Did you know an app icon can be created for any website and added to the Home Screen?
Tap near the bottom in Safari to reveal the toolbar. Tap the share button (a square with an upward arrow) followed by the Add to Home Screen option.
Some websites supply an icon; for others, a shot of the current view is used. Tapping the icon on your Home Screen launches Safari and takes you to the website directly.
Progressive Web Apps
This technique isn’t just for websites. Some entire apps are hosted on the developer’s website and can be used without installing anything from the App Store. These are called Progressive Web Apps and can be added to your Home Screen using the tip above. These apps are optimized for mobile use and take up the full screen, hiding any Safari overlays.
