Originally released in 2012, the first web version supported only the transfer of photos, from phones to computers. With the recent release, users can now save photos and videos from a smartphone to a computer hard drive, and between devices. Users can also back up contacts on a computer and reload them on a new device, or move presentations from one computer to another.

How Does It Work?

There are two parts: the app running on a device and a smart matching algorithm running on servers in the cloud. The app 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. Information is then routed between the two phones in each pair.

A strong connection to the Internet is needed so the app can communicate with servers. Standard data plan rates will apply. In addition, location services must be turned on. Users must also authorize the use of their location information in order for the app to work correctly.

Bump currently supports iPhone, iPod, iPad, and Android, and works cross-platform between them all.
