If you’re one of those paranoid people that live in fear of someone looking through their phones, then the heat sensitive iPhone backing will prove to be your greatest ally against an invasion of privacy. While a security code on your phone serves as good preventative measure, if a friend or significant other learned it, they would have unlimited access with no proof to back your suspicions; the heat sensitive backing on the other hand will leave physical evidence.

With all the iPhone covers on the market, go with one that will not only stand out but actually provide more use than just matching your outfit or accessories. Having been laser cut for the perfect fit, the backing is applied like a giant sticker over the iPhone. It’s also just .005″ thick so it will create no bulk in the pocket and also lets you put a protective case over it if you wish. The sticker reacts to temperature changes in between 95 to 90 degrees Fahrenheit and create combinations of blue and green hues that give your iPhone a truly neat look.
