Fitbit Labs Rolls Out ‘Unusual Trend detection’ & Launches Hypertension Study
Fitbit is expanding its Fitbit Labs program with a new “Unusual Trend Detection” feature and simultaneously initiating a study focused on hypertension. The rollout, beginning November 7, 2025, aims to proactively alert users to potential health changes detected through their wearable data, while the hypertension study will investigate the feasibility of early detection using Fitbit devices.
These developments represent Fitbit’s continued push into preventative health monitoring, leveraging the wealth of physiological data collected by its trackers and smartwatches. The new features are designed to empower users and perhaps facilitate earlier intervention for health concerns, a critical step given the prevalence of conditions like hypertension – impacting roughly half of U.S. adults, according to the CDC – and the benefits of timely diagnosis and management.
The ”Unusual Trend detection” feature analyzes a user’s heart rate, activity, and sleep patterns, flagging deviations from their established baseline. Fitbit emphasizes this isn’t a diagnostic tool,but rather a notification prompting users to consider potential factors influencing the change and consult with a healthcare professional if concerned. The feature is currently available to Fitbit Premium subscribers within the Fitbit app.
Alongside this, Fitbit has begun enrolling participants in a research study examining the potential of Fitbit data to identify individuals at risk of developing hypertension. The study will utilize data collected from participants’ devices to assess the accuracy of algorithms in predicting blood pressure changes. Interested users can find more details and enrollment details within the Fitbit app.
