What’s the Problem?
Getting the app onto the iPad is only part of the problem. Most apps are built for a newer version of iOS, so the current version of the app won’t work on the original iPad running iOS 5.1.1. However, assuming there is a version of the app that runs on the older operating system, you can put it on your iPad.
First, try to download the app through the App Store on the iPad. In theory, this process should work, and for apps that have an original iPad-compatible version available, the iPad should prompt you to download the older version. At this point, confirm that you want to download the old version. In practice, this process doesn’t always work, but there is a neat trick that can help you get over this App Store hurdle.
How to Download Apps to the First-Generation iPad
The trick here is to go around the App Store to make the purchase on a computer and only use the App Store on the iPad to download the already purchased app. You do this by using iTunes on your PC or Mac to make the purchase. In 2017, Apple removed the App Store from iTunes, so you need an older version of iTunes.
Download iTunes 12. 6. 3, a version of iTunes with the App Store included. Apple no longer has iTunes 12. 6. 3 for Macs available on its website. If you already have it or an older iTunes version with the App Store, you can still try this method. Once downloaded and installed, you have access to the App Store through the iTunes app on your computer. If you use Windows, you need to remove the previously installed version of iTunes before installing the older version. Launch iTunes and verify that you are signed in to the same Apple ID as you use with your iPad. View these settings under the Store menu. The View Account choice shows the email address used with your iPad. If they aren’t the same, choose Sign Out and sign in with the same account used on the iPad. Purchase an app through the App Store in iTunes on your PC or Mac. This process is similar to downloading apps on your iPad. Once in iTunes, go to the iTunes Store and change the category on the right from Music to App Store. The screen changes to resemble the App Store app on your iPad. Click the Get button or the price button to download the app to your computer. Go to the App Store app on the iPad, choose the Previously Purchased tab and locate the app you just downloaded on your PC. Tap the cloud button next to the app to download it onto your iPad. (You don’t need to connect the iPad to your computer for this step. ) The iPad may prompt you with a message telling you that the app is not supported on your version of iOS. (If it doesn’t, the app supports the first-generation iPad). If there is a version of the app that supports the original iPad, the iPad prompts you to download a previous version of the app. Tap Yes to download a version of the app compatible with your iPad.
Once downloaded and installed, you have access to the App Store through the iTunes app on your computer. If you use Windows, you need to remove the previously installed version of iTunes before installing the older version.
