Algoriddim has released an iPhone version of djay, which is available to download in the App Store for $9.99. Much like the Mac and iPad version of the application, djay for iPhone transforms your handset into “a full fledged DJ system,” allowing users to add tracks from their music library, and mix them on the go. If you have a Mac computer, you can get this free demo. Currently, djay for iPhone is available in the App Store for $9.99. The iPad version costs $19.99, and the Mac version is available for $49.99.
