The Gorilla Glass screens on iPhones are tough, but they aren’t invincible, so many people like to add a layer of protection to the screens. Many screen protectors are designed to protect more against scratching than impacts, but the Rhino Shield MK2 has a “shock-damping layer is able to take at least 5 times the impact energy of Gorilla Glass 2 on its own thanks to the unique polymer technology”. The shield is highly transparent and only 0.011″ thick, and it has a 3H hardness rating, which means it will also protect against scratches. It has an oleophobic coating and a silky smooth surface for easy on-screen sliding, touching, and tapping. The Rhino Shield MK2 is available in the US exclusively through BiteMyApple for $24.99 for the front screen of iPhone 4/4S or iPhone 5/5S/5C; you can cover both the back and front of the iPhone 4/4S for $29.99.
