These devices are designed to track an individual’s health and fitness information, such as heartrate, sleep patterns, and walking steps. In order to record this information, they contain accelerometers, gyroscopes, and GPS technologies, and are able to store up to 7 days of minute-by-minute data, or daily totals for up to 30 days (in the case of Fitbit). These devices can transfer the information wirelessly (via Bluetooth or wifi), to smartphone applications, or to one’s home computer.
