Close on the heels of Microsoft Band and Fitbit Surge comes yet another fitness tracker that packs in quite a punch. Meet Jawbone's UP3.

The UP3 is the successor to the UP24 fitness tracker from Jawbone and, like most next-gen iterations, is an improvement on its predecessor. The UP3 sports a cooler design and several new features compared to the UP24.

The new fitness tracker is not only sleeker but also smaller than the UP24. It weighs only 29 gms and measures 20mm x 12.2mm x 3.0mm-9.3mm.

The UP3 is also capable of wireless syncing and has a multi-sensor platform that includes bioimpedance and skin and ambient temperature sensors, which indicate if a user is tired, dehydrated, or stressed.

The UP3 is also water-resistant up to 10 meters, and the auto activity classification feature logs a user's fitness activities. There is also a Smart Alarm and built-in tri-axis accelerometer to count steps. The UP3 also measures the calories burned by the user.

Like the Microsoft Band, the UP3 also has a galvanic skin response sensor.

"Our mission was to create the world's most powerful activity tracker in the smallest possible design, and we believe we have done that with the UP3 band" shared Travis Bogard, VP of product management and strategy at Jawbone. "Our advanced, multi-sensor platform delivers a huge amount of new health data, backed by our smart algorithms and our highly personalized Smart Coach system. And because the technology is fully updateable, we're able to unveil great new features and experiences in the coming months."

The activity features on the UP3 are also capable of differentiating between exercises so that the calories burned can be assessed better. The device can also keep track of your sleep patterns: REM, deep or light sleep.

In terms of design, the fitness tracker is like a band with a watch-type clasp that can be adjusted.

While the UP3 does not have a display like other fitness trackers or smartwatches, users have the option of tapping on top of the tracker to see the lights, which reflect if a user is nearing his/her daily goal.

The three LEDs are single-colored: blue indicates sleep; orange is for activity; white denotes notifications. The device's band is made of anodized aluminum and packs in a 38 mAh rechargeable battery that charges in 100 minutes. The battery support offered on a single charge is up to seven days.

The UP3 will initially be available in Black Twist for $179.99. Jawbone will introduce two more colors -- red and silver -- in 2015.
