When Apple launched its first smartwatch in 2015, there was a sense that the company didn’t exactly know what the device was for. But within a few years, it carved out an identity focusing mainly on health and fitness, with millions of owners using their Apple Watches to track metrics such as steps taken, minutes of exercise each day, and how often they stand. Nearly every other smartwatch soon followed Apple’s lead, and they all promise to help you get fit and stay healthy.
