Pick up a Fit Meter to track your activity level throughout the day. This portable accessory records your steps and detects changes in activity level, altitude and atmospheric pressure, and can even estimate what kind of exercise you're doing aside from Wii Fit U. Using the built-in infrared technology of the Wii U GamePad, you can quickly and easily add this information to your Wii Fit U profile and chart your overall physical activity level during the day.
