Alright this is a pretty cool app available for FREE at the moment. Start mixing your own music with the app djay for iPhone – algoriddim available for free right now. Here’s a quick blurb about this app: djay transforms your iPhone or iPod touch into a full-fledged portable DJ system and seamlessly integrates with your music library, giving you direct access to all your favorite tracks and playlists. A hyper-realistic touchscreen interface and ultra-low latency converge to offer you a true professional mixing experience, right in the palm of your hand. You can perform live, record mixes on-the-go, or enable Automix mode and let djay mix your favorite playlist from your music library automatically.
I just downloaded on my phone and is a good way to transform “slowish” songs into songs with a faster beat and perfect for working out or just listen to while you clean or do whatever.
