Last January 2013, the Spree Biometrics Device was introduced to the market via the International Consumer Electronics Show in Las Vegas. This is actually the very FIRST device to capture your body temperature, movement and heart rate at the same time.

Peter Linke, President of Dallas-based Hothead Technologies, Inc., which developed the proprietary technology in Spree claimed that Spree Biometrics Device is the only device that can track the critical element of body temperature--which no other tracking device can perform, not even fingertip pulse oximeter.

Spree gauges your "body temperature, distance traveled, speed, time, heart rate and calories burned, and combines these data points into simple graphs that indicate when your body is hitting its ultimate stride". [businesswire.com]

So, how does Spree gather all the data? Through a wireless Bluetooth device. It will then relay real-time information from the headband device to the smartphone app. You can also download the data once it is stored.
