1. Why doesn’t Fitbit show my heart rate?

Sometimes, your Fitbit tracker may have difficulty of getting a strong signal of your heartbeat. If you don’t see your heart rate on your tracker, you should make sure you wearing it correctly firstly. Try to place the tracker higher on your wrist, because blood flow in your arm increased the farther up you go. Moving your tracker a little bit up may be helpful. You have to make sure your tracker not wearing too tightly as well. If it is too tight, your blood flow will be restricted and the heat rate signal will be potentially affected.

If the steps above cannot let the tracker displaying the right data, try to set your Heart Rate setting from “Auto” to “On”. Then your tracker will be always active, instead of working when you’re moving. Remember that “On” mode increases battery usage, so it’s better to change it back to “Auto” when the signal is strong once again.

  1. I travel the same route every morning, Fitbit went from 9 floors to 1 floor. Also I think calories not correct & doesn’t display correct resting HB. I turned it off for an hour, back on, same problem. Any suggestions? Have had Fitbit for 8 months, is it under warranty?

  2. My fitbit was working yesterday and then the screen went white for the time and steps and heart rate. Now I cant turn it on at all. What should I do?
