iPhones and iPads:
Launch the Safari browser on Apple's iOS and navigate to the MMG at psvmmg.org. 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. Tap the Add to Home Screen icon in the Share menu.
Android Phones and Tablets:
Launch Chrome for Android and open the MMG website at psvmmg.org. Tap the menu button and tap Add to homescreen.
