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.
