## What is YAJI?

YAJI is a private, on-device journal for people with fixed braces or clear aligners. Build a consistent visual record, compare changes over time, and keep notes and reminders organized between appointments.

GUIDED PHOTO RECORDS
• Capture up to nine guided facial and intraoral views, or create a custom view.• Take photos in sequence or import existing images.• Review records by calendar, timeline, full-size image, or grid.• Add notes, observation tags, tooth or location details, and follow-up items.

COMPARE OVER TIME
• Compare the same view from two dates side by side or stacked.
• Use slider, overlay, alignment, and reference-line tools for closer visual review.
• Create a progress video from a series of same-view photos.
• Add three-point angle annotations to profile images for personal reference.

REMINDERS AND ALIGNER TRACKING
• Set daily or weekly record reminders and appointment reminders.
• Record appointment dates and add notes after each visit.
• Choose fixed-braces or clear-aligner mode for relevant tracking.
• In clear-aligner mode, track treatment phase, current tray, planned wear time, and aligner-off time.
• View aligner-off timing through Live Activities on supported iPhone models.

PRIVATE BY DESIGN
• No YAJI account required.
• Core records stay in YAJI’s private space on your iPhone.
• No advertising or third-party analytics.
• Photos, annotated images, reports, and videos leave YAJI only when you choose to save or share them.
• YAJI does not provide in-app cross-device iCloud sync. Structured app data may still be included in device backups based on your Apple settings, and copies saved to Photos may sync through iCloud Photos.

YAJI PROYAJI Pro unlocks all guided and custom views, advanced comparison tools, reference lines, alignment, progress videos, and complete photo angle annotation.

IMPORTANTYAJI is a personal record-keeping and image-annotation tool. It is not a medical device and does not diagnose conditions, assess treatment outcomes, recommend treatment, or replace care from a dentist or orthodontist.

Photos and angle annotations may vary with lighting, distance, camera settings, lens distortion, angle, and point placement. Do not use them as clinical measurements or proof of treatment results. Do not change appliance wear or treatment based only on YAJI records.

If you experience persistent or severe pain, significant swelling or bleeding, an injury, difficulty breathing or swallowing, or another urgent concern, contact a qualified clinician or local emergency services promptly.
