Fitbit trackers boasting the company's PurePulse heart rate monitoring technology are "dangerous" and pose a risk to general consumers. That's according to Dr. Edward Jo, assistant professor of Applied Physiology at California State Polytechnic University. "It can definitely put them at risk."
The Fitbit Charge HR was accurate 84 percent of the time, and the Basis Peak was accurate 83 percent of the time. The researchers found that the harder someone exercised, the less accurate the trackers were. Fitness trackers usually measure heart rate using sensors that detect the pulse through the skin on your wrist.
Your heart rate changes from minute to minute. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed. Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute.
For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the person's physical condition and age. For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm, according to the AHA.
If your Fitbit's heart rate monitor shows 0, it's likely that the heart rate monitoring feature is off. Open your device's settings app and change your heart rate setting to either Auto or On. If it already shows Auto or On, tap it off, wait 30 seconds, and tap it back on. That usually solves this problem!
The Fitbit Inspire doesn't have a heart rate sensor, which is a huge omission at that price. Unlike some other devices at this price point, the Fitbit duo lack in-built GPS, which makes them a lot less useful for those who don't want to carry their phones with them while exercising.

Can Fitbit measure/monitor blood pressure? Like I have mentioned, the answer is no, there is no Fitbit device that can track or monitor blood pressure.
The Fitbit PPG-based heart rhythm tool is designed to identify irregular rhythm episodes with no symptoms that might otherwise go undetected, and the Fitbit ECG feature is designed to support those who want to screen themselves for possible AFib and record an ECG trace they can review with their doctor.

All Fitbit trackers and watches are water-resistant, which means they're rain-proof and splash-proof and can stand up to even the sweatiest workout. You can swim or shower with certain Fitbit devices. For more information about wearing your Fitbit device, see our Wear and Care page.
There's just a lot more to the Versa. It is a smartwatch, whereas the Blaze is a “smart fitness watch.” Both have connected GPS (neither have built-in GPS—you'll have to go to the Ionic for that), smartphone notifications, and music control, but the Versa also features: Water resistance to 50 meters.
The new Fitbit Blaze is a good Fitbit. Like earlier Fitbit models, the $200 Blaze will track your daily activity, count your steps, monitor your heart rate, gauge how well you're sleeping, and put all of that data into an excellent, easy-to-use app on your phone.
Your used Fitbit is worth anywhere from $15 to $65.
