An activity tracker is a device or application for monitoring and tracking
fitness-related metrics such as distance walked or run, calorie consumption, and in some cases heartbeat and quality of sleep. The term is now primarily used for dedicated electronic monitoring devices that are synced, in many cases wirelessly, to a computer or smartphone for long-term data tracking, an example of wearable technology. There are also independent smartphone apps and Facebook apps.
The term "activity trackers" now primarily refers to wearable devices that monitor and record a person's fitness activity. The concept grew out of written logs that led to spreadsheet-style computer logs in which entries were made manually, such as that provided in the US by the President's Council on Physical Fitness and Sports as part of The President's Challenge. Improvements in technology in the late 20th and early 21st century allow automating the monitoring and recording of fitness activities and integrating them into more easily worn equipment. Early examples include wristwatch-sized bicycle computers that monitored speed, duration, distance, etc., available at least by the early 1990s. Wearable heart rate monitors for athletes were available in 1981. Wearable fitness tracking devices, including wireless heart rate monitoring that integrated with commercial-grade fitness equipment found in gyms, were available in consumer-grade electronics by at least the early 2000s. Wearable fitness tracking computers with tightly integrated fitness training and planning software were available as consumer products by at least 2006.
Wearable sensors have been widely used in medical sciences, sports and security. Wearable sensors can detect abnormal and unforeseen situations, and monitor physiological parameters and symptoms through these trackers. This technology has transformed healthcare by allowing continuous monitoring of patients without hospitalization. Medical monitoring of patients’ body temperature, heart rate, brain activity, muscle motion and other critical data can be delivered through these trackers. Moreover, in sports training there is an increasing demand for wearable sensors. For example, measurement of sweat rate was possible only in laboratory based systems a few years ago, but is now possible using wearable sensors.
Activity trackers are available both with and without display
Certain movements of the user, such as working in the household, cycling, swimming, dancing or rowing can distort the results obtained from activity trackers. In a test of Stiftung Warentest, for example, no product determined even approximately the distance of a bike ride. Furthermore, the determined values for the human energy transformation are erroneous. With the heart rate large deviations have been observed at wristlet trackers, and it is recommended for this purpose to use appropriate chest straps.
Wristbands can be uncomfortable to wear and inadvertently being lost. For some products genotoxic substances were detected.
The connection of activity trackers with social networks can lead to violation of privacy, such as involuntary publication of sexual activity The apps of some activity trackers not only transmit personal data, but also private address lists to servers on the Internet without notifying or asking the user.
