Heart rate not working

[Amber87777]

When I try to check my bpm, it’s always at nothing. It’s never shown me a figure. Also, last two nights It hasn’t shown detailed information for my sleep. Just got this Fitbit, had the Alta before. Are there any ways to customize clock face or anything on actual Fitbit itself?

Nice to see that you're digging into the Forums @Amber87777, let me give you a warm welcome to our Community. 

Thanks for reporting the issues with your new Inspire HR not showing your BPM. I'd consider restarting it with the following steps:

1. Plug the charging cable into the USB port on your computer or any UL-certified USB wall charger.
2. Hold the other end of the charging cable near the port on the back of the tracker until it attaches magnetically. The pins on the charging cable must connect securely with the port.
3. Press and hold the button on your tracker for 5 seconds. 
4. Release the button. When you see a smile icon and the tracker vibrates, the tracker restarted.

Your tracker should now work normally. Please confirm that the heart rate feature is "On" and check if you can see the green LED lights on the back of your Fitbit.  

Open the Settings app  > Heart Rate > Off

To see your heart rate on Inspire HR, swipe up from the clock screen to see your real-time heart rate and heart-rate zone. You can also check more details about HR on page 40 in the manual.

There is no option to customize clock faces but you will find the instructions on how to change the clock face of your Inspire HR here: How do I change the clock face on my Fitbit device?

Let me know if you need anything else.

I'll be around.
