JWX is a utility tool available for iPhone users, developed by Henrik Storch. It is a free app designed to enhance the user experience of those who use the JW Library App. JWX offers a unique feature that allows users to merge libraries from multiple devices into a single file for easy import back into JWLibrary. Please note that this feature is currently unavailable.

One of the key functions of JWX is simplifying the management of backups. Users can import backups directly into the app, save them on the device, or upload them to iCloud for synchronization across multiple devices.
