Runs in your browser — pin it like an app
Crontab Guru is a regular web app, not a PWA, so it won't offer an install button. Your browser can still pin it with its own icon and window:
- Open crontab.guru in Chrome or Edge.
- Chrome: ⋮ menu → “Cast, save, and share” → “Install page as app…”. Edge: ⋯ menu → “Apps” → “Install this site as an app”.
- Open the app in Chrome on Android.
- Tap the ⋮ menu → “Add to Home screen” → “Add”.
- Open the app in Safari on iOS.
- Tap the Share button → “Add to Home Screen”.
Pinning gives you a shortcut in an app-style window; offline use and notifications stay up to the publisher. What “Non-PWA” means →
