Facebook acquires Helsinki-based fitness tracking app

Social networking site Facebook has acquired Helsinki-based fitness tracking app Moves in an undisclosed deal.

"We are joining Facebook's talented team to work on building and improving their products and services with a shared mission of supporting simple, efficient tools for more than a billion people," a statement from the firm read.

Earlier this year, Facebook bought mobile messenger WhatsApp for $19 billion and Oculus VR for $2 billion.

Facebook has confirmed to the Wall Street Journal (WSJ) that the Moves deal is "nowhere near the size of other acquisitions the company has made in recent months".

According to the Moves developer ProtoGeo, the application has been downloaded four million times for iPhone and Android phones since its launch in January 2013.

Moves continues to operate separately from Facebook.
