![]() ![]() The results show that these devices can be relied upon to accurately track the number of steps you take. In contrast, smartwatches rely on algorithms that process data from accelerometers and gyroscopes to count steps.Īlthough smartwatches generally provide reasonably accurate step counts, they can be influenced by factors like walking speed, arm movement, and other activities that may cause false step readings.Ī study published in the Journal of the American Medical Association measured the accuracy of pedometers in wearable devices and smartphone applications. ![]() They measure steps using a simple mechanical or electronic mechanism that detects movement when you walk or run. When it comes to counting steps, pedometers are the classic choice. This can lead to discrepancies in health metrics, especially for people who fall outside the "average" range. People have different body types, fitness levels, and health conditions, which can influence how their bodies respond to exercise and other activities.īecause most wearables are designed based on general population data, they may not always account for these individual differences. Differences in Individual PhysiologyĪnother factor to consider is the variation in individual physiology. These algorithms are often kept under wraps, making it difficult to evaluate their accuracy and compare them to one another. Each brand, whether it's Apple with its focus on wellness, Samsung with its BioActive sensor, Fitbit with its various models, or any other, has its own algorithms that process raw data from sensors to provide you with your health metrics. One of the main factors affecting the accuracy of health trackers lies in the algorithms and proprietary tracking methods used by various companies. Algorithms and Proprietary Tracking Methods One consideration should be how accurately these devices do what they claim to do. There are several pros and cons to buying a fitness tracker.
