A pedometer primarily counts steps, which is how it tracks your activity. By knowing your average stride length, you can estimate the distance you’ve walked by multiplying the number of steps by that length. This is why the concept of step-counting, with distance as a derived measure, fits best. It doesn’t directly measure heart rate, weight, or calories burned—the device would need separate sensors or calculations to provide those metrics. So the key idea is that a pedometer’s main function is to count steps, with distance being a common derived value.
