fitness tracker

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.

A Lot of Trackers
In 2015, Under Armour debuted UA Record, an app that pairs with all these brands and imports the data from the user's accounts. UA Record is an evolution of the MapMyFitness platform, which Under Armour acquired in 2013.






smartwatch

A computer-based wristwatch that provides an extension to a smartphone via Bluetooth. Emerging in 2011, by 2015 there were more than 100 models on the market. A major smartphone advantage is handling phone calls and messages without having to extract the phone from pocket or purse, although not every model supports this feature. The Gear S was the first stand-alone smartwatch to have a unique phone number and make calls entirely on its own (see Samsung Gear S).

Smartwatches often include exercise apps for managing health (see fitness tracker) and may have built-in pulse sensors for reading the wearer's heartbeat. After only a few years in the market, fitness turned out to be a major inducement for a smartwatch. Where applicable, mobile apps are enhanced to synchronize with smartwatches.

Apple Watch
In 2015, the introduction of the Apple Watch line made quite a splash as both a fashion statement and a smartwatch with unique features (see Apple Watch).

Early Smartwatches
Throughout the 2000s, a variety of smartwatches emerged that were not synchronized with a smartphone (see Microsoft Smart Watch). See hybrid smartwatch, Samsung Gear, notification fatigue and personal communicator.
