The most interesting launches at the MWC in Barcelona this year have clearly been from Samsung. They launched the much-awaited Samsung S5 with finger print features. Alongside, they also launched their second smartwatch, the Samsung Galaxy Gear 2 and a fitness band called Gear Fit.

Samsung Gear 2 Uses Tizen OSSamsung took the leading in wearable technology with the Samsung Smartwatch that was launched in 2013. However, now that things are in the running, it seems Samsung has made some significant changes to its maiden smartwatch. While the Galaxy Gear worked on Google’s Android OS, the latest Gear 2 OS is Tizen. It’s being said that the primary reason for the shift in OS is to enhance battery life.

The Gear 2 comes in two models—Gear 2 and Gear 2 Neo and runs Tizen OS that was developed by Samsung with various partners. The new Samsung smartwatch comes in three interesting colors–black, orange and brown. Provided with a 1.63-inch screen and a 2.0 MP camera for high definition videos, this one would generate a pool of followers.

What makes the Gear 2 even more loaded are its heath-related features. It comes with a heart rate sensor and pedometer that are being used by many recent fitness apps. The little gadget also has an audio feature, which can be used with a Bluetooth headphone. You could also use the smartwatch as a remote control for your TV or alarm systems. It’ll also give you an alert every time you receive text messages or emails.

Interestingly, the Gear Fit fitness band uses neither of the two operating systems. Instead, it runs on real time OS to maintain a battery life of 3-4 days.
