, icons, start_url, and display
- Provide a 192×192 and 512×512 icon; add a maskable variant for Android
- Register a service worker that responds with 200 when offline
## Check
Check whether this site meets the PWA installability criteria: HTTPS, valid manifest, service worker, and appropriate icons.
