This question was asked by Stanford University researchers. And to know it reliably, the experts conducted their own study, which was attended by 60 people of different age, sex, body mass index and 7 of the wearable device: Apple Watch, Basis Peak, Fitbit Surge, Microsoft Band, Mio Alpha 2, PulseOn and Samsung Gear S2. Volunteers wore seven gadgets while walking, Jogging on the treadmill or pedaling on a stationary bike. Throughout the run-time load of the subjects were medical devices that hold evidence.

As it turned out, all trackers activity showed a surprise to the researchers, the accuracy in measuring heart rate. The error was not more than 5%. However, in calculating the calories burnt consumer electronics was not strong. Only the Apple Watch and Fitbit Surge were able to produce a result with a minimum error of 27%. The insights of the other participants to 97% (the worst result from PulseOn) differed from the stated medical devices.

As the scientists, the consumption of calories depends on many variables. Consumers seeking sensible and responsible approach to your body, it should be explicit in the program gadget your age, height, weight. At the same time, the algorithm of calculation of the energy created by the manufacturer of the fitness tracker, and he, unfortunately, is far from ideal mechanism. So do not blindly rely on the conclusions of the consumer electronic device on this parameter, and do not need to eat extra in the hope that additionally passed the “mile” will burn a substantial part of the body of calories.
