22 Hours: Aligner Tracker

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, a 14-day wear chart, your weekday pattern, and your treatment timeline.
• Tap any day to see and edit the individual sessions.

Reminders, not nagging
• Notifications 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 add every switch day to your calendar and keep it 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 gallery - yours to keep even if you uninstall.

Set up in under a minute
• A short onboarding asks about your treatment type, aligner count, switch schedule, and daily wear goal.
• Following a refinement course or a fresh set of trays? 22 Hours follows along and keeps your full history.
• Already a few months in? Backfill past days to reflect your full journey from day one.

Your data is yours
• No ads. No tracking. No analytics.
• Everything stays on your device. There's no server, and we can't see your information.
• Optional private backup to your own Google Drive - restore it when you switch devices, using your own Google account.

Whether you're using Invisalign or another clear aligner system, 22 Hours works for any tray-based orthodontic treatment.

Your wear goal is personal. We'll be with you on your journey to that great smile.
