AltStore – Install IPA Apps Without Jailbreak

AltStore is one of the most popular tools for sideloading IPA apps and games on iOS devices. It lets you install apps outside the App Store safely, without needing a jailbreak.

You can use AltStore to run emulators, tweaked apps, and modded games that Apple normally doesn’t allow. It works by using your Apple ID and a companion app called AltServer (available for Mac and Windows) to install and refresh apps automatically.

✅ Supports iOS 17, iOS 18+, and the latest iOS 26
✅ No jailbreak required
✅ Refreshes apps to stop them from expiring
✅ Add custom sources for more IPA downloads

Why Use AltStore?

  • Install apps outside the App Store
  • Keep sideloaded apps active with automatic refresh
  • Works on both Mac & Windows
  • Supports Custom Sources – Add third-party repositories.
  • 100% safe and jailbreak-free
