Apple has announced new versions of the iLife apps: Garage Band, iMovie, and iPhoto. All now have a new look for iOS 7, and all have some great new features, including desktop-class effects for iMovie.
And amazingly, Garage Band can now do 16 tracks, and even up to 32 tracks on 64-bit devices—and that's on an iPhone or iPad. Garage Band also has a new feature called Drummer. All the apps are now free and available today, and are free with the purchase of a new device.
