Since we live in an age of “there’s an app for that”, it really should come as no surprise that there are performance activity monitoring equipment like the BodyMedia FIT and other products that can sync with a smartphone.
Now there is the Armour 39 from Under Armour Inc., which is essentially a chest strap filled with sensors that can send data to a user’s smartphone. It can somehow calculate the “Willpower”, which is a system of measuring the heart rate, calories burned, and somehow narrows all this information on a scale of 0 to 10.
Nike has a similar product known as the FuelBand which does essentially the same thing, and has been around since 2006 with the Nike and the iPod Sport Kit.
I believe that Under Armour is contemplating the future with a projection onto clothing, as you can see in this illustration on the right. This can be done with some sort of embedded touchscreen fitness tracker with a bodysuit’s fabric.
If you want the Armour39 now, it costs $149.99, and a watch that can sync with it costs about $199.99.
