Suffering from hypertension? You might be wondering, can your Fitbit watch measure blood pressure? Fitbit is famous for its accurate heart rate and activity tracking, but when it comes to blood pressure, the story is a little different.
Fitbit has filed patents and conducted internal research using Pulse Arrival Time (PAT) technology. However, currently, no Fitbit device available in the market measures blood pressure.
Does Fitbit Watch Measure Blood Pressure?
No, your Fitbit Watch cannot measure blood pressure as of Nov 2025.
Google’s Fitbit device is widely recognized for its accurate health and fitness measurements, like heart rate, sleep insights, and physical activity. However, when it comes to your well-being, measurement of blood pressure is not something that can help you check.
Rushing for a blood pressure cuff is not always convenient, especially when you are traveling on the road or at the office. Hence, many smartwatch developers devoted themselves to finding a solution, like measuring blood pressure using smartwatches.
However, it is a challenge because the relationship between Pulse Arrival Time (PAT) technology and actual blood pressure is considered weak and inconsistent. It is still not as accurate as traditional cuff measurements or FDA-approved devices.
Fitbit’s new patent: smarter blood pressure monitoring?
- According to a patent filed by Fitbit in March 2025, they plan to measure blood pressure from a finger-worn device and not a traditional cuff.
- Fitbit is exploring the use of PPG sensors combined with a mechanical or inflatable pressure element to mimic a cuff in order to get a blood pressure reading.
- The patent also reveals that Fitbit might combine readings from multiple sensors (optical and mechanical) to improve accuracy.
Fitbit Watch Measure Blood Pressure: Accuracy And Limitations
The Fitbit patent looks promising in order to have quick, on-the-go readings of your blood pressure; however, you should have a fair knowledge of its potential accuracy and limitations .
Accuracy
PAT-based readings that will potentially be used to predict the blood pressure of the user are not reliable and should not be considered a replacement for medical-grade devices.
If the patent becomes a reality, the accuracy might be improved, but calibration with a cuff will likely still be required.
Limitations
Fitbit does not have FDA clearance for any of its blood pressure features that are currently being tested. So, you cannot consider Fitbit as a replacement for professional blood pressure monitoring gadgets.
PAT and optical methods will provide estimates, and the new patent reveals future potential, not a currently available product.
Competitors With Blood Pressure Monitoring
Samsung is a strong competitor in the smart wearable market, implementing blood pressure measurement features in their Galaxy 4, 5, and 6 smartwatches with calibration using a cuff.
Omron HeartGuide is another FDA-cleared smartwatch designed specially for blood pressure monitoring.
Amazfit and Huawei smartwatches also provide basic blood pressure readings, although not FDA-approved.
Conclusion
If you are wearing a Fitbit on your wrist right now, you have the opportunity to check multiple fitness and health parameters, but not your blood pressure, yet.
While the patents filed by Fitbit look promising, we don’t know when and if they will hit the market. Till then, competitors like the Samsung Galaxy Watches, Amazfit or Omron HeartGuide seem like a good alternative. Even Google seems to be working on high blood pressure screening on the Pixel Watch.
