Fitbit is one of the innovative smartwatch brands that can track physical fitness and several more activities that other smartwatches can’t.  

Most Fitbit users are curious to know whether Fitbit is capable of detecting sleep apnea or not. We will explain whether it can track or not, if yes, what specific models can do that, and how you to do that using the Fitbit smartwatch.

Can Fitbit track your sleep apnea?

Of course, your Fitbit smartwatch can track your sleep apnea with its technology. We have also confirmed that the Fitbit smartwatch could track your oxygen level throughout the night, disease conditions like allergies, and concerns regarding breath. Also, we observed that the Fitbit smartwatch is recommended to see a specialist when an individual is to have a proper sleep. 

As we could confirm, the following capabilities are within reach of a Fitbit smartwatch capabilities

  • Heart rate tracking
  • Exercise
  • Food and water consumption
  • Weight
  • Menstrual health
  • oxygen saturation (SpO2) in the sleep
  • Sleep Apnea

What is sleep apnea?

Sleep apnea is a condition that suddenly stops your breathing and starts while you are asleep. Although it doesn’t happen for long, there can be severe health affects you may face. 

Why should I bother about Sleep Apnea?

Sleep apnea is a condition that can drive you into severe disease conditions related to your heart. After searching the internet and asking physicians, we discovered that the results might be coronary artery disease, heart attacks, heart failure, and strokes. 

Furthermore, you risk tuning up your abnormal heart rhythms (arrhythmias) that you brought from birth. 

Note: The most common reason to get these kinds of severe heart problems led by Sleep apnea is the failure of the individuals to detect the condition. 

How You Can Identify This Condition

  • You may find out about this condition simply by detecting the following symptoms. 
  • Your loud snoring person detecting your sudden stopping and the starting of your breathing
  • Gasping air into thin air during the sleep
  • Having a dry mouth when you wake up
  • Headache after a long sleep
  • Detecting by a Fitbit smartwatch

Note: We could find out that a Fitbit smartwatch cannot track the blood pressure of individuals. If you are purchasing a Fitbit smartwatch for this purpose only, we don’tdon’t recommend you this product. 

Also, if you have a severe sleep apnea condition or high blood pressure, we recommend you see a doctor immediately. 

How to detect sleep apnea using a Fitbit smartwatch?

If you have a slight feeling about sleep apnea, that will be confirmed by a Fitbit smartwatch. The following guide will help you to do that properly. 

What do I need?

You need a Fitbit smartwatch that has been updated to the latest version. Although you have a SpO2 sensor as hardware, the software update is essential for the process. You must set up Version 1.88.11 from the relevant App store for that. 

Note: Fitbit Charge 3 had an SPO2 sensor in 2021, but the software did not support the hardware. Therefore, users could not track the quality of their sleep. 


  • You must wear your watch in your hand before going to bed. When you fall asleep, your watch will start to remember your sleep data. 
  • After waking up, you must sync your Fitbit smartwatch with the smartphone or the device you expect to see sleep data.
  • See sleep log data on your smartwatch.

You can see sleep data using your smartphone, Windows 10, and the Fitbit smartwatch. 

Windows 10

You must open the Fitbit app on the dashboard and then tap on the sleep title. Then you must tap on the relevant date to see the sleep log data. 


You must open the Fitbit smart app and then go to the Today tab. Then you must choose the sleep tile. 

Note: If you want to see the sleep log data of the previous day, you must tap o the relevant date. 

Fitbit smartwatch

You must swipe up the smartwatch’s face to get the Fitbit today interface. Then you must check the sleep tile to get sleep information. 

Note: We saw that some users had complained about not having a sleep tile on the watch face. You may enable the sleep tile by going to Settings at the bottom of Fitbit Today. 

  • Observe the sleep patterns

You will be able to see the sleep you have had over the last week now. You will see that there is a High and low line of sleep. If you have a fluctuating line at some points that crosses the high limit, that is an event related to Sleep apnea. 

Note: According to your set preferences, you will also see that as a red line. 

We found this guide from the Official Fitbit website that can help you to track your sleep using your Fitbit smartwatches and bands. 

What Fitbit models support sleep apnea detection?

You will be able to detect sleep apnea using any Fitbit device with an SPO2 sensor. But you must have updated the device to the latest version. Also, you will have to check for that manually. 

Only Fitbit Versa 3 smartwatch can detect snoring and alert you about sleep apnea conditions as notifications. 


We have explained what sleep apnea is and how crucial it is to check the particular condition using a smart device such as a Fitbit smartwatch. If you feel something strange regarding your sleep, you must visit a doctor ASAP.
