Clear aligner timer
Tap out. Tap in.
It nags you.
That is the entire app, and it is the part every other one started charging for.
Tray 7 of 22 · Day 5 of 10
Go on, press it.
Wearclock is a free aligner wear timer for Android and iPhone. It tracks how long your clear aligners are out against a daily budget, reminds you to put them back in with one tap, counts down to your next tray change, and works offline with no account and no ads.
The rest of it
Four more screens, and that is the whole app. These are screenshots from a running build, not renderings.
The day, hour by hour
Every removal, editable. Swipe a row to fix a time you mistyped, or add one you forgot.
Your tray plan, and what moves
Start a tray late and it shows you exactly which trays shift and what your new finish date is before anything is saved.
One notification. One tap.
It never repeats unless you turn repeat on, and it works with no internet at all.
Numbers your orthodontist can read
Average worn, days at the target, longest single removal. It never rounds a bad month up.
Is the timer free?
Yes, and it stays free. The paywall only appears if you tap a Pro feature — never at launch, never as a popup.

Does it work without internet?
Works on a plane
There is no server to be offline from. The timer, the schedule and every reminder run on the phone.
No sign-in, ever
No account, no email, no password. Nothing to lose and nothing to leak.
One file moves everything
Your whole history exports to a single file you own. New phone, import it, carry on.
Which aligner brands does it work with?
Invisalign®, Spark™, ClearCorrect®, Angel Aligner® — and any tray your orthodontist hands you. Wearclock times a tray. It does not care whose name is on the box, and it never asks.

Free on both stores. The timer is not a trial.
Frequently asked questions
- Does it nag me?
- Yes — when trays have been out past your reminder threshold, Wearclock sends one notification with a single button. Tap it and it's done; it never repeats unless you turn repeat reminders on.
- Is the timer free?
- Yes. The timer, schedule, reminders, log and backup are free forever with no ads. Pro adds extras like widgets, progress photos and PDF reports for $2.99/month, $12.99/year with a 7-day trial, or $19.99 once.
- Does it work without internet?
- Yes. Wearclock runs entirely on your phone with no account and no server, so it works on a plane or anywhere else with no signal. Backups are a single file you control, not a cloud sync.
- Which aligner brands does it work with?
- Wearclock works with Invisalign®, Spark™, ClearCorrect®, Angel Aligner®, and any tray your orthodontist gives you, because the timer only tracks in/out time, not the brand. You set your own tray schedule regardless of which lab made your aligners.
- What does Pro add?
- Pro adds home-screen and lock-screen widgets, progress photos with a ghost overlay to line up each shot, an orthodontist wear report exported as a PDF, and refinement-phase and retainer-mode support. None of it is required for the free timer, schedule and reminders.
