About 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 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 will 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 store account. If you tap Not Now when you see the offer, you can search for the apps in the store and download them one at a time for free.
Note: If you aren't connected to WiFi when you accept the apps, any apps larger than 100MB will download when you have a WiFi connection.
If your new qualifying device came with iOS 6 installed, you will be offered the apps after you update to iOS 7.
If you already purchased and downloaded all the apps, they won't be available for free. You will, however, be eligible to download the updated versions.
