An IPA file is an iOS application archive file. iOS users often use these files to install apps outside the official App Store. This process is called sideloading. Apple strictly limits sideloading to maintain security and control. However, tools like Scarlet have emerged to make sideloading easier for average users.

SCA Free, short for Scarlet Certificate Authority Free, is a feature offered by Scarlet Antirevoke that allows users to install IPA files without a paid certificate. With SCA Free, you can generate a free certificate that can be used to install IPA files on your device.

Unlike AltStore, Scarlet does not enforce a strict three-app limit when using enterprise certificates.

Apple requires Developer Mode to be active to run sideloaded apps. Open on your iOS device. Navigate to Privacy & Security . Scroll to the bottom and tap Developer Mode . Toggle the switch to On . Restart your device when prompted. After rebooting, tap Turn On and enter your passcode. 2. Prepare Your IPA Files

For the iOS jailbreak and sideloading community, "revokes" are the enemy. You install a tweaked app or emulator, and days later, it crashes upon opening because Apple has revoked the developer certificate used to sign it. This is where —and specifically its "SCA" (Scarlet Antirevoke) feature—has made a massive name for itself.
