Important Information About GPS

JH Tapped uses GPS to find your latitude and longitude when locating you on the trail map, when logging your runs, and when providing Fire Eagle with your position.

Display Accuracy

JH Tapped converts your latitude and longitude to a position on the trail map. Measurements of latitude and longitude are subject to error, and the trail map is not topographically precise. Your displayed location is approximate, and you should not rely on its accuracy.

When recording your runs and vertical distance JH Tapped also uses GPS to measure your altitude. Altitude measurements are less reliable than measurements of latitude and longitude.

Continuous Use

JH Tapped will not sleep while logging runs or sending position updates to Fire Eagle (it will sleep whenever you press the top button on your iPhone). Continuous use of GPS will drain your battery in a few hours.
