" summary

Progressive Web Apps claim that the web can behave like native apps by using service worker scripts to control caching, background updates and push notifications, requiring HTTPS and an app manifest; a crawl finds 1.5 million manifests on over 800,000 domains but many are junk so quality checks matter. Practical wins include Twitter Lite using a PWA approach to cut data usage to about a quarter and stores auto-converting good manifests to native packages (appx) so installs and updates work.
