Download AltStore IPA installer for iOS

Kuba Pawlakqbap | iOS Apps

When you are searching for an iOS app to sign and install IPA files directly on your device AltStore is your man. It doesn't exactly do it on your iPhone but if you running AltServer on your Desktop and it's in the same Wi-Fi network as your iPhone it will do the job.

Download AltStore for Windows, macOS, or Linux.

What is AltStore?

AltStore is a free iOS app allowing you to install IPA files directly on your device without the need to jailbreak your iPhone. With a free certificate, you can install up to 3 apps that will work for 7 days without revoking. AltServer can re-sign all apps to prevent them from expiring.

Cydia Impactor is not working anymore with free certificates and AltStore was the first app to fill the gap. The technology behind AltServer is used also by Sideloadly to sign and install IPA files on iPhones and iPads. Riley Testut did an excellent job finding a workaround to sign IPA files.

AltStore works with iOS 12.2, iOS 13, iOS 14, and the latest iOS 15. It can now also sideload IPA files directly to iOS devices without installing AltStore first. Hold Option (macOS) or Start (Windows) when clicking the AltServer icon to reveal the new "Sideload .ipa…" menu option.

For the initial release, AltStore was created to install Delta (all in one emulator for iOS) but the developer decided to allow other users to distribute their apps through the IPA signing tool.

Use AltServer to install IPA files with your Apple ID over WiFi, re-sign apps in the background to prevent them from expiring, and handle all app updates through AltStore installed on your iPhone or iPad. All operations require to run AltServer in the same WiFi network as your device.

What's more, AltStore can deactivate installed apps allowing you to switch between apps (max 10) without the 3 app limit. This way it's possible to install up to 10 apps on your iOS device and switch between them when needed. The app works also with a paid Apple developer account.

Download IPA in the Safari browser and send the files directly to the AltStore app for signing and installing. Since version 1.4 (min. iOS 14 required) there is included an option to refresh apps via Siri and Shortcuts app, support for Home Screen widget displaying sideloaded apps expire time.

AltStore can be also installed on any modern jailbreak like unc0ver or Taurine15. Using a modified version of the IPA signing tool for iOS the AltStore app will not get revoked.

Furthermore, the developer released AltDaemon for all jailbroken devices via Chariz Repo. It allows AltStore to install and sign apps without using AltServer on a computer. This feature makes AltStore a self-working IPA signing tool for iOS, exactly like ReProvision.

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 AppStore, 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 15.1.1.
