To sideload apps with AltStore, first choose the right version: AltStore Classic works worldwide but needs a Mac or Windows PC running AltServer and requires app refreshes every seven days. AltStore PAL is an alternative marketplace with regional, account, browser, and iOS/iPadOS requirements. The installation steps below cover Classic; PAL has a separate download and eligibility process.

AltStore Classic or AltStore PAL: which should you use?

AltStore offers two different routes, not interchangeable installation methods. Its site describes Classic as available worldwide and PAL as an alternative app marketplace. AltStore says its products are not associated with Apple. See the AltStore overview for its current product information.

Factor AltStore Classic AltStore PAL
Availability Described by AltStore as available worldwide. AltStore overview Current download instructions require physical presence in the EU, Japan, or Brazil, and an App Store account set to one of those regions. PAL download instructions
Installation route Install AltServer on a Mac or Windows PC, then use it to install AltStore on the device. AltServer guide Use AltStore’s separate download flow; the current instructions specify Safari, Chrome, or Vivaldi. PAL download instructions
Device software Enable Developer Mode on iOS 16 or later as part of installation. macOS guide Windows guide Current download instructions require iOS/iPadOS 18.0 or later. PAL download instructions
Ongoing user maintenance Sideloaded apps expire after seven days unless refreshed. Getting started AltStore’s developer comparison says PAL apps do not expire for users. Developer overview
Computer Required to run AltServer for the standard install and refresh process. AltServer guide The listed PAL download requirements do not specify a computer. PAL download instructions

PAL eligibility and distribution rules can change; confirm the current requirements on AltStore’s download page before starting. AltStore’s developer comparison also describes a paid Apple Developer account requirement and a 5% Apple Core Technology Commission for PAL distribution. Those are developer-side conditions, not fees charged to every person installing or using PAL.

What you need for AltStore Classic

  • An iPhone or iPad and a Mac or Windows PC.
  • A supported computer operating system: AltStore’s current overview lists macOS 11 or later and Windows 10 or later for AltServer. The macOS guide also mentions AltServer 1.6.2 for macOS 10.14 and 10.15; if you use one of those older versions, consult that guide’s compatibility notes rather than assuming the current download requirements apply. AltStore overview macOS guide
  • A USB data connection or Wi-Fi sync between the device and computer. USB is optional if Wi-Fi sync is configured. AltServer guide
  • Your Apple ID credentials for AltServer to authenticate with Apple. AltStore says the credentials are sent only to Apple, not to AltStore or others. macOS guide

Install AltStore Classic on macOS

  1. Download and place AltServer. Download AltServer for macOS and move AltServer.app to the Applications folder. Follow AltStore’s macOS guide for the current download and compatibility details.
  2. Open AltServer and connect your device. Launch AltServer, connect and unlock the iPhone or iPad, then tap Trust if the device asks whether to trust this computer.
  3. Set up Wi-Fi sync or use USB. In Finder on modern macOS, select the device and enable Wi-Fi syncing. Older systems may use iTunes. Alternatively, leave the device connected directly by USB. AltServer connectivity instructions
  4. Install AltStore. Open AltServer from the menu bar, choose Install AltStore, and select your device. Enter your Apple ID credentials when prompted so AltServer can authenticate with Apple.
  5. Trust the developer profile and enable Developer Mode if prompted. On the iPhone or iPad, follow the profile-trust prompt.

Use the guide for your system for exact current prompts. macOS guide

Install AltStore Classic on Windows

  3. Connect and trust the device. Unlock the iPhone or iPad, connect it to the PC, and trust the computer when prompted. In iTunes, enable Wi-Fi sync if you want to install or refresh without a cable.
  4. Install AltStore. Open AltServer from the taskbar’s notification area, choose Install AltStore, and select the device. Enter your Apple ID credentials for Apple authentication.
  5. Complete device trust and Developer Mode steps. Trust the developer profile if prompted. On iOS 16 or later, enable Developer Mode under Settings → Privacy & Security. See the Windows guide for current labels and troubleshooting.

For refresh to work, AltServer must be running and reachable: the iPhone or iPad needs to be on the same Wi-Fi network as the computer or connected directly by USB. AltStore recommends launching AltServer when the computer starts and leaving it running. This is why a cable is not mandatory, but the computer remains part of the Classic refresh setup.

Optional advanced route: install an IPA directly

AltServer release notes describe an option to sideload an IPA without first installing AltStore. Those direct installs must be manually reinstalled every seven days, according to the release notes. Installing AltStore is the more convenient standard route because it enables automatic refresh. AltServer release notes
