When everything is working properly, your Fitbit works effortlessly in the background, syncing with your phone or computer and keeping you informed about your health and fitness data whenever you need it.

Of course, technology doesn't always work the way you expect, and you might occasionally find that your Fitbit stubbornly refuses to sync.

If you can usually sync but your Fitbit suddenly refuses to work, it's usually the result of a problem with your wireless connection, so toggling your device's Bluetooth can help. Performing a reset on the Fitbit or the device you're syncing with can also resolve a lot of common issues.

Before you try any specific troubleshooting for your phone or computer, make sure your Fitbit is charged. If necessary, place it on its charger for 30 minutes.

It might also be a good idea to restart your Fitbit to make sure it's working properly. The exact process for restarting a Fitbit varies by model, but for many models, you can place it in the charger and hold its side button until you see it restart. For specific instructions for restarting each model, you can see Fitbit's help article.

How to get your Fitbit to sync with your iPhone

If your Fitbit isn't syncing with your iPhone, try each of these troubleshooting steps. After each step, try to sync and see if that solved your problem.
