How does my Fitbit device automatically detect sleep?

All wrist-based Fitbit devices automatically detect your sleep when you wear your device to bed. We recommend wearing your device in a snug wristband while sleeping; don’t wear your device in a clip or pendant accessory.

When your body is completely at rest and you haven’t moved for about an hour, your Fitbit device records that you’re asleep. 

What sleep information does my Fitbit device track?

If your device doesn’t track heart rate, you see your sleep pattern in the Fitbit app. Your sleep pattern includes your time spent awake, restless, and asleep. Restless sleep indicates that you moved in your sleep, like tossing and turning. If your device detects excessive movement—enough that restful sleep would not be possible—your device records time spent awake. 

Fitbit devices that track heart rate (except Charge HR and Surge) also track sleep stages. For more information, see What should I know about sleep stages?

How do I see my sleep information?

Sync your Fitbit device each morning to see last night's sleep stats, including sleep score, on your wrist or in the Fitbit app.

How do I see my sleep log data?

  • iPhones, iPads, and Android phones
    1. In the Fitbit app, tap the Today tab User-added image, then tap the sleep tile User-added image.
    2. Tap Today or another day to see details.

    1. From the Fitbit app dashboard, tap the sleep tile.
    2. Tap Today or another day to see details.

    2. Check the sleep tile to see your sleep information. You may have to swipe up to find it. If you don't see the sleep tile, tap Settings at the bottom of Fitbit Today and make sure you turned on the sleep tile.
    3. Swipe left on the sleep tile to see your patterns or time spent in each sleep stage, and your sleep history for the past week.

Can I see my average sleep stats?

See your averages for the week or longer periods of time for certain sleep stats, including: 
  • Hours slept—The number of hours you slept each night that week and your weekly average 
  • Sleep score—Your sleep scores throughout the week and your weekly average score
  • Sleep schedule—An overview of your sleep schedule that week (when you went to bed and when you woke up)
  • Sleep stages—The number of hours you spent in each sleep stage each night that week and your weekly average minutes asleep 
  • iPhones, iPads, and Android phones
    1. In the Fitbit app, tap the Today tab User-added image, then tap the sleep tile User-added image.

    3. Swipe right to see data from previous weeks. 
    4. Tap a length of time at the top to change the time period you see averages for. For example, tap 1 mo to see your sleep data by the month and your monthly averages.  
  • On-device
    1. Swipe up from the clock face to see Fitbit Today.
    2. Check the sleep tile to see your sleep information. You may have to swipe up to find it. If you don't see the sleep tile, tap Settings at the bottom of Fitbit Today and make sure you turned on the sleep tile.
    3. Swipe left on the sleep tile to see your sleep history for the past week.

How is my time asleep calculated in the Fitbit app?

Your time asleep is calculated by subtracting your time spent awake and restless from your overall tracked sleep time. For example, if you slept 8 hours but woke up 2 times for 15 minutes each, your time asleep would be 7 hr 30 min.

To learn more about your time asleep in sleep stages, see What should I know about sleep stages?

How do I set or change my sleep goal in the Fitbit app?

For instructions, see How do I track my health and fitness goals with the Fitbit app? Note that the CDC recommends adults get at least 7 hours of sleep each night (source).

How do I set a sleep schedule in the Fitbit app?

Set a sleep schedule in the Fitbit app to help you meet your sleep goal and maintain consistent sleep patterns. You can set either a bedtime or a wake-up time target, or set both targets. 

If you meet your target by going to sleep or waking up within 30 minutes of the target, a star appears in the sleep schedule graph. You won’t see a star If you set both bedtime and wake-up time targets but only meet one.

How does Fitbit estimate how much sleep I need?

If you have 5 or more sleep logs, your sleep goal is estimated based on an average of these logs. Your wake-up time target is estimated based on the time you typically wake up each day, and your bedtime target defaults to the time you should go to sleep in order to meet your sleep goal. 

