Why it matters
Evidence
Web app manifest declared
✗ 0/745 pages
A web app manifest is required for installability and controls how the app appears when launched.
—
Service worker registered
✗ 0/745 pages
A service worker is what makes offline access, caching, and background sync possible.
—
Theme color declared
✗ 0/745 pages
Theme color controls the browser chrome/status-bar color when the site is installed or bookmarked.
—
Apple touch icon (iOS/bookmark icon)
✗ 0/745 pages
iOS uses this icon for home-screen bookmarks and "Add to Home Screen" — without it the icon falls back to a screenshot.
—
Manifest fetched and parsed successfully
✗ 0/745 pages
A manifest that fails to parse cannot drive installability or launch behavior even if the link is present.
