Runware has introduced its Runalyzer Blue chest strap for iPhone 5. This heart rate monitor uses Smart Bluetooth technology and purportedly works with more than 100 applications such as 321Run, iSmoothrun, Endomodo, RunKeeper and Runtastic.

An application like Runtastic provides your heart rate and “locates” you on the ski slopes. Features include heart rate, heart rate zones but also distance, altitude, speed, calories burned and more. Plus, voice sports coaching announcements can even alternate with your favorite music.

The Runalyzer Blue runs for up to 18 months with a single battery on a daily use basis,. It has a suggested retail price of US$74. For more info go to http://tinyurl.com/bd7nxe7 .
