In its most recent update (being released throughout February), Fitbit now allows users in the US to track their blood glucose readings directly in the app. However, the Fitbit device itself still does not have the capability to measure blood glucose levels; the new feature only pertains to tracking within the app.
Fitbit mentions in their blog post introducing this feature: “Having a dedicated space to monitor your blood glucose alongside daily health metrics like activity, nutrition, sleep, stress, and other biometrics such as weight can provide valuable insights, helping you discover new strategies for better health management.”
Tracking blood glucose can be beneficial for individuals managing diabetes or certain other health conditions. This feature doesn’t substitute professional medical advice but aims to help users identify patterns linking their glucose levels with meals, physical activity, and sleep.
If you use the OneTouch Reveal app in conjunction with a glucose monitor, Fitbit can now import your readings from that app. Otherwise, you'll need to manually log your glucose data. The app can be set up to remind you, including sending alerts directly to your Fitbit device.

With a Fitbit Premium subscription ($9.99/month), you can track how your glucose levels align with your target range over the past 30 days. Additionally, you can include your glucose data in Wellness Reports to share with your healthcare providers.
Several other updates are being released simultaneously. U.S. users can now track ECG readings on the Fitbit Sense and view SpO2 (blood oxygen) levels directly on the wrist with the Fitbit Charge 4.
The Health Metrics dashboard, which was once exclusive to the Sense and Versa 3, is now accessible on the Versa 2, Inspire 2, and Charge 4. Free users can view 7 days' worth of data, while premium users have access to the full 30-day history.
