Aligner & Retainer Wear Timer

Aligner Timer keeps count of the hours your clear aligners are in, so you hit the 22 hours a day your orthodontist asked for. Tap when the trays come out, tap when they go back in. The app watches the clock so you don't have to.

Works with Invisalign, ClearCorrect, Spark, Angel and any other clear aligner or retainer.

ONE TAP, ANYWHERE
Trays in or out from the app, from the home-screen widget, or straight from the notification. The widget is free and stays free.

COUNTS DOWN, NOT UP
Twenty-two hours a day leaves two hours for eating and brushing. Aligner Timer shows how much of that out-time is left today, live, and turns red when you're past it. No mental arithmetic.

REMINDERS THAT ACTUALLY REMIND
Real notifications, not silent pop-ups: after 30 minutes out, again at 45 and 60, then every 30 until the trays are back in. A warning at 20 minutes of out-time left, and another when it runs out. All of it adjustable, with quiet hours if you want them.

TRAY CHANGE SCHEDULE
Tray 7 of 24, change on Monday evening. A reminder the evening of the last day, with Changed and Tomorrow buttons. Add a day when your orthodontist says so. See the projected schedule and an estimated finish date. Refinements? Start a new set and keep the history.

HOW YOU'RE DOING
Hours worn per day, days on target, your current streak, and the average wear on each tray you've finished. Forgot to tap? Fix the times in a few seconds. Had a short day? The app suggests an extra day on the tray; you decide.

AFTER TREATMENT
Retainer mode switches to night-only wear: a nightly reminder to put the retainer in and a target of hours per night.

EXTRAS
Optional reminders for chewies after the trays go in, for changing elastics, and for your next appointment. Back up everything to a file and restore it on a new phone.

WHAT IT DELIBERATELY DOES NOT DO
- No account, no login, no email
- No cloud, no sync, no servers
- No ads
- No analytics, no crash reporting, no tracking of any kind
Everything stays in the app's private storage on your phone.

ALIGNER TIMER PRO
The timer, the widget, the reminders and backups are free. A one-time purchase unlocks full history, patterns (when your trays come out, your longest out sessions), the per-tray report and CSV export. One payment. Yours forever. No subscription.

Aligner Timer records what you do. It is not a medical device and does not give treatment advice; follow your orthodontist's instructions.
