Sleep score sometimes doesn't show up

[TomB29]

My Fitbit seems to pick and choose when it tracks my sleep score? I always get the rough estimate on hours slept, but some days it gives me a score, most days it doesn’t. I’ve tried resetting the device 3 times in a row. Changing some settings (as per other forums) but still doesn’t work. Can someone help?

thanks!

Hello @TomB29, welcome to the Community Forums! Thank you for the information and for the troubleshooting steps you've followed prior to posting!

You must see sleep stages to see a sleep score. For more information, see What should I know about Fitbit sleep stages?

If you sometimes don't see the sleep stages, please consider the following: 

1. If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
2. If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep with my Fitbit device?
3. If you slept for less than 3 hours.
4. If your device’s battery is critically low.

On a side note, it may take a few minutes for your sleep score to appear after you sync your Fitbit device. 

Keep me posted.
