Seamless is an elegant app created by Five Details that makes it possible to listen to iTunes without interruption when transitioning between Mac and iPhone or iPod Touch. Adam Lisagor (aka lonelysandwich) demonstrates Seamless in action.
Meet Seamless. When you’re ready to transition music from iTunes to iPod, tap Seamless on your phone, and boom. The music fades out on the Mac, and fades in on the phone.
Beat: better than ever.
