How it works

A few taps a day. That's it.

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.

STEP 01

Tap in.

When your aligners go back in, one tap starts the wear timer. Or just ask Siri.

STEP 02

Track your time.

Your out-time budget bar shows exactly how much longer you can keep them out today.

STEP 03

Build your streak.

Hit your daily goal and the streak builds. Drift, and we'll let you know, gently.

Features

Everything you need. Nothing you don't.

The home screen tells you exactly where you stand. The rest of the app stays out of your way until you want it.

The math, handled.

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.

About

Built by someone who wore them too.

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.

- Your journey to that great smile. We got you.
Frequently asked

Questions, answered.

Does 22 Hours work with Invisalign, Spark, and other clear aligner brands?
Yes. 22 Hours works with any clear aligner treatment. Invisalign, Spark, ClearCorrect, Byte, in-house lab trays, retainers. During setup you tell us your tray count and switch schedule and the app adapts to that.
What if I just started. Can I backfill past days?
Yes. The onboarding lets you backfill sessions for past days so your streak, calendar, and stats reflect your full journey from day one.
Is my data private?

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.

Photos are saved to a "22 Hours" album in your Photos library. They stay there even if you uninstall the app. You can bulk-import existing photos and tag them to specific aligners.
Does it nag me when I'm out for too long?
No. Notifications are designed to never make you feel bad about a long lunch or an unexpected meeting. If you go over your out-time budget, you get a heads-up, not a guilt trip.
