Tap the Share button on the browser’s toolbar — that’s the rectangle with an arrow pointing upward. It’s on the bar at the top of the screen on an iPad, and on the bar at the bottom of the screen on an iPhone or iPod Touch.
Once the Share menu pops up, tap the Add to Home Screen icon.
Please note that to do this you must be using the default iOS browser ‘Safari’.
Tap the menu button and tap Add to homescreen.
If you are using a different browser like Firefox for Android, then tap the menu button, tap the Page option, and tap Add to Home Screen.
That’s it! You can now access Discover Earth from your home screen.
