Fitness trackers are a more sophisticated version of the pedometer; in addition to counting steps, they contain additional sensors such as accelerometers and altimeters to collect or estimate measures including the speed and distance travelled, heart rate, calorie expenditure, or the duration and quality of sleep.

A digital Omron HJ-112 pedometer Mechanical pedometer. A pedometer, or step-counter, is a device, usually portable and electronic or electromechanical, that counts each step a person takes by detecting the motion of the person's hands or hips.
An accelerometer measures proper acceleration, which is the acceleration it experiences relative to freefall and is the acceleration felt by people and objects. [2] Put another way, at any point in spacetime the equivalence principle guarantees the existence of a local inertial frame, and an accelerometer measures the acceleration relative to that frame. [4]
McKenzie and his team argue the primary advantages of systematic observation over other methods of assessing physical activity (e.g., self-reports, accelerometers, pedometers, heart rate monitoring, doubly labeled water) are that it is a direct method and it allows for the simultaneous generation of information on both the physical environment ...
Fitbit is a line of wireless-enabled wearable technology, physical fitness monitors and activity trackers such as smartwatches, pedometers and monitors for heart rate, quality of sleep, and stairs climbed as well as related software. It operated as an American consumer electronics and fitness company from 2007 to 2021.
Accelerometer — an accelerometer can measure any motion that is used in combination with the other mentioned components, providing motion and location sensing heart rate data via an algorithm 4. Algorithms — an algorithm is formed from the processor and the accelerometer into biometric data .
Routh writes that he has been reading about the life of founding father Hamilton and “crying” over his death in a duel with former Vice President Aaron Burr.
Foot pod attached to a running shoe. An inertial footpod is a device used to track running measurements such as speed, distance travelled, pace, etc., which would generally only be available on treadmills or with a GPS unit.
