iPhone: Exchanging contact details with someone is a notoriously annoying process. It normally involves rummaging around for business cards or frantically trying to remember your own phone number.

Mac: Virtual DJ is a complete music mixing application for your desktop, allowing you to dump your vinyl turntables for a laptop. Looking like a classic DJ set-up, with a mixer and two decks, Virtual DJ will be instantly accessible to DJs and newcomers alike. There's a BPM counter to help you judge transitions between tracks, and the visual wave display also helps to cue up your music so that you sound like a pro.
