If you've been mourning the demise of Nike's Fuelband and want a bare-bones activity tracker, then Polar's got your back. The fitness company is launching a second-generation Loop that retains much of the look and feel of the original with a sprinkling of new features. The most notable is probably the smart notifications and alarms that we've seen come to the company's other high-end wearables like the V800. The company isn't specific about what you'll be able to do, but we'd imagine vibrating call and text alerts will be included as part of the package. Then, there's the news that the Loop 2 will come with inactivity alerts, and will buzz you Jawbone Up-style, if it thinks you've been sat idle for too long.
