Facebook Inc. has acquired mobile-fitness application Moves, as the social network jumps into the increasingly popular fitness-tracking market. Moves, which is operated by Finnish company ProtoGeo Oy, makes an app that works on Apple Inc. iOS devices and those that run on Google Inc.’s Android mobile operating system. The app lets people gather data from a smartphone’s accelerometer to determine whether a user is walking, running or doing other physical activities. With the Moves app, Facebook can enter the market
without developing its own wearable computing hardware. The app uses a
smartphone's built-in sensors to track a person's physical activity,
recognizing movements such as walking, cycling and running.
