The world's most popular social network has just snapped up Moves, the smartphone activity app.
Moves made the announcement on Thursday, saying that the app would remain a standalone product and that the company was "delighted" to be joining Facebook.
"Now, we're 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," the company said in astatement.
Launched in January 2013,Movesis a fitness tracking app that functions as an activity diary with the user's smartphone automatically doing the recording. For instance, it automatically recognizes the difference between walking, running and riding a bike. It has proved a huge hit among iPhone owners since landing on the App Store.
This is the third headline-grabbing acquisition that Facebook has made in as many months.
As well as Moves and its parent company, Finland-based ProtoGeo Oy, the company has also snapped up WhatsApp and virtual reality technology firm Oculus since February.
