Buying a Fitbit wearable with a built-in heart rate sensor is a wise investment. Such devices can let you know your resting heart rate, perhaps the best indicator of your health and fitness. They also allow you to heart rate zone train.
But sometimes things go wrong and the otherwise trusty device on your wrist stops tracking heart rate and the lights below on the sensor don’t flash. Here’s what to do.

Whenever you experience a problem with a Fitbit device, the first thing to do is to give it a good old restart. This is the go-to solution if the screen on your wearable is unresponsive, if it’s not connecting to the app or if it is not tracking your activity. If you’re not sure how to do this, check out our guide on how to reset your Fitbit fitness tracker or smartwatch.
This may or it may not solve the problem. If it didn’t work the first time around, it’s worth trying 2 or 3 times before giving up.
The next thing you can do is charge the battery to full capacity. This is because the heart rate tracking problem may appear if the battery is critically low as the sensor may switch off automatically.
It may seem kind of obvious, but also double-check that you have heart rate tracking switched on! If you have a Charge 3, Blaze, Ionic, Inspire HR or Versa, this is done by opening the Settings app on the watch and tweaking the option to “On” (“On” or “Auto” for Blaze) . For Alta HR and Charge 2, make sure the heart rate setting is set to “Auto”.
It’s also a good idea to have a look at how you’re wearing the device. If your Fitbit doesn’t have good contact with the skin it won’t be able to reliably track heart rate.
Hopefully one of these solutions has fixed your problem. If not, there may be a bug in the software. Rest assured that Fitbit is working hard to come up with a fix. The final alternative is that your device may be faulty. It’s best to contact Fitbit Customer Support if you suspect this is the case.
