We like this idea. Yet another slice of curious software for a jailbroken iPhone or iPod touch, SynchStep analyses the pace at which you walk or run in order to choose songs from your music collection which match your pace.

What this means is every step you take is marked by a beat - a drum slap, bass pluck, riff or chord. The developers built the software to help music fans who have grown tired of making the same musical choices, as the software will select the song in your library that most matches your gait.

SynchStep will select and play a song once it has analysed your pace, which takes a few seconds.

“Unlike other music players, SynchStep connects the music in your head to the music in your body. You don't have a lot of control over what comes on; it's liberating,” the developer said.

SynchStep was originally available as a hand-made, custom built MP3-player sporting a display-less experimental interface. The device only used an on-off switch and it was given to people age 10 to 65 to play with. Manufacturing the device cost too much, so the developer simply ported the solution to the iPhone and iTouch.

The software’s available for free, along with full instructions on how to jailbreak your iPhone or iPod touch in order to install SynchStep.
