NavPro is a GPS navigation program which tracks speed, time, and distance. ++ Also indicates course heading and latitude/longitude. ++ Acceleration response is optimized for biking, hiking, sailing and similar activities. ***Note, this makes the response appear slow if you test it in an automobile, but it provides much more accurate readings for low-acceleration activities.*** Data filtering for greater accuracy. ++ Course heading dial indicates direction of motion (note - it does not respond like a compass to the device's orientation; rather, it indicates the direction in which you are traveling). ++ Link to launch map of current location. ++ While tracking, prevents the device from going into sleep mode -- returns to normal timeout when stopped / paused, or when minimized to 'card' mode. ++ Displays in English or metric units. ++ Displays current, maximum, or average speed. ++ Future updates to include trip logging and mapping. ******* Buy now at the introductory price and get the updates for free!
