Make your app installable on phones - shippingszn launch readiness

A tiny /manifest.json plus proper-sized icons lets people add your site to their phone's home screen with one tap. When they launch it, it opens full-screen — no browser URL bar in the way — like a real app. Zero app-store submission needed.

Most AI-built sites stop at the default favicon and never get installed. Users who add your app to their home screen return two to three times more often than bookmark-only users — and it's a 30-minute setup to enable it forever. Also closes the subtle credibility gap of a generic browser favicon on your production URL.

The shippingszn CLI includes automated checks for this launch-readiness control.

The Launch Fix Kit keeps scan-specific findings, file and line evidence, AI-builder punch-list tasks, and verification steps tied to the paid report.

Generate your icon set: at minimum a 512×512 PNG, a 192×192 PNG, a 180×180 apple-touch-icon.png, and a favicon.ico or favicon.svg. Transparent backgrounds.
Create a /manifest.json with your app name, short name (≤12 chars), start URL, standalone display mode, theme color, and the icons.
Link it from <head>: <link rel="manifest" href="/manifest.json"> plus <meta name="theme-color" content="#yourbrand">.
Add <link rel="apple-touch-icon" href="/apple-touch-icon.png"> and <link rel="icon" href="/favicon.svg"> pointing at your icons.
Open Chrome DevTools → Application → Manifest and confirm every field validates with no warnings.
