Had been questioning that my heart rate was as low as it was and then I noticed that the device is showing much lower than what the app is showing. I ha e them in sync. How do I calibrate the heart rate? See pics atraches. They were taken within seconds if one another.

Try a restart by holding the left and bottom right buttons for about 10 seconds until you see the Fitbit logo. That should fix most problems.
