Mix your music and experience an artistic adventure: iPhone apps of the week

The big news this week from the world of Apple was the discovery that iPhones have been tracking users' locations as they go about their daily lives. Apparently, whenever you use Google Maps, or take a picture, or do anything that consults the GPS, your location and a time stamp are recorded in a log file on your iPhone.

Djay app lets you spin iTunes from your iPhone

Algoriddim's Djay is a $49.95 Mac application that lets you spin your iTunes library in a virtual two-turntable setup.

Djay's interface stays fairly faithful to the old-school turntablist tradition, with a crossfader, cue points (which let you mark a record at specific spots so you can move the stylus to the desired part of a song), and virtual "scratching," enabled by dragging your cursor across the vinyl on the screen. At the same time, Djay offers digital conveniences such as automatic beat matching and tempo synchronization. In addition, its Automix feature creates a mix on … Read more
