No Fitbit currently measures blood pressure. As of 2025, none of the models in the Fitbit lineup, from the Charge 6 to the Sense 2 to the Pixel Watch, include blood pressure monitoring hardware or software. Fitbit has patented technology that could enable this in future devices, but nothing has made it to a consumer product yet.
That said, blood pressure tracking on smartwatches is a fast-moving space, and understanding what exists, what’s coming, and how it all works can help you decide whether to wait or look elsewhere.
Why Fitbit Doesn’t Offer Blood Pressure Yet
Blood pressure is one of the hardest vital signs to measure from the wrist. Unlike heart rate or blood oxygen, which can be read by shining light through the skin and measuring what bounces back, blood pressure traditionally requires restricting blood flow with an inflatable cuff and then measuring the force of blood pushing against artery walls as the cuff deflates. Shrinking that process into a watch is an enormous engineering challenge.
Fitbit devices do have optical heart rate sensors (the green and red lights you see pulsing on the back of the watch). These sensors can detect pulse patterns and blood flow characteristics, but translating those signals into a reliable blood pressure reading requires additional technology and, critically, regulatory clearance. Google, which owns Fitbit, has filed patents related to blood pressure sensing using force detection at the wrist, but patents don’t guarantee a product launch. For now, Fitbit’s sensors track heart rate, heart rhythm (for atrial fibrillation detection), blood oxygen, and skin temperature.
Smartwatches That Do Track Blood Pressure
A few competitors have moved ahead with blood pressure features, though each comes with significant trade-offs.
Samsung Galaxy Watch series: Samsung offers blood pressure monitoring on its Galaxy Watch models through the Samsung Health Monitor app. The catch is that you need a separate upper-arm blood pressure cuff to calibrate the watch every 28 days. Calibration requires taking three cuff readings within a 30-minute window and entering the results into the app. Between calibrations, the watch estimates blood pressure using its optical sensor. This feature is available in some countries but has regulatory limitations in others, including the United States, where it’s not FDA-cleared for blood pressure.
Huawei Watch D2: Huawei took a different approach by building a tiny inflatable cuff directly into the watch band. The Watch D2 uses a near-silent micropump to inflate a narrow cuff (under 27 mm wide) and performs an oscillometric measurement, the same basic method used by a traditional arm cuff. The watch body measures 48 × 38 × 13.2 mm, making it noticeably thicker than a typical smartwatch. This approach is more accurate than optical-only estimation, but the device is not widely available in the U.S.
How Cuffless Blood Pressure Technology Works
The technology most likely to appear in future Fitbits and other mainstream smartwatches is called cuffless blood pressure monitoring. Instead of physically compressing an artery, these systems analyze the pulse wave, the shape and timing of each heartbeat as detected by the watch’s optical sensor. Two key measurements come into play: pulse wave analysis, which looks at the contour of each pulse to infer arterial stiffness, and pulse transit time, which measures how quickly the pressure wave travels from the heart to the wrist.
A recent study using Fitbit hardware explored an AI-based approach that goes further. Instead of relying on hand-designed measurements, researchers trained a deep learning system to analyze 15-second windows of optical pulse data alongside accelerometer signals from the wrist. The accelerometer captures subtle mechanical vibrations from the heart beating (a signal called a ballistocardiogram), and the AI learns complex patterns across both signals that correlate with high blood pressure. This system was designed to flag signs of hypertension rather than give you a specific reading like 120/80.
The distinction matters. Giving a precise blood pressure number from the wrist is far harder than detecting whether someone’s blood pressure is chronically elevated. Fitbit’s research appears focused on the screening angle, identifying people who should get checked with a proper cuff, rather than replacing the cuff entirely.
The FDA Clearance Bottleneck
In the U.S., any device that claims to measure blood pressure needs FDA clearance, and that bar is high. As of mid-2025, the FDA has cleared five cuffless blood pressure devices, four for use in medical settings and one for over-the-counter consumer use. That consumer device, the Hilo Band, is a dedicated blood pressure wristband (not a full smartwatch) expected to hit the market in 2026 at around $280. It automatically checks blood pressure up to 50 times a day.
All five cleared devices still require periodic calibration against a traditional cuff. This is a recurring theme in every cuffless approach: the optical or AI-based estimates drift over time, and a cuff reading anchors them back to reality. Until a device can deliver accurate readings without any calibration, the experience for users will always involve keeping a standard blood pressure monitor around.
What Fitbit Can Tell You About Heart Health Now
While blood pressure isn’t available, current Fitbit models do track several metrics that relate to cardiovascular health. Resting heart rate trends over weeks and months can reveal improvements in fitness or flag periods of stress and illness. Heart rate variability, which measures the tiny fluctuations between heartbeats, reflects how well your nervous system adapts to demands. The ECG feature on the Sense 2 and Pixel Watch can detect atrial fibrillation, an irregular heart rhythm that raises stroke risk.
None of these replace a blood pressure reading, but they provide a broader picture of cardiovascular function. If your primary concern is tracking blood pressure, your best option right now remains a validated home blood pressure monitor with an upper-arm cuff. These cost $30 to $80 and are consistently more accurate than any wrist-worn device on the market.
Should You Wait for a Fitbit With Blood Pressure?
Google has clearly invested in the research. The patent filings and the AI-based hypertension detection study suggest this is an active priority. But there’s no announced timeline, no leaked hardware, and no indication that a blood pressure-capable Fitbit is arriving in the next year. The regulatory path alone takes time even after the technology is ready.
If you need blood pressure tracking now, the Samsung Galaxy Watch (with its calibration requirements) or a dedicated device like the upcoming Hilo Band are the closest options. If you’re willing to carry a slightly bulkier watch, the Huawei Watch D2 offers the most measurement-like experience with its built-in cuff. For everyone else, a standard arm cuff paired with a Fitbit for other health metrics remains the most practical and accurate setup.
