How to Install Scarlet App on Your iPhone or iPad

Check Device Compatibility

  • iPhones: Works from iPhone 6s onward, including models up to the latest releases.
  • iPads: iPad mini 4 and newer, iPad (5th gen and later), iPad Air (3rd gen and later), and all iPad Pro models.
  • iOS Version: Needs iOS 12 or above.
  • Storage Space: Keep enough free space for the app and any future IPAs.

iPod Touch is not supported. Always confirm your exact model and iOS version in Settings > General > About before installing.

Prep Your Device

  • Back Up: Safeguard your data with iCloud or iTunes.
  • Disable Find My iPhone (if required): In Settings > iCloud > Find My iPhone, switch it off.
  • Enable Developer Mode (on newer iOS versions): Go to Settings > Privacy & Security, find Developer Mode, and switch it on.
  • Stable Connection: Use a reliable Wi-Fi network to avoid interruptions.

Direct Installation Steps

  • Go to Scarlet Site: Open Safari and visit the official Scarlet page to get the latest installer or IPA file.
  • Tap Install: Press “Install” when prompted, then wait for the app icon to appear on your Home Screen.
  • Trust Developer: Go to Settings > General > VPN & Device Management (or Profiles & Device Management) and tap the Scarlet profile. Select “Trust” to allow it to run.
  • Open Scarlet: Launch the app and follow any on-screen prompts.

This method may need you to import a certificate (p12/provision file) within Scarlet. If so, follow the import prompts and provide the correct password when asked.

Using iTunes or Finder (DFU Mode)

  • Download Scarlet IPSW: From the Scarlet site, grab the custom IPSW file if provided.
  • Connect Device: Plug your iPhone or iPad into a PC or Mac with the latest iTunes or Finder.
  • DFU Mode: Press and hold the Home (or volume down on newer devices) + Power buttons for about 10 seconds, then release Power while still holding Home/volume down for 5 more seconds.
  • Restore with IPSW: In iTunes/Finder, hold Shift (Windows) or Option (Mac), click “Restore iPhone/iPad,” and select the Scarlet IPSW. Wait until the process completes.
  • Set Up & Trust: After the restore, set up your device, then trust the Scarlet developer in your settings.

Using AltStore

  • Install AltStore: Download AltStore on your computer from its official site, then connect your iPhone or iPad.
  • Launch AltServer: Follow prompts to install AltStore onto your device.
  • Import Scarlet IPA: In the AltStore app on your device, tap the “+” icon and pick the Scarlet IPA file.
  • Trust Profile: Head to Settings > General > VPN & Device Management and trust the Scarlet profile.

AltStore keeps the app signed, reducing certificate revocations and making the process simpler over time.

Troubleshooting Common Issues

  • Installation Fails: Check for enough storage and retry on a stable network.
  • “Not Trusted” Error: Revisit VPN & Device Management and trust the correct profile.
  • App Crashes: Make sure the certificate is correctly imported or re-download the IPA. A quick device restart can also help.
  • Missing IPA Support: Ensure the IPA is compatible with your iOS version.
  • Stuck or Frozen: Close the app, clear multitasking, and relaunch. If needed, reinstall Scarlet.
Once Scarlet is installed and trusted, you can sideload more IPA files by opening Scarlet and selecting “Import” or “Sideload.” Always download IPAs from reliable sources and keep your device updated for the best performance. If you face repeated issues, check for new Scarlet versions or consult their official support page.
