Does ALPHA 2 have GPS?
ALPHA 2 does not have GPS. It uses an internal accelerometer to detect your steps and provides estimates for speed, pace, and distance.
If you'd like more accurate speed and distance data you can connect your ALPHA 2 as a heart rate sensor to fitness apps, and use the GPS in your phone to record your workout. Some favorite apps are MapMyRun, Strava, Endomondo, and RunKeeper.
