Snappier navigation and a calmer sync engine. - Redesigned bottom tab bar with labels and a cleaner selected highlight — switching tabs is now instant and smoother. - Pull down to refresh your Library, Tools, and Chats; lists also refresh automatically when you switch back to them. - Fixed excessive iCloud-sync background activity that could loop and drain battery.

Fresh look for the reader and library. - New Liquid Glass tab bar that floats at the bottom, with a smooth morph between tabs. - Reader gets a minimalist refresh: the chapter-title header is replaced with two floating glass buttons (back and menu), and the bottom reading controls live in a single floating glass pill that includes your page progress. - Fixed: reading position sometimes appeared to reset when you closed a book and opened it again from the library. - Fixed: the reader could briefly revert to the default white theme after returning from background.

Reworked iCloud sync. Your library, reading progress, highlights, bookmarks, vocabulary, and chats now sync across every device signed into the same iCloud account, updating within seconds. Your existing library migrates automatically on first launch — nothing to set up. Also: bug fixes around sync enable/disable on slow iCloud connections, and a new "Remove device" option in iCloud Sync settings to prune old devices you no longer use.
