How do we sync data?
Launching the App or bringing it to the foreground on your device, accompanied by a press of the crown of the watch will typically initiate a sync with your watch. If your watch doesn’t start syncing automatically after a few seconds, make sure Bluetooth is enabled on your phone and try moving your watch closer to your phone. If your watch and phone are already a few centimeters apart, try giving the crown on your watch a press to wake up the Bluetooth radio.
If you continue having trouble syncing, quit the App and turn your device’s Bluetooth setting off and back on again. If this does not work, turn off your device and re-start it.
Smartphones and tablets, like computers, need to be rebooted periodically to function optimally. Also verify your phone or tablet is above 20% battery level. Several devices will conserve power when battery drops under 20%.
