TrayTime keeps your clear aligner schedule on track. Tap once when your trays go in, tap again when they come out — TrayTime counts every minute toward your daily wear goal. YOUR DAILY WEAR RING See today's wear time at a glance on the 22-hour ring (set your own goal from 20–23 h). When trays are out, a counter shows exactly how long they've been out — meals and brushing stay guilt-free, forgetting doesn't. TRAY CHANGES, ON SCHEDULE Enter your total trays and change interval once. TrayTime shows your current tray, days until the next change, and your estimated finish date — with a reminder on change day. OUT-TOO-LONG REMINDERS Left your trays in the case after lunch? TrayTime nudges you when they've been out too long. You choose the threshold, or turn it off. STREAKS & STATS Hit your daily goal and build a streak. Weekly charts show your wear pattern so you know exactly how your wear routine is going. PROGRESS PHOTOS Keep a private photo diary of your smile, organized by tray, with side-by-side comparison. Photos never leave your phone. WORKS WITH ANY BRAND Any clear aligner brand, any provider. No account, no sign-up, no cloud — everything stays on your device. TRAYTIME PRO (one-time purchase) Remove ads, unlock unlimited progress photos and extended statistics. Pay once, keep it forever. TrayTime is a wear-time tracking tool. It does not provide medical or orthodontic advice — always follow your provider's instructions.
