This is made possible by exploiting a loophole in the Xcode developer platform, which allows developers to sideload their own apps.

Here are some of the key features and requirements of AltStore:

By using AltStore, you can access apps that push the boundaries of iOS in ways not possible with Apple's app review system, making it a great option for those looking to try new and innovative apps.

Safety and Security

AltStore has implemented measures to ensure user data is securely handled. According to its developer, Riley Testut, user data is not sent to third-party servers but is instead sent directly to Apple for verification and stored securely on the device.

While AltStore itself is safe, the safety of the individual apps (IPAs) you install is not guaranteed. Users are advised to only download apps from reputable sources to avoid malware or potentially harmful applications.

The risk arises from the nature of sideloading apps, which can bypass the App Store's review process, making it essential to be cautious when installing apps from outside the App Store.
