Bump is a cool little app that shares information between two phones that have been knocked together. Using the phone’s sensors, Bump determines which phones have just touched, and shares the selected information and files between the two handsets.
It is available on both Android and iPhone right now, so potentially should have a good userbase. I was going to trial Bump as an alternative to business cards at September’s Mobile Monday in Brisbane. However, most of the people I spoke to either did not have it installed or had not set up their details. I didn’t even take any business cards with me.
When I did get a chance to try it out, it was rather cool. As well as letting you manage your contact information through the application, you can also attach additional information, images and applications to be transferred. The only drawback I have encountered with this app is the lack of users, even in places where you think they should be.
