Free Apple apps for iOS 7 compatible devices
iPhoto, iMovie, Pages, Numbers, and Keynote are free on the App Store for qualifying iOS 7 compatible devices activated or purchased on or after September 1, 2013.
The first time you launch the App Store in iOS 7 on your qualifying new or factory-refurbished iOS device, you'll be offered iPhoto, iMovie, Pages, Numbers, and Keynote for free in addition to other free software from Apple.
When you tap Download All and sign in with your Apple ID, the apps will download to your device and appear in your account. If you tap Not Now when you see the offer, you can locate the apps in the App Store and download them one at a time for free. Any apps larger than 100 MB will download only when you're connected to Wi-Fi.
If your qualifying device came with iOS 6 installed, you'll be offered the apps after you upgrade to iOS 7. Any of the apps that you already purchased won't be available for free, but you can download the latest version of those apps for free.
