i once bought a Suunto watch came with the heart rate bell, whole package got returned before long, maybe i'm overly-picky but my body just won't feel right with a bell straining the chest.. how did Yan overcome it?
there's app on iphone: "heart rate", works marvelously like this: place ur index finger tip on the camera lens, while measuring, the flash will be on so you can see the blood flow more clearly, the camera will detect it and record your heart rate.
interested in turning it to a small device? so we can get rid of all those big dummy gadget and run more freely ; ) |
