YOUR PROGRESS, AT A GLANCE Weekly and monthly wear logs let you see patterns, spot problem days, and stay accountable to your orthodontist's instructions. SIMPLE. PRIVATE. YOURS. No account required.

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.

Verdict
The clearest difference is ads: Retainly at none against TrayTime's shown. Retainly also leads on update cadence (weekly vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
