I'm guessing you have an iPhone, what you can do is restart your phone, by holding the power button on top, and the home button together for about 20 seconds, you'll see the phone screen go black, keep holding it, and then the apple logo comes up, and then let go. Once everything comes back up, try to download it again from the App Store.
