AltServer: Simplifying iOS Sideloading
AltServer is a user-friendly application that makes it easy to sideload apps on iOS devices without the need for jailbreaking.
AltServer works by sideloading an app onto the user's iOS device, which means it is installed on the device without going through the App Store or requiring jailbreaking. The app can then be opened and used like any other app on the device.
One of the key features of AltServer is its ability to sign apps with a developer certificate, which allows them to run for a longer period of time than unsigned apps. This is particularly useful for users who want to develop or test their own apps, as they can continue to use them without having to constantly reinstall them.
AltServer also offers support for a wide range of devices, including iPhones, iPads, and iPod touches running iOS 12.2 or later. The software tool is available for download on both Mac and Windows operating systems.
AltServer is a powerful tool for iOS users who want more flexibility and control over which apps they can install on their devices.
