How Does Fitbit’s Hypertension Detection Work for Pixel Watch Owners?

Fitbit is working on hypertension and ‘unusual trend’ detection for Pixel Watch owners through a new Hypertension Lab study. Participants wear a Pixel Watch 3 for 180 days and receive an Ambulatory Blood Pressure Monitoring cuff to capture data and compare real-world readings. The goal is to detect early signs of high blood pressure using daily smartwatch tracking, similar to Apple Watch safety features.

What Is Fitbit’s ‘Unusual Trend’ Detection Feature?

Fitbit is working on hypertension and unusual trend detection to identify unexpected changes in your health metrics. When the Pixel Watch detects irregular patterns—like rapid heart rate or significant shifts in sleep—it sends alerts so you can take action sooner. This could help users spot changes before symptoms appear, improving prevention and wellness support.

Who Can Join the Pixel Watch Hypertension Study?

Fitbit is working on hypertension and unusual trend detection exclusively for Pixel Watch 3 owners in the US during the testing phase. Users must wear their device as normal for six months. Fitbit Labs selects participants to share feedback that helps improve accuracy and prepare for a wider public release in the coming year.

Why Is Fitbit Adding Hypertension and Trend Detection?

Fitbit is working on hypertension and unusual trend detection to offer preventative health tools and join growing smartwatch medical innovation. As AI-powered Fitbit coaching expands, the company is focusing on early detection of chronic conditions through passive monitoring—giving Pixel Watch users more actionable insights and wellness protection.
