CLEAR TRAY-CYCLE PLANNING Set your current tray, total number of trays and change interval. See your current stage, goal streak and next planned tray change from the Today and Progress screens. PHOTO PROGRESS JOURNAL Add teeth photos from the camera or photo library and revisit them by date, so small changes are easier to notice over time.
