If your Fitbit is not showing REM sleep, there could be a few reasons why. Firstly, it's important to note that not all Fitbits support sleep staging. Only Fitbits with heart rate sensors can record your sleep stages. Additionally, your Fitbit needs to be worn on your wrist or arm and set to wrist mode to collect sleep stage information. Another reason could be that you did not sleep for long enough. Fitbits require at least 3 hours of sleep data to estimate your sleep stages. If you slept for less than 3 hours, your Fitbit won't record sleep stages and will only show basic sleep information. Additionally, if your Fitbit's battery is low, it may switch off sleep tracking to preserve battery life. Other potential reasons include a poor heart rate reading, a loose-fitting band, or using the Begin Sleep Now option in the app.
What You'll Learn
Fitbit device may not be syncing with the Fitbit app
If your Fitbit device is not syncing with the Fitbit app, there are several troubleshooting steps you can try.
First, ensure that your Fitbit device is not paired with any other phones or tablets. Open the Settings app on your phone and check the list of connected devices. If your Fitbit device is listed, remove it.

Open the Fitbit app, press and hold the screen, and pull down until you see a progress bar at the top of the screen. Release your finger and wait for the progress bar to fill.
Check your phone's Bluetooth and internet access. Reset Bluetooth by turning it off and back on again. Also, ensure that your phone is connected to cellular data or Wi-Fi, as the Fitbit app needs internet access to sync.
If your Fitbit device still isn't syncing, try restarting your phone. After your phone restarts, open the Fitbit app and try syncing again.
Update your phone, Fitbit app, and Fitbit device. Check for any pending updates and install them.
Check your phone permissions. On Android phones, go to Settings > Permissions and ensure that Location and Nearby Devices are turned on. On iPhones, go to Settings and ensure that Background App Refresh and Location Services are enabled.
If your Fitbit device still isn't syncing, try charging it. If that doesn't work, you may need to unpair and re-pair your Fitbit device. On iPhones, go to Settings > Bluetooth, tap the info button next to your Fitbit's name, and choose "Forget This Device". Then, open the Fitbit app and follow the prompts to reconnect.
If you've tried all of these steps and your Fitbit device still isn't syncing, you may need to contact customer support for further assistance.

Fitbit battery is critically low or depleted
If your Fitbit device's battery is critically low or depleted, it may not be able to track your sleep patterns and sleep stages. This is because the device needs to be able to track your heart rate and movement patterns to estimate your sleep stages. When the battery is low, the device may switch off sleep tracking to preserve its battery.
To ensure that your Fitbit is tracking your sleep accurately, it is important to check the battery level before going to bed and ensure that it is sufficiently charged. If time is short, charging your Fitbit for 20-30 minutes before you go to sleep should provide enough battery life to last through the night.
In addition to checking the battery level, there are a few other steps you can take to troubleshoot sleep tracking issues. These include:
- Syncing your Fitbit with the app after waking up
- Cleaning the Fitbit sensors to remove any dirt or grime that may impede data gathering
- Wearing your Fitbit higher on your wrist or on the inside of your arm
- Changing the sleep sensitivity settings
- Avoiding using the "Begin Sleep Now" option in the app
- Restarting your Fitbit
- Creating a manual sleep log or editing an existing one
By following these steps, you can help ensure that your Fitbit is accurately tracking your sleep patterns and sleep stages.

