FREQUENTLY ASKED QUESTIONS
  • What mobile devices are supported for syncing?
  • How do I charge my flex?
    • Your tracker battery lasts for about 5 days. To charge it, remove the tracker from the band and place it in the charger until all 5 lights are solid.
    • If you are having trouble, your tracker's charging contacts may be obstructed by microscopic dirt or debris that prevents them from making a good connection to the charger. Use hand sanitizer and a tissue or dampen a cotton swab with rubbing alcohol and carefully clean the charging contacts on your tracker. Do not submerge your tracker in water or use abrasive cleaners. Thoroughly dry your tracker before attempting to charge. Be sure to fully seat your tracker into the charger, with the charging contacts fully inserted into the charging cable enclosure.
  • How do I reset my tracker?
    • lf your tracker is not responding, it may be fixed by restarting.
    • 1. Plug your charging cable into the USB port and insert your tracker into the charging cable.
    • 2. Insert a paperclip into the small pinhole on the back of the charger.
    • 3. Press on the pinhole for 3-4 seconds.
    • Your Flex will now be reset. Take your tracker out of the charger and insert it back into the wristband.
  • Can the wristband irritate my skin?
    • The Flex wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. It does not contain latex. The clasp is made of surgical-grade stainless steel and contains traces of nickel. As with any type of jewelry, some people may experience allergies. Numerous factors can cause an allergy, such as a nickel sensitivity, reactions to bacteria that can accumulate in watch wristbands or other wearable devices, a reaction between the wristband and your soap or perspiration, or an allergy to the material of the wristband. If you notice any signs of skin irritation or experience any discomfort, please discontinue use.
