The Kiwi Wearable device puts smartwatch functionality into a clip-on device that attaches to your existing watch.

The desk now integrates with Fitbit wearables to help you track the time you spend standing and calories burned.

Before you get too excited about these new goodies, know that we may never see them here in the U.S.

Forbes said the wristband will continuously measure heart rate 24 hours a day, and run on a two-day battery.

Garmin is one seriously trusted name among data-loving athletes, and its Forerunner 15 is the best hybrid sports watch-activity tracker we've tested. The price is right, too.

The prototype device can measure key vital signs with an arsenal of sensors.

Fitbit owned nearly half of the basic band market, while Pebble raced ahead among smartwatches/smart bands.

The Lifeband Touch and Heart Rate Monitor Earphones will set you back $150 and $180, respectively.

Embedded health sensors measure activity, stress, and fitness levels—and display it on your iPhone.

Bridging the gap between fitness trackers and GPS-enabled runner's watches, Garmin is adding a new product to the Forerunner family, targeting runners who also want to keep tabs on their daily total activity.

You could say that every adult in the U.S. could use a wearable health monitor, but that is unrealistic.

Nike is abandoning its FuelBand fitness tracker as a hardware product but will continue to develop software for wearables, CEO Mark Parker said Friday.

Western-based crowdfunding sites like Kickstarter and Indiegogo now have company in the race to bring great ideas to market.

Nike will reportedly shift its focus from FuelBand hardware to the software in a bid to compete in the wearables space.

The latest addition to Garmin's fitness product lineup works like a GPS for your car, but for your bike.

The gorgeous Samsung Gear Fit is part fitness tracker and part smartwatch, but it's mainly an accessory for recent Samsung devices; if you want either an activity tracker or a smartwatch specifically, you can do better.

Though it costs twice as much as some competitors, the Basis Carbon Steel Edition is by far the most interesting activity tracker on the market, delivering a wealth of information others can't match.

A limited number of high-end wristwatch fitness trackers, which also function as a runner's watch and heart rate monitor, are available to order for $349.
