Algoriddim's surprisingly powerful DJ software has been updated with extensive iCloud support for iOS 5. Djay, which is available for iPad or iPhone, "transforms your iPad into a full–fledged DJ system and seamlessly integrates with your iPod library." Djay includes a wide variety of professional DJ features, audio effects and even supports pre-cuing with a cable from Griffin.
In the latest 1.4 update, Djay adds iCloud integration (backup and sync your song settings such as cue points, edited BPM, etc. over the air, across all of your iOS devices running djay), AirPlay integration, lock screen integration (displays currently playing song info including artwork), sort library by BPM, and a number of different audio FX.
