North-up heading dial. Hold the device flat.
Course is the direction of travel relative to true north. A device compass may use magnetic north; these references can differ. Relative orientation is never treated as a compass.

Map loads when internet access is available. Location availability depends on the device. Map tiles require internet access.
Map tiles use OpenStreetMap when online. Recorded GPS points remain local to this device.