If you have fewer than 5 sleep logs, you can provide an estimate of how much sleep you get on a typical night, and your sleep goal is set based on this estimate. You must manually set your bedtime and wake-up time targets.

To manually set or adjust your sleep goal, see How do I set or change my sleep goal in the Fitbit app? To manually set or adjust your bedtime and wake-up time targets, see How do I set or change my bedtime or wake-up time targets?

How do I set or change my bedtime or wake-up time targets?

    1. Tap the Today tab User-added image, then tap the Sleep tile User-added image
    2. Tap the gear icon in the top right.
    3. Set or edit your targets. To remove a target, tap the three dots in the top right.
    4. Tap Done.
  • Windows 10 devices
    1. From the Fitbit app dashboard, tap the Sleep tile User-added image
    2. Tap the moon icon on the bottom.
    3. Set or edit your targets. To remove a target, tap the three dots in the bottom right. 
    4. Tap Save.

How do I set a bedtime reminder in the Fitbit app?

Set a bedtime reminder in the Fitbit app to help you maintain a consistent sleep schedule. When it's time to wind down for bed, you receive a notification on your phone. On certain Fitbit devices, you can also see a bedtime reminder on your device.

To start, you receive bedtime reminders on Sunday through Thursday (common work or school nights). To change which days you receive a bedtime reminder: 

  • iPhones, iPads, and Android phones
    1. In the Fitbit app, tap the Today tab User-added image, then tap the sleep tile User-added image.
    2. Tap the gear icon in the top right.
    3. Turn on the bedtime reminder and set the time and frequency.

    To see a reminder on Fitbit Charge 3, Fitbit Ionic, and Fitbit Versa series, make sure notifications from the Fitbit app are turned on. For instructions, see How do I get notifications from my phone on my Fitbit device?

  • Windows 10 devices
    1. From the Fitbit app dashboard, tap the sleep tile.
    2. Tap the moon icon on the bottom.
    3. Find the option to turn on bedtime reminders and set the time and frequency.

    To see a reminder on Fitbit Charge 3, Fitbit Ionic, and Fitbit Versa, make sure notifications from the Fitbit app are turned on. For instructions, see How do I get notifications from my phone on my Fitbit device?

Can my Fitbit device log a nap?

Your Fitbit device detects and records naps that are at least an hour long. 

How do I edit my sleep history in the Fitbit app?

Edit or delete sleep logs in the Fitbit app. For instructions, see How do I add, edit, or delete Fitbit data and activities?

What's the difference between the normal and sensitive sleep setting?

For devices that record sleep patterns instead of sleep stages, you can set your device to track sleep in a normal or sensitive mode.

In normal mode, when you make significant movements like rolling over, your device records time spent awake. This setting is appropriate for most users. In sensitive mode, your device records nearly all movements as time spent restless or awake. This setting may be helpful if you wake up feeling tired even though your sleep history shows sufficient rest.

To change your sleep sensitivity setting:

  • iPhones & iPads
    1. In the Fitbit app, tap the Today tab User-added image, then tap your profile picture. 
    2. Tap Advanced Settings > Sleep Sensitivity and make your changes.
  • fitbit.com dashboard
    1. From the fitbit.com dashboard, click the gear icon User-added image > Settings > your device image.
    2. Click Sleep Tracking and make your changes.

    Note: On Android phones, you must change your sleep sensitivity setting on fitbit.com.

    How do I manage sleep insights in the Fitbit app?

    Sleep insights in the Fitbit app provide personalized guidance on how to improve your sleep for better overall health.The more sleep you log, the more insights you’ll receive, but you may not receive a new insight each day. 

    To start, sleep insights are turned on. To turn them off:

    • iPhones, iPads, and Android phones
      1. In the Fitbit app, tap the Today tab User-added image, then tap the sleep tile User-added image.

      3. Find the option to turn off sleep insights.
    • Windows 10 devices
      1. On the Fitbit app dashboard, tap the sleep tile.
      2. Tap the moon icon on the bottom.
      3. Find the option to turn off sleep insights.
