A wrist-worn device that can detect some combination of walking steps, running distance, heart rate, sleep patterns and swimming laps. Fitness bands interact via Bluetooth with an app in a mobile device that configures the device and downloads the wearer's activity data. Most smartwatches support some number of physical actions via a health app; however, dedicated trackers tend to monitor more functions. See smartwatch. |
