A quiet, focused tracker for people on clear aligners who are tired of guessing whether they actually hit today's goal. One tap in. One tap out. 22 Hours handles the rest.


Thinking in "time left out" is easier than counting hours worn. 22 Hours flips the math so staying on track feels obvious instead of stressful.
When your aligners go back in, one tap starts the wear timer. Or just ask Siri.
Your out-time budget bar shows exactly how much longer you can keep them out today.
Hit your daily goal and the streak builds. Drift, and we'll let you know, gently.
The home screen tells you exactly where you stand. The rest of the app stays out of your way until you want it.
How long you've worn today. How much out-time you have left. Whether you're on track or drifting. All visible at a glance.
Hit your daily goal and a streak builds. Miss it, it resets. Honest.
Unlimited progress photos, tagged to each aligner. Saved to your own Photos album.
A compliance ring for every day of your treatment. Tap any day to see and edit individual sessions.
On iPhone and iPad, log sessions hands-free with Siri, even from the lock screen.
Your data lives on your device and syncs through your own iCloud, never ours. No servers on our side, no analytics, no tracking. Clear or export it any time. No ads, ever.
A 14-day chart, your weekly average, longest streak, and goal hit rate. The numbers you actually want, none of the dashboards you don't.

22 Hours started because counting hours worn is the wrong unit. When you only have two hours of out-time a day, you start protecting that budget. Meals fit inside it. Long lunches become a decision, not an accident.
Every detail, the gentle nudges, the streak that resets honestly, the photos saved to your own album is here to make a long treatment feel a little less long. No ads. No upsells. No tracking. Just a quiet tracker that's on your side.
Yes. On iOS, your data lives on your device, and when you're signed into iCloud it syncs to your own private iCloud database, so it's available on your other devices automatically.
On Android, your data lives on your device too. An optional Cloud Backup, off by default, saves a copy to a private, app-specific folder in your own Google Drive that's hidden from other apps and from us.
On every platform, we don't operate a server, we don't run analytics, and we don't have access to your information at any point. Read the full privacy policy.
