How to remove location on Iphone app?

I accidently clicked "Okay" to allow my location to be used on the 5-0 Scanner app for the Iphone. How do I go about disabling it?

Go on settings - privacy - location services and scroll down and you should see a list of apps you have enabled and disabled the location settings of, find the app on the list and switch it off.

Chop a vital part of your Iphone off! This will have the desired effect of disabling it!
