About

Aligner Diary

Features
Read full description

Aligner Diary is a private personal tracker designed to make clear-aligner routines easier to follow and treatment progress easier to review. WEAR TIME AT A GLANCE Record when your aligners go in or come out. The app totals today’s wear and time-out periods and shows how much time remains within your daily goal. 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. CHECK-INS AND TRENDS Log soreness, fit, attachment concerns, aligner damage, sharp edges and gum bleeding. Trend views help you organize recent observations and decide what to discuss with your dentist or orthodontist. CALENDAR AND EDITABLE HISTORY Use the calendar to review daily wear, photos and check-ins. Edit or delete entries whenever something was recorded incorrectly. REMINDERS, THEMES AND TWO LANGUAGES Use optional wear and tray-change reminders, choose from multiple interface themes, and switch between Simplified Chinese and English. ALIGNER DIARY PRO Optional Pro access adds dentist-ready PDFs, shareable photo comparison cards, advanced reminders and a device privacy lock. Choose monthly, annual or lifetime access and restore eligible Apple purchases. ACCOUNT, PRIVACY AND LOCAL DATA Core aligner records and teeth photos stay on your device. No registration is required to buy or restore Pro through Apple. An optional account can sync membership entitlement; any account can be permanently deleted in the app. Export, preview and restore local backups at any time. Aligner Diary is for personal tracking only. It does not provide medical diagnosis, treatment advice or emergency services. Contact a dentist or orthodontist about persistent pain, damaged aligners, poor fit or other health concerns.
