Which device is worn around the waist or wrist and tracks step count and distance traveled?

• A. Heart rate monitors
• B. Activity trackers
• C. Accelerometers
• D. Pedometers

Answer: (D)

Counting steps and using them to estimate distance is what a pedometer is built for. This device is worn on the body—commonly at the waist or on the wrist—and it detects each step you take, giving you a step count. From that count, distance is estimated by multiplying steps by your stride length, which you can set or approximate. Heart rate monitors focus on heart rate data rather than steps. Accelerometers are movement sensors that many wearables use to detect activity, but they’re not a standalone step-counter device. Activity trackers can count steps and distance too, but the description most clearly matches a pedometer—specifically designed to count steps and estimate distance while worn on the body.
