Check for app updates

You can setup apps to update automatically in Settings > iTunes & App Store, but make sure that your apps are up to date:

1. Open the App Store and tap Updates. If updates are available, tap Update All.
2. If  prompted, enter your iTunes Store account information. App Store will then download and install the app updates.

Note: If it is a paid app, ensure you are using the iTunes account you purchased the app with originally. If it is not, you may be asked to purchase the app again. Learn more about downloading previously purchased items.

Cheers,

- Judy
