Measure your heart rate without the usually annoying chest strap of conventional heart rate monitors. The MIO Alpha uses two bright LED lights and an electro-optical cell on the back to monitor the rhythmic changes in your blood volume and hence determine your heart rate. It's the most comfortable way to measure your heart and provides a continuous heart rate display. With Bluetooth Smart (4.0) technology you can connect it with your smartphone and sync it with some of the best fitness apps around including MapMyRun, Wahoo, Endomondo, and Runkeeper.
