What's sleep score in the Fitbit app?

Your sleep score helps you understand your sleep each night so you can monitor trends in your sleep patterns. Studies show getting enough high-quality sleep can positively affect your energy, activity, mood, weight, and more (source).

Your overall nightly sleep score is based on your heart rate, the time you spend awake or restless, and your sleep stages.

Note: Your device needs to track sleep stages to determine your sleep score. For more information, refer to What should I know about Fitbit sleep stages?

Your overall sleep score is the sum of your individual scores for time asleep, deep and REM sleep, and restoration, for a total score of up to 100.

To see your score breakdown (available with a Fitbit Premium subscription):

1. From the Today tab in the Fitbit app, tap the Sleep duration tile.
2. Tap the Sleep score tile.

Metric	Description	Total possible points
Time asleep	This metric compares the time spent asleep and awake with your goal. When you spend more time asleep, this score will be higher. To check your time asleep and awake: From the Today tab in the Fitbit app, tap the Sleep duration tile. Your time asleep compared to your goal appears at the top of the screen.	50
Deep & REM	This metric checks the amount of time you spent in deep and REM sleep. The more time you spend in these sleep stages, the higher your score. To check your deep and REM sleep: From the Today tab in the Fitbit app, tap the Sleep duration tile. Check the sleep graph for the amount of time you spent in each sleep stage.	25
Restoration	Restoration is calculated by looking at your movement during sleep, as well as your sleeping heart rate. A high sleeping heart rate or excessive tossing and turning can lower your score. To check your restlessness and sleeping heart rate (available with a Fitbit Premium subscription): From the Today tab in the Fitbit app, tap the Sleep duration tile. Swipe up to check the information shown below the sleep graph. Your average sleeping heart rate is listed in the More about your sleep section, and the percentage of time you spent restless is listed in the Restlessness section.	25

Your individual score for each metric are added together to give your overall sleep score. The average score ranges from 72 to 83. Sleep score ranges are:

Sleep score	Range
Excellent	90-100
Good	80-89
Fair	60-79
Poor	Less than 60

Restoration provides insight into how restful your sleep was. This part of the score is based on your sleeping and resting heart rates and how much time you spent tossing and turning. You receive a higher restoration score when your sleeping heart rate is lower than your daytime resting heart rate.

To get a detailed breakdown of your restoration score in the Fitbit app, purchase a Fitbit Premium subscription. For more information, refer to What should I know about Fitbit Premium?

Your sleeping heart rate, which is your heart rate while you’re asleep, is often lower than your resting heart rate. For more information about resting heart rate, refer to How do I track heart rate with my Fitbit device? Factors such as caffeine, alcohol, stress, illness, or other actions can impact your sleeping heart rate (source).

To check your sleeping heart rate in the Fitbit app, purchase a Fitbit Premium subscription. For more information, refer to What should I know about Fitbit Premium.

Your resting heart rate is the number of times your heart beats per minute when you are still and well-rested. Your resting heart rate is estimated each day. Your sleeping heart rate is detected continuously throughout the night.

Wrist-based Fitbit devices and Google Pixel Watch series automatically detect your sleep when you wear your device to bed. Make sure your device’s battery has enough charge remaining to last through the night.

To help improve your sleep score, work on your overall sleep habits, heart health, and activity levels:

• Exercise earlier in the day or at least 3 to 4 hours before you sleep (source).
• Maintain a consistent sleep schedule (source). For more information, refer to How do I track my sleep with my Fitbit device?
• Meet the CDC’s recommended 150 active minutes per week (source).

For additional tips to improve your sleep routine and quality, refer to How can I use my Fitbit device to sleep better?

If you edit a sleep log, for example, if you change the time you woke up, your sleep score adjusts accordingly. For more information on editing your sleep log, refer to How do I add, edit, or delete Fitbit data and activities?

In order to get a sleep score, you need to receive sleep stages. If you didn’t get sleep stages, refer to What should I know about Fitbit sleep stages?

If you have sleep stages but can't find a sleep score:

• Note that it may take a few minutes for your sleep score to appear.
• Update the Fitbit app to the latest version. For instructions, refer to How do I use the Fitbit app?

You can’t turn off your sleep score at this time.

You can download your sleep data at any time. Note that you’ll receive raw data without further analysis. For instructions on how to download your data, refer to How do I export my Fitbit data?
