Real-time GPS speed — works best outdoors for cycling, running, and driving.
—
km/h
Works best outdoors. GPS speed is most reliable at cycling and driving speeds (10+ km/h) with a clear view of the sky. Walking pace is near the detection limit on most devices, and indoor GPS signal is too weak for accurate speed readings.
Accuracy is shown by the ±m figure while tracking — under 15 m is good, over 30 m means the signal is too weak for reliable readings. The screen stays on while tracking.
