You’ve seen the ads or maybe a stray TikTok claiming your wrist is basically a mini-doctor’s office now. It’s a tempting thought. Imagine just glancing at your watch and knowing if your heart is screaming or chilling out. But if you’re looking for a Fitbit that does blood pressure in the way a traditional cuff does, we need to have a real talk.
Honestly, the "is it there or is it not?" game with Fitbit and blood pressure is a bit of a mess.
Here is the flat-out truth: As of 2026, there is no Fitbit you can buy at Target or on Amazon that has a built-in, inflatable cuff or a medical-grade sensor that gives you a systolic and diastolic reading with one tap.
It's frustrating. You want that data. I get it. But while Samsung and even some niche brands like Omron have dipped their toes in, Google (which owns Fitbit now) has been moving a lot slower, mostly because the FDA is, well, very strict about this stuff.
The Fitbit Blood Pressure Study: What’s Actually Happening?
If you feel like you heard Fitbit was doing this, you aren't crazy. They’ve been "testing" it for years. Back in 2021, they launched a massive study using the Fitbit Sense to see if they could track something called Pulse Arrival Time (PAT).

Basically, PAT is the time it takes for a pulse of blood to reach your wrist after your heart beats. The theory is that if your blood pressure is high, that pulse travels faster. It’s clever. It’s non-invasive. But it's also incredibly hard to calibrate.
Right now, in early 2026, the action has shifted to Fitbit Labs. If you have a Pixel Watch 3 or certain newer Fitbit-integrated devices, you might have seen an invite to the "Hypertension Study Lab."
- The Goal: Google is trying to use AI to spot "unusual trends" rather than giving you a raw number.
- The Catch: They are literally sending participants 10,000 actual medical-grade blood pressure cuffs to "verify" the watch data.
- The Limit: It's mostly restricted to the US and requires a lot of manual logging.
Why Can't My Charge 6 Just Do It?
The hardware is the wall.
Standard blood pressure measurement requires occluding—aka stopping—the blood flow. That’s why the cuff at the pharmacy squeezes your arm until it hurts. A Fitbit is just a light (PPG sensor) hitting your skin. While that light is great for heart rate, it doesn't "feel" the pressure of the blood against the artery walls.

There are rumors about a new sensor patent involving a force-sensitive touch display. The idea is you’d press your finger against the screen, and the watch would measure how much force you’re applying while the PPG sensor reads your pulse. It’s a digital version of the "cuff squeeze." But for now? It’s just paperwork in a patent office.
What You Can Actually Do Right Now
Since a Fitbit that does blood pressure natively doesn't exist yet, you have to play the integration game. It's not as cool as a "magic watch," but it’s the only way to get accurate data into your app.
- Buy a Bluetooth Cuff: Brands like Omron or Withings make cuffs that sync directly.
- Use Health Connect: On Android, you can bridge the data. Your cuff sends the BP to Google Fit or Health Connect, and Fitbit should (in theory, depending on your version) show that data in your health metrics dashboard.
- Manual Logging: It sucks, but you can still type your readings into the "Health Metrics" section of the Fitbit app.
Watch Out for the "Fake" Apps
If you go to the App Store and see something promising to measure blood pressure using just your phone's camera or your old Fitbit Versa 2, delete it. The FDA issued a pretty stern warning in late 2025 about unauthorized BP apps. They aren't just inaccurate; they’re dangerous if you’re using them to manage actual hypertension medication.
The 2026 Landscape
The competition is heating up. Apple finally rolled out hypertension alerts (not raw BP numbers, but "hey, something is wrong" pings) on the Series 11. Samsung’s Galaxy Watch 8 still does BP, but you have to calibrate it with a real cuff every few weeks, which most people forget to do.

Fitbit is clearly aiming for a "passive" system. They want the watch to just tell you, "Hey, your trends look like high blood pressure," while you're sleeping. No squeezing, no calibration. But we aren't there yet for the average consumer.
Your Action Plan for Heart Health
Stop waiting for a software update to fix your blood pressure. If you're genuinely worried about your heart, here is the move:
- Get a validated home monitor: Look for the "BIHS" or "dabl" validated stickers.
- Track your RHR: Your Resting Heart Rate (which Fitbit is great at) is often a "canary in the coal mine." If your RHR starts climbing over a week, your blood pressure is likely following suit.
- Watch your salt and sleep: Fitbit's sleep tracking is still its best feature. Use that. Poor sleep is a massive, often ignored driver of hypertension.
If you really want to be on the cutting edge, open your Fitbit app, go to the "You" tab, and check if you're eligible for the Fitbit Labs experiments. You might get a chance to help them finally build the feature everyone has been asking for since 2015.
Check your Fitbit app for the "Labs" icon today to see if your device supports the current hypertension trial. If it doesn't, stick to a physical cuff for any medical decisions.
