If you're looking for an iOS app to sign and install IPA files on your device, download AltStore. While it doesn't install the files directly on your iPhone, by running AltServer on your desktop and connecting to your iPhone, it will accomplish the task.

Download AltStore for Windows, macOS, or Linux.

What is AltStore?

AltStore is a free iOS app that enables you to install IPA files on your device without jailbreaking it. With the free certificate, you can install up to three apps that will remain functional for seven days before needing to be re-signed by AltServer to prevent expiration.

Cydia Impactor is no longer functional with free certificates, making AltStore the go-to app for this purpose. The workaround for signing IPA files behind AltServer is also utilized on other tools to sign and install IPA files on iPhones such as Sideloadly, Bullfrog Assistant, or SideStore.

AltStore is compatible with iOS 12.2, iOS 13, iOS 14, iOS 15, and the latest iOS 16. It can now also sideload IPA files directly to iOS devices without the need to install AltStore first. This can save you 2 slots. To access this feature, hold down the Option key (on macOS) or the Start key (on Windows) while clicking the AltServer icon, which will reveal the “Sideload .ipa…” menu option.

AltStore was initially created to install Delta (an all-in-one emulator for iOS),but the developer later decided to allow other users to distribute their apps through the IPA signing tool as well.

By using AltServer, you can install IPA files with your Apple ID over Wi-Fi, re-sign apps in the background to prevent them from expiring, and handle all app updates through AltStore, which must be installed on your iPhone or iPad. Note that all operations require that AltServer is installed and running on your computer and the iDevice is connected to the same Wi-Fi.

In addition, AltStore allows you to deactivate installed apps, enabling you to switch between a max of 10 apps without the 3 app limit. This means that you can install up to 10 apps on your iOS device and switch between them as needed. It also works with a paid developer account.

Note: App containing extentions on non-developer Apple IDs are limited to creating 10 App IDs per week. App extentions often used in tweaked apps count towards this limit.

You can download IPA files in the Safari browser and send them directly to the AltStore app for signing and installing. Starting from version 1.4 (which requires a minimum of iOS 14),there is an added option to refresh apps through the Siri and Shortcuts app, as well as support for a Home Screen widget that displays the expiration time of sideloaded apps.

AltStore IPA can also be installed on any modern jailbreak such as unc0ver or XinaA15. Furthermore, the developer has released AltDaemon, which can be installed on jailbroken devices. This allows AltStore to install and sign apps without the need for AltServer on a computer, making it a self-sufficient IPA signing tool for jailbroken iOS devices.

AltStore is packed with accessibility for VoiceOver users, as well as support for 3rd party sources with IPAs and URL scheme for adding sources directly. This last feature allows you to download and install IPA files automatically on your device.

The possibilities offered by the tool don't end here. AltStore and AltServer are known for their support for the jailbreak community. As a result since AltStore 1.4.8 allows you to install unc0ver's Fugu14-based untethered jailbreak (works after restart) on iOS 14.3 – iOS 14.5.1.

There's more. When Psychic Paper exploit was released for iOS 13 – iOS 13.4 AltStore was implemented not only to install, but also to allow Filza Escaped to view and manage all files on your device without jailbreak. The exploit was fixed with iOS 13.5 beta release.

One of the last features implemented to AltStore is support for AltJIT. With Just-In-Time (JIT) compilations supported apps can be compiled natively on the device allowing them to run at full speed. As an example, Delta JIT compilation doubles the Fast Forward speed from 1.5x to 3x.

With JIT compilation supported on iOS 14.2 – iOS 15.4, emulation apps can now run at full speed and performance. This feature is provided by iOS, but was never been publicly mentioned by Apple. JIT apps are not available at App Store, only sideloaded apps can handle this feature.

Besides Delta emulator, also UTM (virtual machine for iOS) and DolphiniOS (GameCube and Wii emulator for iPhone and iPad) apps work with AltJIT. To run apps in JIT mode simply tap on an app icon and activate 3D Touch and select from the context menu Enable JIT if available.

AltServer and AltStore were never released officially for Linux, but there are available forks of the project via GitHub AltServer Linux and AltServerGUI Linux. Riley Testut is responsible only for the AltStore Windows and AltStore macOS releases installed via AltServer.

If you are running a device without jailbreak you can try the TrollStore app. It uses the CoreTrust bypass bug to install permanently apps on stock iOS, and it doesn't require a jailbroken environment. It works on iOS 14.0 up to iOS 14.8.1 and iOS 15 up to iOS 15.4.1.

Due to the licensing of certain dependencies used by AltStore, the developer released the software under the AGPLv3 open-source license via the GitHub Repo. To compile the code, you will need Xcode and Swift 5+ for iOS 12.2+ (AltStore) and macOS 10.14.4+ (AltServer).

AltStore was primarily written in Swift, with 91% of the code being in that language. Riley Testut has also provided the source code for all of its components, including AltPlugin, AltServer, AltWidget, AltStore, and AltDaemon allowing everyone to learn how the app works.
