Google buys photo, contacts transfer app Bump

Bump app
Bump makes it easy to transfer photos and files to nearby users.

Google has acquired Bump, the maker of a smartphone app that allows users to share files by bumping devices together. 

The two companies did not release financial terms of the deal. 

In a blog post announcing the acquisition Monday, Bump CEO David Lieb said the company's apps, which also include a photo-sharing service, Flock, will keep working for now. 

In a blog post from late March, Bump said that its namesake app was downloaded 125 million times. The Bump app was launched more than four years ago. 

"The Bump team has demonstrated a strong ability to quickly build and develop products that users love, and we think they'll be a great fit at Google," Mountain View, Calif.-based Google said in an emailed statement. Bump is also based in Mountain View. 

On its FAQ Web page, the company explains the app like this:

There are two parts to Bump: the app running on your device and a smart matching algorithm running on our servers in the cloud. The app on your phone uses the phone's sensors to literally "feel" the bump, and it sends that info up to the cloud. The matching algorithm listens to the bumps from phones around the world and pairs up phones that felt the same bump. Then we just route information between the two phones in each pair.

Bump is a free app, and works with iOS and Android devices.
