New

AltJIT

  • Allows sideloaded apps to use Just-in-Time (JIT) compilation
  • Go to "Enable JIT" > [Your Device] from the AltServer menu, then choose a sideloaded app
    • Your device must be on the same WiFi network as AltServer or connected to your computer via USB
  • JIT will remain enabled until the app is quit from the app switcher or purged from memory in the background
  • Requires iOS 14 or later

Direct .ipa Sideloading

  • Sideload apps (.ipa's) directly to iOS devices without installing AltStore first
  • Hold Option (macOS) or Shift (Windows) when clicking the AltServer icon to reveal new "Sideload .ipa…" menu option
  • Supports iPhones and iPads running iOS 9.3 or later
  • Supports Apple TVs running tvOS 9.3 or later (macOS)
    • For now, Apple TVs must be manually paired with Xcode first
  • Apps sideloaded with AltServer must be manually re-installed every 7 days
