One install button, different browser instructions.
The app now detects the browser and either opens the native install prompt or explains the manual steps.
Click Install app. If the browser supports PWA install, the native install prompt opens immediately.
Use Install app from the button when available, or open the browser menu and choose Add to Home screen.
Tap Share, choose Add to Home Screen, then tap Add. Apple does not always show an automatic install prompt.
Firefox has limited PWA install support. Use the browser menu if Add to Home Screen is available, or open from bookmarks.
On supported desktop browsers, install from the button or the install icon in the address bar.
The installed app shows a friendly offline page if internet drops. Live transactions still need reconnection.
Use HTTPS when hosted online.
PWA installation and service workers work properly on secure domains. Localhost works for testing, but your public mobile app link should be your hosted domain.
