Nintendo has unveiled the Fit Meter, a peripheral you’ll be able to use with and independently of the upcoming Wii U game Wii Fit U. You attach it to your clothes and the Fit Meter will monitor your daily activity. You can then transfer this data to Wii Fit U, keep track of your progress and complete challenges.
It would be cool if they added an app like this to the Nintendo 3DS, which already keeps track of your steps. Check out the introductory video below.
