Every record, easier to revisit.
From standardized capture to visit preparation, YAJI is designed around the real moments of an orthodontic journey.
Standardized capture
Nine standard views—five intraoral, four facial—with on-screen guides for consistent framing, then reposition, zoom, and rotate after capture or import.
Records & timeline
Switch between calendar, timeline, full-size, and thumbnail views, and organize photos, tags, notes, and appointment milestones in one chronology.
Same-view comparison
Choose the same view on two dates and compare stacked, side by side, with a wipe, or as an overlay—plus vertical, horizontal, or crosshair guides.
Angle measurement
Place three landmarks on a photo to read the angle, with worked examples for common profile angles. YAJI publishes no normal ranges and does not judge whether a reading is abnormal.
Change videos
Render same-view photos into a timelapse on-device, with a date that advances through the footage and the YAJI mark on every frame.
Local reminders
Daily or weekly record reminders, plus appointment alerts one week, three days, one day, and the day of the visit—all scheduled on your iPhone.
Visit-summary PDF
Pick a date range and views to generate an A4 summary on-device with comparisons, highlights, and a timeline; preview it and share only when you choose.
Album filing & watermarks
Exported photos and videos carry the YAJI mark and the record date, and can be filed automatically into a dedicated “牙记 YAJI” album. Originals in the app stay untouched.
This policy applies to the current version of YAJI. YAJI is a personal record-keeping tool and does not provide diagnosis, treatment assessment, or medical advice.
