Location Services not Working – Gettysburg Battle App Review

My iPhone is set to disallow location services by default, but even after enabling this specific app, when the GPS option was selected, it still said location services would not work until I restarted the app...which I did multiple times. It would've been nice to have an app that showed where we were in the battlefield. Our Gettysburg trip is over and this app is as useful now as it was during our trip (sic).
