With iOS 7, Apple adapted flat and minimalistic look for its icons, and is now taking that theme to its Apps on the App Store, as they leaked the new icons for iWork Apps, iMovie, iPhoto and Garageband.
According to Apple:
GarageBand is free on the App Store for all iOS 7 compatible devices; additional GarageBand instruments and sounds are available with an in-app purchase. iPhoto, iMovie, Pages, Numbers, and Keynote are free on the App Store for qualifying iOS 7 compatible devices activated on or after September 1, 2013
Also, some of Apple’s iWord and iLife Apps are free for users who bought the new iPhones, and Garageband is soon going free for everyone.
