AltStore

AltStore, conceived and crafted by developer Riley Testut, is a third-party app store tailored for iOS devices. A standout feature of AltStore is its ability to grant users the capability to install applications on their iOS devices sans the need for jailbreaking. This innovative approach hinges on the method known as "sideloading," which facilitates app installations. Users can conveniently sideload apps onto their iOS devices by connecting to a computer and leveraging AltStore's companion desktop application, which adeptly signs and installs the chosen apps onto the target device.

Adding to its repertoire, AltStore introduces a unique functionality dubbed "App Delta Updates." This distinctive feature streamlines updating sideloaded apps, allowing users to initiate updates directly from within AltStore, enhancing efficiency and user convenience.

AltStore also boasts an expansive catalog comprising various apps and games for users to peruse and select from. This collection includes emulators, utilities, and other software that may not be accessible via the official App Store. Emphasizing a developer-centric approach, AltStore provides a platform for developers to distribute and share their apps, granting them an avenue to reach users without navigating Apple's stringent review procedures.

For those interested in utilizing AltStore, a free Apple ID is typically a prerequisite. Developers seeking to distribute their creations through AltStore may find an Apple Developer account valuable. Compatibility is a crucial hallmark of AltStore, accommodating both Windows and macOS computers, allowing users to sideload apps from either platform onto their iOS devices.
