Installing iOS apps on older versions of iOS
If you have an older iOS device that is not able to install the latest version of iOS, you can still use the last version of that app available for your operating system.
- Buy and download the app on a newer device that runs a more recent version of iOS or download through iTunes on your computer.
- Launch the App Store on your older device and either search for the app or go to your Purchased tab.
- Click the Install button and iOS will warn you that you cannot download the latest version and will ask you if you want to download an older version that supports your operating system.
- Tap Download to accept and download the older version.
