Fitbit Premium subscribers get access to more data, such as detailed information about the sounds you make at night
Fitbit Premium subscribers get access to a range of additional features and insights, including more detailed data about their sleep patterns and quality. This includes information about the sounds they make at night, such as snoring. The Fitbit app provides a sleep score, which rates the quality of sleep based on various metrics, including heart rate, movement, and sleep stages. This score is available to all Fitbit users, but Premium subscribers receive a more accurate and detailed breakdown.
The subscription costs $10 a month or $80 a year and includes personalized insights and recommendations about how to improve sleep quality. For example, if a user is not getting to sleep at the same time every night, they might receive a suggestion to build a sleep routine. Additionally, Fitbit Premium offers guided programs, advanced tools, and tailored workouts to help users reach their health and fitness goals. It also provides insights into how a user's behaviour impacts their health and personalized plans to help them achieve their goals.
For those with a Fitbit Sense or Versa 3 smartwatch, a Premium subscription also unlocks the snore detection feature. This feature uses the device's microphone to listen for snoring and other noises during the night, providing an overview of the noises made, the volume, and the frequency. This data helps to inform the overall sleep score, giving a clearer picture of sleep quality.
It is important to note that while Fitbit can track sleep and provide insights, it is not a medical device and cannot be used for diagnosis. However, the data it collects can be valuable for identifying potential issues, such as sleep apnea, and knowing when to seek medical advice.
To access Premium features, users can subscribe through the Fitbit app or the Google Store. The subscription can also be purchased through other stores or websites, and it is important to manage and cancel subscriptions through the original purchase platform.

Fitbit automatically tracks sleep stages, such as light, heavy, and REM sleep
Fitbit devices are mostly known for tracking fitness and activity. However, they can also monitor your sleep. All Fitbits can track the time spent asleep, restless, or awake. Additionally, every Fitbit with a heart rate monitor, except the Fitbit Surge and Charge HR, can automatically track sleep stages, such as light, heavy, and REM sleep. Fitbit uses a combination of movement and heart rate monitoring to track sleep. Certain Fitbits estimate these stages using "beat-to-beat changes in your heart rate," known as heart rate variability (HRV), which is known to vary between light, deep, and REM sleep.
To track your sleep with a Fitbit, you need to set up the app and wear the device to sleep. Ensure that the Fitbit is snugly fastened around your wrist, enabling the sensors to make good contact with your skin. The device cannot track sleep if worn on a pendant or clip. Once you have been still for about an hour, it will begin tracking. You can also track naps that are at least an hour long, and they won't overwrite your nightly sleep logs.
After syncing your Fitbit with the mobile app, you can review your sleep data, including your sleep score, sleep schedule, and sleep stages. The sleep score reflects the quality of your sleep based on your heart rate, the time spent asleep or restless, and your sleep stages. The Fitbit app provides a detailed breakdown of your sleep, including a graph showing your sleep score for the last seven days, the time spent asleep versus awake, and your heart rate and restlessness throughout the night.
Fitbit Premium subscribers get access to more data and personalized insights about their sleep. This includes detailed information about the sounds made during sleep, such as snoring, and a more comprehensive breakdown of their sleep score. Fitbit Premium also offers recommendations to improve sleep and encourages building a sleep routine.

Fitbit devices use a combination of movement and heart-rate monitoring to track sleep
Fitbit devices are well-known for their ability to track sleep patterns and quality. They do this by using a combination of movement and heart-rate monitoring. This allows the device to track your sleep stages, such as light, deep, and REM sleep. By tracking your sleep, Fitbit devices can provide you with insights into your sleep quality and help you understand your sleeping habits.
To track your sleep with a Fitbit device, you need to set up the app and wear the device while you sleep. It is important to ensure that the Fitbit is securely fastened around your wrist, as improper placement can affect the tracking. The device's sensors need to be in good contact with your skin, and the battery should be fully charged. Once you have been still for about an hour, the Fitbit will start tracking your sleep automatically.
The Fitbit device uses heart rate monitoring to measure your breathing and determine when you fall asleep, when you enter different sleep stages, and when you are restless. This information is then used to calculate a sleep score, which reflects the quality of your sleep. The sleep score takes into account factors such as your heart rate, the time you spent asleep or restless, and your sleep stages.
In addition to the sleep score, Fitbit also provides a sleep profile, which is a detailed breakdown of your sleep patterns. The sleep profile includes 10 monthly metrics and a sleep animal characterizing your long-term sleep behaviors. To be eligible for the sleep profile, you must have a Fitbit Premium subscription and use a compatible device. The compatible devices include the Charge 5, Charge 6, Inspire 2, Inspire 3, Luxe, Pixel Watch series, Sense, Sense 2, Versa 2, Versa 3, and Versa 4.
By tracking your sleep with a Fitbit device, you can gain insights into your sleep patterns and quality. This information can help you make informed decisions about your sleep habits and improve your overall sleep quality. Additionally, if you notice any significant changes in your sleep patterns, it may be worthwhile to discuss them with your doctor.

Fitbit's sleep monitoring is designed to help users assess if they're getting a healthy amount of sleep
Fitbit's sleep monitoring feature is designed to help users assess if they are getting a healthy amount of sleep. It does this by tracking sleep patterns and quality, including the time spent in each sleep stage (light, deep, and REM). This information can help users understand their sleep habits and make changes to improve their sleep.
The Fitbit device automatically detects sleep when it has been still for about an hour. It tracks movement and heart rate patterns to estimate sleep stages. While the user is sleeping, the device tracks beat-to-beat changes in heart rate, known as heart rate variability (HRV). These numbers fluctuate as the user transitions between different sleep stages.
In addition to tracking sleep stages, Fitbit also provides a sleep score, which rates the quality of sleep based on heart rate, time spent asleep or restless, and sleep stages. This score is given out of 100 and can be viewed on the Fitbit app or device each morning. Fitbit Premium subscribers have access to more data, including detailed information about the sounds they make at night.
Fitbit also offers guided programs developed with sleep experts, which can help users build better daytime and nighttime habits to achieve deeper sleep. These programs include "Habits for Restful Sleep" and "Get More Sleep," which provide goals, relaxation tools, and personalized guidance to improve sleep.
Overall, by providing insights into sleep patterns and quality, Fitbit's sleep monitoring feature can help users assess if they are getting enough sleep and make informed changes to improve their sleep hygiene and overall health.
