Study from Stanford shows wearables aren't accurate counting calories

25 May 2017
On the other hand, heart rate accuracy across devices performed better than expected.

Sort by:

Never surprised me, how can you know how many calories you burn just entering BMI and height? It is obvious it will not be accurate calculations

    Just as many things else. Isn't that obvious?

    The coolest feature of smartwatches to me, is the dumb fact that they can change watchfaces. And, for instance, it is pleasant to me, spending my time making watchfaces that make my Gear S3 look a mechanical watch on AOD. I simply like it because I find it cool. The same way I like to spend my free time with the games I like.

      The reason I never bought or relied on a gadget to measure my calories is that I had this Q in my mind always: How can they be precise? I always doubted them because I know that it's very variable thing to measure. Apparently it's true

          So what if they're not accurate? The point is you wanna buy one the expensive wearables so you don't have enough money left to buy food. Screw calories :D :P

            You don't need to pay that much money for a wearable, simply eat less and exercise more,do you really need to have one of these to get or stay fit?

                        What a surprise. Apple is most reliable and consistent while Android Wear aren't even calibrated.

                          We all knew. I justed wanted to see the error margin. I am happy to see 5% margin for heartbeat but for calories 27% error, for now, this is best :|
                          Will to be waiting for couple of years :)

When I do running, the most thing I used the wearable was to, track time, distance, and speed. Alone, those data won't be useful. But combined data for a week can create a graph to analyze my running performance.

                                      GSM Arena didn't write interesting part that Apple Watch HR readings was much better then Gear S2 which was the most inaccurate. Nothing new for "Samsung Arena" site. They always prefer favorite Samsung. Just not objective.
                                      Here is whole story:

                                      "Across all of the modes of activity, the Apple Watch had the lowest median heart rate error at 2 percent (1.2% to 2.8%), while the Samsung Gear S2 had the highest error rate at 6.8 percent (4.6% to 9%). The Apple Watch was also notably more accurate at measuring heart rate during the walking test than competing products.
                                      For the walking task, three of the devices achieved a median error rate below 5%: the Apple Watch, 2.5% (1.1%-3.9%); the PulseOn, 4.9% (1.4%-8.6%); and the Microsoft Band, 5.6% (4.9%-6.3%). The remaining four devices had median error between 6.5% and 8.8%."

                                        Neither are mobiles. So what is their point? Doing it the old way, will always be more accurate.
