You can find directions without a magnetic compass, as long as there is sunlight. Hold your finger upright at the center of the screen and turn your device. Just line up the white line with your finger's shadow, and the correct directions are shown. It needs neither GPS nor a network connection and works completely standalone. Just make sure your device's clock is set correctly.
