(Fitbit) ![Author Photo](https://images.hindustantimes.com/tech/static/revamp/images/png/HTTech-new-circle-logo.png) ### By HT TECH Fitbit has launched a new watch face that makes it easier for users to track their blood oxygen saturation (SpO2) levels. The SpO2 Signature clock face will be available for Fitbit Ionic, Versa and Sense devices. Fitbit plans to launch more SpO2 watch faces soon. Fitbit hasn’t revealed when exactly the SpO2 watch face will be available but it did say that the new watch face won’t be available in all markets. Fitbit also warns that this feature is not to be used to “diagnose or treat any medical condition”. Keeping a check on SpO2 levels has become very important due to the pandemic. Fitness bands have also made it a point to have an SpO2 sensor these days. “By using Fitbit sensors to measure the relative reflection of red and infrared light from your blood via your wrist, and seeing how it varies as your heart beats, we can estimate your SpO2 value,” Fitbit explained in a blog post.

The Fitbit SpO2 Signature watch face is free for Fitbit users and it displays the percentage level on the display. It also shows the range of the SpO2 level. Once enabled, it will track the user’s SpO2 levels while they’re sleeping. Within an hour of waking up, the SpO2 level and range will be updated on the watch face. Fitbit premium users can also check their trends in the upcoming Health Metrics dashboard.
