TrayJourney is a calm, simple tracker for clear aligner treatment. Tap when your aligners come out and when they go back in, watch your daily wear time add up toward your goal, and follow your tray schedule from the first tray to the last. Clear aligners work when you wear them enough every day. TrayJourney helps you keep that habit without counting hours in your head. WHAT YOU CAN DO • Wear-time timer: one tap when your aligners come out, one tap when they go back in. Your daily total and goal progress update as you go. • Aligners-out nudge: an optional reminder when your aligners have been out longer than you planned. • Tray schedule: see your current tray, how many are left, and when your next change is due on your provider's schedule. • Progress photos: take photos as you move through your trays and look back at how your smile has changed. • Tray history and insights: review past trays and how consistently you wore each one. • Appointments and care team: keep your next check-up date and your provider's details in one place. WORKS WITH ANY CLEAR ALIGNER TrayJourney is independent and works with aligners from a dentist, an orthodontist, or an at-home service. It is a tracking companion, not medical advice. Always follow your provider's instructions. JOURNEY PRO TrayJourney is free to download. Ongoing wear tracking, tray history, progress photos and the aligners-out nudge are part of Journey Pro, available monthly, yearly, or as a one-time lifetime purchase.

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.
