Most aligner apps count up. OutTime counts down, so you always know exactly how much out-time you have left today. Free to use, with a one-time Pro upgrade and no subscription.

Pro adds the Apple Watch app, Home Screen widgets, full stats history, and more for a single $9.99 purchase. No account, no ads, Family Sharing included. Works with Invisalign, Angel Aligner, Spark, ClearCorrect, Byte, and any other clear aligner. A BUDGET, NOT A STOPWATCH A stopwatch leaves you to do the math. OutTime gives you a daily out-time budget and counts it down every time your aligners come out. Tap once when your aligners come out, tap again when they go back in. SEE WHERE YOUR OUT-TIME GOES Where do your two hours go? OutTime sorts your sessions into Food, Drink, Meetings, and more, with your session count, average, and longest. See your 7-day average next to last week's, and days on budget for every tray. Tap any day in the month calendar to see that day's sessions, or log one you forgot. With Pro, share a clean Wear-Time Summary PDF of any month, plus your session data as CSV, ready for your next appointment. PRO: ON YOUR WRIST AND HOME SCREEN Start and end sessions from your Apple Watch, and see your remaining out-time on your wrist. Home Screen widgets show it all day. While your aligners are out, the countdown also runs on your Lock Screen. FORGOT TO START THE TIMER? Edit any session after the fact: adjust the time or duration, or log a session you missed entirely. Life happens; your data should still be accurate. HANDS-FREE WITH SIRI Hands full at lunch? Say "Take my aligners out with OutTime" to start a session, or "Put my aligners back in with OutTime" to end it. Works with Shortcuts and the Action Button too. YOUR DATA STAYS YOURS No account. No email. No OutTime server. Zero analytics. Zero data collected. Everything lives on your iPhone. Optional iCloud Backup & Restore (Pro) keeps a copy in your own private iCloud so you can restore on a new iPhone, and we still cannot see it. The App Store privacy label says "Data Not Collected." We mean it. SMILE TIMELINE Build a private photo timeline of your smile, tray by tray. Crop, straighten, rotate, and brighten each photo. Put any two side by side and share them, or turn the whole timeline into an MP4 timelapse video. Your first photo is free. Pro unlocks the rest. RETAINER MODE Treatment ends, but retainers do not. Pick "I wear a retainer" on first launch, or switch later. Full-time or nights-only, with a bedtime reminder and replacement reminders on your own schedule. Passive aligners work too.
