Compatible with:
• Fitbit Alta, Blaze, One, Flex, Force, Charge (HR), Surge, Ultra, and Zip
• If your Fitbit is paired to a phone, you will need to un-pair it (or power off the paired phone)
• Fitbit App "Always Connected" setting: Ensure this is not checked for app to work
• The Fitbit Zip needs to woken up by vibrations, as it goes dormant when inactive
• Temporarily uninstalling the Fitbit App may help, as a last resort
