Study finds Apple Watch is most accurate wearable at measuring heart rate

When it comes to measuring heart rate and calories burned, not all fitness trackers are created equal, based on the findings of a scientific study that pitted the top wearables on the market against each other.

The in-depth study conducted by researchers at Stanford University was published today, revealing that Apple Watch is the most accurate wrist-worn tracker on the market, but it’s still far from perfect.

In their paper titled “Accuracy in Wrist-Worn, Sensor-Based Measurements of Heart Rate and Energy Expenditure in a Diverse Cohort,” researchers evaluated the Apple Watch, Basis Peak, Fitbit Surge, Microsoft Band, Mio Alpha 2, PulseOn, and Samsung Gear S2.apple watch chart

Researchers concluded that Apple Watch achieved the lowest overall errors when measuring both heart rate and energy expended. Samsung did the worse overall with the Gear S2 reporting the highest amount of errors for both fields.

The study found that the wrist-worn trackers had the lowest error rate when a person was cycling. Walking provided the highest amount of errors.

Six of the seven devices tested all achieved a median heart rate error below 5%. Tracking calories burned is much tricker though. Not a single device tested had an error rate below 20 percent, so if you’re trying to use your Apple Watch or FitBit to count calories, you probably need to find a more accurate method.

Nice band. Worked well. Need to be sure to watch the video on using the tool to adjust the band.

I contacted the store but they never replayed to me i don't recommend to buy here!

Not only is this iWatch such a practical means of holding my watch while charging, it’s a hoot - looks like my original Mac. I love it.

The case doesn’t totally align but it does it’s job. The part that stinks is that it attracts lint and dust because it’s silicone.

Great tidy solution

You know what happens, all your devices need a charger. 2 iPhones, an Apple Watch, iPad and more. My old solution was fast charger with 4 USB outlets plugged in to an outlet in the kitchen. Worked, but not pretty.

Let me start by saying this charger looks great. I got rid of all the other cables and keep this out in the kitchen. Much tidier! Phones charge quickly. Apple watch does too but you to be careful that it goes on right. Also, I have a metal band on mine so I have to close it before I put it on the stand or else it would rest on the screen of the phone below it.
