To install the app on an iPhone, you can follow these steps:

1. Open Safari: PWAs can be added to your iPhone's home screen using the Safari browser.

2. Navigate to the PWA: Go to the website or web application that you want to install as a PWA using Safari.

3. Add to Home Screen:

   • Tap the "Share" button located at the bottom center or top right corner of your Safari browser window (it looks like a square with an arrow pointing upward).

   • Scroll down or swipe left in the share sheet until you see the "Add to Home Screen" option.

   • Tap "Add to Home Screen."

4. Customize the App Name (Optional): You can change the name of the app if you'd like. This name will appear under the app icon on your home screen.

5. Tap "Add": After customizing the name (or if you choose not to customize it), tap the "Add" button in the top right corner of the screen.

6. PWA Installed: The PWA will now be added to your iPhone's home screen as an app icon.

That's it! You've successfully installed the PWA on your iPhone. You can now launch it just like any other app from your home screen, and it will function similarly to a native app, even though it runs within the Safari browser. PWAs can work offline and provide a more app-like experience for web applications.
