An APK (Android Package Kit) is the package file format used by the Android operating system for distribution and installation of mobile apps.

An XAPK is a package format for Android apps that contains the main APK file and additional OBB (Opaque Binary Blob) or split APK files, often used for large apps or games with significant data.

Yes, your safety is our priority. Our files are sourced directly from the Google Play Store and uploaded by verified users. Each file is scanned by Google Play Protect and undergoes additional integrity checks on our end. They are signed with SHA1, ensuring the file you download is the original, untampered version. You can download with confidence knowing our files are safe and secure.

For APK files, simply download and open the file. You may need to enable installation from unknown sources in your device settings. For XAPK files, you typically need a dedicated XAPK installer app or a file manager that supports the format to install them correctly, as they contain additional data or split APKs.
