But they are pretty reliable in counting steps and tracking heart rate.

        Calories are a measure of heat, so it's useless in anything because we don't "burn" things. What we do with fat is to rebuild cells that were demaged by growth (muscles/bones/hair/nails) or by their cycle (skin etc). Less or more calories doesn't equal nutrients. Nutrients in a food doesn't mean they all will be digested or they are digestible.
        For example iron: in meat we got sufficient and is the most digestible for us, compared to the one in spinach.

          How could anybody possibly expect smartwatches to be capable of tracking energy expenditure? It is pretty much impossible to do on your wrist, no matter what equipment you use.

            Any phone app at google play can do a lot more things better.
            Cant say same about IOS becuase IOS have maybe 20% of apps of google play and usualy the worse ones.

              I have seen some people who had serious problems with low caloric intake and high output, which lead to malnutrition. Not really good thing.

                Since when someone who really wants to do some sport needs a watch to count calories? This is an absolute con, just go out and run anywhere or at the gym without any gimmick at the hand. One shirt, one short and a pair of good shoes are more than enough. And if you really want a watch go for the dedicated ones, like Garmin, which is great for sports.

                  One good thing about smartwatches is receiving notifications when your phone is on mute.
                  So you don't have to buy an expensive one.

                      "People who use smart wearables tend to increase overall activity and steps count"

                      Am a good example

                        No smartwatch is a medical-grade equipment, most of the ones I've seen literally say on the box or in a manual that you should use it as a "rough estimation" or "approximation" and not as a firm statement of your condition.
