We've seen plenty of fitness watches, armbands and pedometers, but it's a rare moment when we see a pedometer that sits on your forehead. Spree believes that it's the top of your noggin that offers the most accurate physiological data, and that was enough for us to give the hardware a quick look. The device itself is a small, square, rubber brick with an optical sensor covering one of the sides. Naturally, that side has to be pressed up against your skin in order to monitor your heart rate and body temperature, while an accelerometer records your moment. In order to get the Spree into its intended position, there's a rubber headband, which doubles as a sweatband, so, no matter how frantic your nodding, you won't be left wiping your eyes in sticky frustration.