Fitbit is not worn correctly
If your Fitbit is not worn correctly, it may not be able to track your sleep stages accurately. Here are some tips to ensure your Fitbit is worn correctly for optimal sleep tracking:
Wear your Fitbit higher on your wrist: Place your Fitbit about 2-3 finger widths above your wrist bone. This position allows for a more consistent heart-rate reading.
Adjust the band for a secure fit: Ensure the band feels snug and secure on your wrist, but not too tight. A tighter fit can improve heart-rate tracking and reduce the chances of your Fitbit moving around during sleep.
Avoid using the "Begin Sleep Now" option: Instead of manually starting sleep tracking through the app, simply wear your Fitbit to bed. Automatic sleep tracking seems to provide more reliable data on sleep stages.
Sync your Fitbit in the morning: After waking up, remember to sync your Fitbit with the app to view your sleep statistics. You can manually sync your device by holding and pulling down on the Today tab in the app or by going to the Devices icon and selecting your Fitbit model.
Clean your Fitbit sensors: Regularly clean the back sensors of your Fitbit to remove any dirt, oil, or grime that may impede data gathering. Use only fresh water and a soap-free cleanser to avoid residue that could affect sensor performance.
Avoid direct contact with lotions and tattoos: Skin lotions and tattoos can reduce the effectiveness of the sensors. Keep your Fitbit away from recently lotioned skin or tattooed areas.
Wipe down your Fitbit after workouts: Sweat can leave salts and oils on your device, affecting sensor accuracy. Always wipe down your Fitbit after a sweaty workout, paying extra attention to the sensors.
Try wearing your Fitbit on your non-dominant hand: If you're not getting good readings, try wearing your Fitbit on the inside of your non-dominant wrist or arm. This position can provide a more accurate heart-rate reading and improve sleep tracking.
Ensure your Fitbit is in wrist mode: Some Fitbit models, like the Inspire series, have a clip mode that turns off heart-rate sensors. Make sure your device is set to wrist mode to enable heart-rate tracking and sleep staging.

Fitbit user slept less than 3 hours
If your Fitbit device is not showing REM sleep, there could be several reasons for this. Firstly, it is important to note that sleep stages are only available on Fitbit devices with heart-rate tracking capabilities. Additionally, the device must be worn on the wrist or arm, with wrist mode enabled, to collect heart rate data during sleep.
One possible reason for the absence of REM sleep data is the duration of your sleep. Fitbit requires at least 3 hours of sleep data to estimate and provide sleep stages, including REM sleep. If you slept for less than 3 hours, your Fitbit will only display basic sleep information such as time asleep, restless, and awake.
Another factor to consider is the positioning and fit of your Fitbit. Ensure that you wear your device snugly, approximately 2-3 finger widths above your wrist bone. This positioning ensures optimal heart rate tracking during sleep. Additionally, avoid manually starting sleep tracking through the "Begin Sleep Now" option in the app, as this may interfere with the collection of detailed sleep data.
It is also important to maintain proper device hygiene. Clean the sensors of your Fitbit regularly to prevent the buildup of dirt, oil, or grime, which can impede data collection. When cleaning, use only fresh water and a soap-free cleanser to avoid residue that may impact performance.
Lastly, check your device's battery level and heart rate settings. A low battery may cause sleep tracking to be disabled, and inconsistent or absent heart rate data can affect the accuracy of sleep stage estimation.

Fitbit is not in wrist mode
If your Fitbit is not in wrist mode, it will not be able to track your sleep stages and generate a sleep score. This is because the sleep score is calculated using data from the sleep stages, which include REM, light, and deep sleep.
To ensure your Fitbit is in wrist mode, follow these steps:
- Open your Fitbit's Quick Settings.
- Verify that your device is set to wrist mode. If it is on clip mode, tap it to change it to wrist mode.
By setting your Fitbit to wrist mode, you ensure that the heart rate sensors are active and can track your sleep stages accurately. This is important because the sleep score is dependent on this information.
Additionally, it is recommended to wear your Fitbit higher on your wrist, about two fingers above the wrist bone, to get more accurate readings. This is because the sensors need to be in contact with the skin to track your heart rate effectively.
If you own a Fitbit Inspire 3, 2, or the original Inspire, it's important to note that these models have a clip mode. While the clip mode offers convenience, it turns off the heart rate sensors. As a result, your Fitbit can only record sleep in the general categories of awake, restless, and asleep since it doesn't record heart rate data in clip mode.
Therefore, it is crucial to ensure your Fitbit is set to wrist mode before going to bed to get the most accurate sleep tracking and receive your sleep score.
