Other aligner apps count up. OutTime counts down — so you always know exactly how much out-time you have left today. OutTime is a personal timer and does not provide medical advice. Always follow your orthodontist's instructions. No account. No OutTime server. No subscription. Your data stays yours. OutTime Pro is a single $9.99 purchase — yours for your whole treatment and retainer life after. Works with Invisalign, Angel Aligner, Spark, ClearCorrect, Byte, and any other clear aligner. Free: countdown timer, activity tags, break-type stats, tray calendar, reminders, Siri. Pro ($9.99 once): Apple Watch, Lock Screen countdown, smile timelapse, Wear-Time Summary, and more. A BUDGET, NOT A STOPWATCH Most aligner trackers count up your wear time and leave you to do the math. OutTime gives you a daily out-time budget and counts it down every time your aligners come out. No math. No guessing. 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 actually 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, your streak and best ever, and days on budget and average out-time for every tray. Tap any day in the month calendar to see that day's sessions, or log one you forgot. With Pro, turn any month into a Wear-Time Summary — a clean, shareable summary of your logged sessions, ready to show at your next appointment. 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 the Shortcuts app and the Action Button too. 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. YOUR DATA STAYS YOURS. PERIOD. No account. No email. No OutTime server. Zero analytics. Zero data collected. Everything lives on your iPhone — or, with optional iCloud Sync (Pro), in your own private iCloud, which we still cannot see. The App Store privacy label says "Data Not Collected." We mean it. ON YOUR WRIST, LOCK SCREEN, AND HOME SCREEN Start and end sessions from your Apple Watch, and see the countdown on your watch face, on your Lock Screen (Live Activities), or in a Home Screen widget. SMILE TIMELINE Build a photo timeline of your smile, tray by tray. Photos are wide to fit your whole smile; crop, straighten, rotate, and brighten them. 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. Photos live only on your device; we can't see them. RETAINER MODE Treatment ends, but retainers do not. Switch to retainer mode for nights-only tracking with its own schedule and reminders. OUTTIME PRO — $9.99 ONCE - Smile Timeline — unlimited photos, side-by-side sharing, save to Photos, MP4 timelapse - Wear-Time Summary — a clean, shareable recap of any month - Full stats history — every month and every tray, back to day one - Live Activities — your countdown on the Lock Screen and Dynamic Island - Apple Watch app & complications - iCloud Sync — back up to your own private iCloud and restore on a new iPhone - Home Screen widgets - Alternate app icons — six looks for a quieter Home Screen - Cleaning & appointment reminders - CSV data export FREE FOREVER - Full countdown timer with daily budget - Activity tagging (Food, Drink, Meeting, Brush, Exercise, Other) - Break Types stats — see where your out-time goes - 7-day average, streaks, and current + previous tray stats - Month calendar with day-by-day session details - Hands-free Siri voice commands - Tray calendar — extend, delay, and set the days for each tray - Out-time and tray change reminders - Your first Smile Timeline photo For informational purposes only.
