Bump is a free iPhone app that makes swapping phone numbers and contact information simple and fun. After you setup your profile contact card in the Bump app, just find another person who has the same iPhone app and bump fist with them to swap your contact information with them. To setup Bump, you can choose what you want to share, such as phone, email, photo, and other contact settings easily from your own profile in the Contacts app, or enter it manually. We think bump is quite unique in its approach to contact swapping and makes a tedious task fun and painless.
Note: The Bump app stores you information securely on its servers. After you bump iPhones, you will have to confirm the transfer to avoid passing information by mistake.
