I try to comply with recommendations of my doctor, as I have a very bad health. So, in my opinion, the best way to control yourself is to use activity trackers or have smart watches with this functions. Nevertheless, I have no smart watches, but I tried to find any service which would provide me with such a function as activity tracker. I believed that if I found it everything would be okay. Of course, it was like that, I found this service and they provided me with activity tracking and now I thoroughly continue to watch for my health and various rates, like heart rate for example.
