Added an in-app camera with a mouth alignment guide, front and rear camera switching, and optional mouth-area cropping. Press and hold “Add Photo” to open the camera quickly for everyday progress photos. Added two-column grid and carousel views alongside vertical photo browsing, with improved scrolling, transitions, and browsing-position restoration. Correct the actual date and time of an aligner change, preview how related records and photo assignments will be affected, and undo eligible corrections. Assign manually added records to the current or previous aligner for more accurate tracking on change days. Refined buttons, dialogs, and notifications, improved today’s wear-time display, and enhanced support for dark mode, increased contrast, and larger text.
