This thing does whatever it says on the tin- it's a metronome, which means it keeps track of music tempo. You can make your own sounds for it by clapping you hands to the beat, and there's Donkey Kong in it. Will be out in Japan by the time you read this, and has about as much purpose as the Mario Calculator and Animal Crossing Clock. Like all the near-pointless apps before it, Donkey Kong Metronome costs a measly 200 Nintendo Points.
