Published by Amadeus on

We all know to install apps from Apple’s App Store, but if you download an app’s IPA file, you may not know how to install it. So this tutorial will give you the simplest way to install apps and IPA files on iPhone.

Content Summary:

What is an IPA File

An IPA file is a file with an IPA extension. It is similar to a ZIP file; it contains the installation information of an app. The IPA file is designed especially for iOS devices; you can’t use macOS, Windows, Android, or other systems to install it. When you back up your app files using iTunes, you can see .ipa files in a folder. Installing an IPA file is not as easy as Android APK, but don’t worry; this article will help you.

The Ordinary Way – Use iTunes With AppleID

Most users know how to install apps using iTunes; it is a common way to install IPA files – if you’re still curious, check out this tutorial.

But to use the iTunes installation, you must have purchased the app from the App Store using your Apple ID. You can’t use iTunes if you download an IPA file unavailable on App Store. When iTunes installs an app, it checks whether the Apple ID of the app is the same as the Apple ID on your device. If not, the app will flash back after installation.

At this point, you can use iOS sideloaded applications. It is easy to sideload iOS apps and doesn’t require jailbreaking the device. The key to sideloading iOS apps relies on Apple developer certificates. Apps and IPA files authorized by the developer certificate can be installed directly on the iPhone without needing an Apple ID.
