First up was iPhoto, which has been redesigned for iPhone and iPad in the same ultra-modern style of iOS 7. The layout is much cleaner and the photos appear larger than before. Apple is also adding the ability to construct a photo album on your iDevice and then order a physical copy directly from Apple.
iMovie receives a similar treatment, with much less clutter and larger icons. Browsing and sharing have also been simplified, and users can now select clips and tap to share them. New features for moviemaking include the ability to add picture-in-picture to clips and also speed up or slow down segments. Using iCloud, clips can be synced over all your devices as well as Apple TV.
GarageBand is now more capable, now allowing up to 16 tracks across all devices and a whopping 32 tracks on 64-bit devices. A new "Drummer" feature adds a controllable drum beat that can be manipulated to fit your tunes. Additional drummer "personalities" will be able to be downloaded via in-app purchases.
iLife is now free on all new iOS and Mac devices.
