Hi there, @MAS7. Thanks for stopping by in the Fitbit Community Forums. I'm sorry to hear that your Versa 2 is not tracking your heart rate accurately. I understand where your concern is coming from.
As with all heart-rate tracking technology, accuracy is affected by personal physiology, device location on your arm, and type of movement. For a more accurate heart-rate reading:
- Wear your Fitbit device on top of your wrist, and make sure the back of the device is in contact with your skin.
- When you’re not exercising, wear your device a finger’s width above your wrist bone.
- During exercise, wear your device a bit tighter and higher for an improved fit. The band should be snug but not constricting (a tight band restricts blood flow, potentially affecting the heart-rate signal). Many exercises such as bike riding or weight lifting cause you to bend your wrist frequently, which could interfere with the heart-rate signal if the watch is lower on your wrist.
To resolve common issues, make sure you've followed our troubleshooting steps in What factors can affect my heart-rate reading on my Fitbit device?
