More accurate than iOS app...
... except in my car, where its about 180 degrees off. I know this app uses the same sensors as the native app, but GPSCompass is more accurate out in the open. Id give it more stars if it maintained the settings, but I have to reselect true north and Imperial units every time I use it.
