In a recent study conducted by Standford University, the Apple Watch came out as one of the most reliable smart wearables in the market to measure calorie outputs and heart rates of 29 men and 31 women who volunteered for the study.
Researchers directed the volunteers to perform different activities such as walking, running, and cycling, and compared the data using both smart wearables and clinical devices. Initially, the study made use of seven wearbles that are commonly used by the consumers, Apple Watch, Basis Peak, Fitbit Surge, Microsoft Band, Mio Alpha 2, PulseOn and Samsung Gear 2.
In measuring the heart rate, Apple Watch came with a median heart rate error at 2 percent, with Samsung Gear 2 having a 6.8 percent error. Indeed, the result of this study may be a good reason for Apple to gain new buyers, as people now are keeping record of their calories burned and heart rate.
On the other hand, in measuring calories, Apple Watch came in second, with the Fitbit Surge in the first place in accurately measuring calorie output. The Fitbit Surge has a 27 percent error rate, while Apple Watch has 40 percent error rate.
Although these wearables are not accurate at all compared to the clinical devices, the Apple watch clearly stands out from the rest of the tested devices. In measuring calories burned, no device, including Apple is able to provide the exact measurement, however, Apple Watch is able to provide the best result in measuring energy expenditure.
For Apple Watch users, there's nothing to be upset about, as there are many features that you can actually use every day.
