Fitness Trackers Frequently Asked Questions (FAQs)

Consider this additional information when it comes to fitness trackers. 

Can I Rely On My Fitness Tracker to Track My Medical Condition?

No. None of these fitness devices are medical devices that can be relied on for diagnosing and monitoring medical conditions. Fitness trackers attempt to track information as accurately as reasonably possible but should never be relied upon. If you have concerns about your health, you should see a doctor.
