iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Algoriddim's Djay Arrives on iPhone and iPod Touch
Back in November, we first previewed a version of Algoriddim's Djay for iPad which took advantage of the new iOS 4.2 firmware to provide a low latency DJ experience on your iPad. The company has just released an iPhone and iPod Touch version of the app that offers many of the same features as the iPad version. While some were quick to note that such a system wouldn't be used by DJ's in a professional setting, it's still a very impressive use of the audio capabilities of the the most recent versions of iOS.
The iPhone version includes iPod library access, automix, beat matching, recording capabilities, and many of the same effects as the iPad version. The iPhone version is $9.99 [App Store] and is distinct from the iPad version which sells for $19.99 [App Store]
