A:Answer The Fre has a built in screen protector and the back of the case is a softer plastic, it feels a little cheap in my opinion. The Nuud does not have a built in screen protector, but it has a rubber ring around the inside of the case that goes around the screen to keep it waterproof, also the back of the case is clear, hard plastic, it has a sturdier feel than the Fre and allows you to see the phone.
