An IPA (iOS App Store Package) file is an archive file format used by Apple's iOS operating system to store iOS apps. Essentially, it's the equivalent of an APK file for Android devices. IPA files contain the complete app data required for installation.
Sideloading is the process of installing apps directly onto your device without using the App Store. Tools like AltStore, Sideloadly, or Xcode can help you sideload IPA files onto your iOS device.
Jailbreaking unlocks advanced customization and allows you to install apps and tweaks unavailable on the App Store. After jailbreaking, you can easily sideload IPA files or use package managers like Cydia or Sileo.
Ensure you download IPA files from trusted sources to avoid malware or security issues. Sideloading and jailbreaking may void your warranty, so proceed with caution.
