To use an app with an earlier version of iOS or OS X, you might need an earlier version of the app. For example, your iPhone with iOS 9 might be compatible with a different version of Pages than your iPad with iOS 7.
Here's what you need:
- iOS 4.3.3 or later on your iPhone, iPad, or iPod touch
- OS X Mountain Lion or later on your Mac
Here's how to find out if there's a compatible version of an app:
- Open the App Store or Mac App Store on your device.
- Go to your purchased apps:
- On your iPhone or iPod touch tap the Updates tab, then tap Purchased.
- On your iPad, tap the Purchased tab.
- On your Mac, click the Purchased tab.
- Find the app and download it. If there's a compatible version, a message appears and you can choose Confirm to get the latest version of the app that works for your device. If there isn't a compatible version and you can't download the app, go to the app's product page and contact the developer for help.
To get the latest version of an app, update to the latest version of iOS or OS X.
