Polaralign iphone 4s app problem

Not sure if this is the right place for this, but as there doesn't appear to be a search button this seems to be as good a place as any to try to resolve a problem with this app that I downloaded yesterday.

When I open the app it starts up and shows the revolving Apple loading up thingy, and states "Checking Location.." and after 4 or 5 seconds it turns off and goes back to the Apple screen. I have an iphone 4s, and I see in the settings that the app is only allowed to access the camera, and I assume it should also show it as being able to access my location. I can't see how this is enabled, can someone advise me please?

Oops. A bit premature with this post, I did another search elsewhere which gave me the answer straight away, sorry for the bother.
