Pick a sport, hit start. Everything records offline — GPS, heart rate, splits — and syncs the moment you're back on a signal.
Heart rate, calories and time come straight from your watch. Distance stays at zero, and that's correct — nobody's cheating a treadmill.
Hold the button for two seconds. StrideX sends your exact coordinates, your route so far and your last known heart rate to your three safety contacts, and opens a call to 102.
