hand-built for each
A native catalogue for iPhone, iPad, Mac, and Apple Watch. Scan books fast, sync through your private iCloud account, and use Siri, widgets, and Shortcuts.
Athos 1.2 brings category and publisher tidy-up tools, faster scanned-batch saving, clearer iCloud activity, and a refreshed Apple Watch experience.

iPad uses a three-column split view for navigation, collection list, and book detail, with keyboard, trackpad, Pencil, and Stage Manager support.

The Watch app keeps reading actions close: view the current book, log a session, or mark it finished.
