22 Hours: Aligner Tracker
Track your aligner wear time
Free · Designed for iPad
Your aligner journey is hard enough. Now with reminders that fit your style, travel-ready timing, and a guided tour to show you around.
22 Hours is a quiet, focused tracker for people on a clear aligner treatment plan who are tired of guessing whether they actually hit today's goal.
One tap when your aligners go in. One tap when they come out. 22 Hours handles the rest.
The home screen tells you exactly where you stand
• How long you've worn today. How much out-time you have left. Whether you're on track or drifting.
• The daily out-budget bar makes the math simple, thinking in "time left out" is easier than counting hours worn.
Streaks that actually mean something
• Hit your daily goal and a streak builds. Miss it and it resets.
• Your current streak and longest ever, always visible.
Stats and history
• A calendar with a compliance ring for every day of treatment.
• Weekly average, compliance percentage, lifetime hours, 14-day wear chart, weekday pattern, treatment timeline.
• Tap any day to see and edit the individual sessions.
Reminders, not nagging
• The notifications are designed to never make you feel bad about a long lunch or an unexpected meeting.
• Go over your out-budget and you get a heads-up, not a guilt trip.
Switch-day routine
• A reminder the night before each tray switch and a backup the next morning.
• Optionally, every switch day added to your iOS Calendar and kept in sync as your treatment progresses.
Progress photos
• Capture unlimited photos tagged to your current aligner number.
• Bulk import ones you've already taken.
• Everything saved to a 22 Hours album in your Photos library, yours to keep even if you uninstall.
Siri support
• Record a custom phrase to log your aligners in or out without opening the app.
Set up in under a minute
• A short onboarding asks about your treatment type, aligner count, switch schedule, and daily wear goal.
• Already a few months in? Backfill past days to reflect on your full journey from day one.
Your data is yours
• Synced privately across your devices via iCloud.
• Export your full history any time. Restore from backup when you switch devices.
• No ads.
Your wear goal is personal. We will be with you on your journey to that great smile.
