Last month mobile-to-mobile communications company Bump decided to share its technology, which allows for data transfer between two iPhone or Android phones. For example, its flagship iPhone app swaps contact info and photos when two phones "bump" (as in "fist bump") near each other. Bump introduced an API, but to little fanfare.
A brand new iOS messaging/social app called Peach has rocketed in popularity since launching last Friday. A developer has reverse engineered the Peach API and created clients for Swift and Mac. The clients have been posted on GitHub for developers interested in using the undocumented Peach API.
