YAJI vs Aligner Tracker

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.

Aligner Diary keeps your clear-aligner routine organized without requiring an account. RECORD WEAR WITH ONE TAP Mark when you remove or put your aligners back in. Review recorded wear time, correct missed entries, and add a short daily note. FOLLOW EACH TRAY Use the tray-by-tray calendar and daily timeline to see worn, removed, and unrecorded periods. Keep your own change schedule and appointment dates together. BUILD A PRIVATE PHOTO RECORD Take or import photos, keep them with the correct tray and date, browse them by tray, and select multiple photos for a vertical comparison. Photos are records only; the app does not evaluate treatment results. REMINDERS AND WIDGETS Set local reminders for daily confirmation, tray changes, and appointments. Home Screen widgets show your current status and next appointment, with quick wear actions on supported iOS versions. LOCAL-FIRST, WITH OPTIONAL BACKUP Your diary stays on your device by default. Export a complete backup when you choose, or opt in to private iCloud backup for records, photos, and preferences. Private backup is not two-way sync and requires your iCloud account and network access. MAKE IT YOURS Choose from four visual themes, light or dark appearance, and multiple interface languages. Optional one-time tips are available through Apple In-App Purchase. They are not subscriptions and do not unlock features. Aligner Diary is for personal record keeping only. It does not provide diagnosis or treatment advice. Follow the plan given by your dental professional.
