Why AlignDay

Aligner treatment succeeds or fails in those 20 hours a day

01

Honest timekeeping

Aligner wear time comes from real timestamps, not a foreground timer — quitting the app or restarting your phone loses nothing. Cross-midnight sessions split per day, and back-filled entries are overlap-protected. The ledger holds up.

02

Consistency you can see

Calendar goal rings, trend charts, per-tray statistics. See at a glance how your aligner wear is really going — and show your orthodontist actual data instead of "pretty good, I think."

03

Private by default

No account, no server, no analytics SDKs. Your aligner records and photos live only on your phone — we could not see them if we wanted to.

How it works

Three taps a day, roughly

01

Set up your tray plan

Tell AlignDay your current tray number, days per tray, and daily wear goal — the defaults follow the common 20-hour prescription.

02

Tap when aligners come out

One tap starts the out-timer and shows your remaining out-time budget. Put your aligners back in, tap again — the session lands in today's ledger.

03

Watch progress build

Calendar rings fill day by day, statistics accumulate per tray, and switch-day reminders keep the plan moving.

Who it is for

If you are wearing clear aligners

Just getting started

The first few trays are habit-forming weeks. The timer and reminders turn "wear it 20 hours" from advice into routine.

A few trays in

Mid-treatment is where discipline slips. The daily out-time budget and overrun alerts keep every "I will put it back in a minute" accounted for.

Facing check-up questions

When your orthodontist asks how wear has been going, open the stats page. Real data beats memory.

Features

Everything an aligner tracker should do — and nothing else

Six things, all in service of wear time. No community, no points, no feed.

Aligner wear timer

The home screen is a progress ring: how long your aligners have been in today and how far to goal, readable in one glance. Take out and put back are each a single tap.

Out-time budget

Three lenses — 7 days, 30 days, per tray — with goal rates, trend lines, and consistency. Your discipline deserves to be visible.

FAQ

Aligner tracking questions, answered

What is an aligner tracker?

An aligner tracker is an app that records how many hours a day you actually wear your clear aligners, so you can compare real wear time against the 20–22 hours most orthodontists prescribe. AlignDay does this with one-tap logging, automatic per-day statistics, and switch-day reminders — with every record stored on your iPhone.

How many hours a day should I wear clear aligners?

The common clinical guidance is 20–22 hours a day (see the American Association of Orthodontists) — always follow your own orthodontist's instructions. AlignDay defaults to a 20-hour goal, adjustable in Settings.

Is the timer still accurate if I quit the app or restart my phone?

Yes. AlignDay records the timestamps of take-out and put-back; wear time is computed from those timestamps and does not depend on the app staying open. Cross-midnight sessions are split per calendar day so statistics stay clean.

Is my data safe? Where is it uploaded?

Nowhere. All data lives locally on your iPhone. AlignDay has no accounts, no servers, and no analytics SDKs, and transmits nothing to us or to third parties. See the Privacy Policy for details.

What if I forget to tap take-out or put-back?

You can back-fill wear intervals for any time range on the History page. Back-filled entries are overlap-protected, so the ledger always stays consistent.

Which aligner brands does it work with?

Any removable clear aligner — Invisalign, ClearCorrect, Spark, Angel Aligner, or any other brand. AlignDay tracks wearing behavior itself; it is brand-agnostic and never requires linking a provider or treatment plan.

How is AlignDay different from brand apps like My Invisalign?

Official brand apps are companions to one treatment system and typically involve accounts and data collection. AlignDay is an independent aligner tracker: it works with any removable aligner brand, needs no account, and keeps every record on your iPhone. If what you want is honest wear tracking, that focus is the point.

Does AlignDay work offline?

Fully. Tracking, history, statistics, photos, and reminders all run on-device with no server behind them — an internet connection is never required.

Can I use AlignDay for retainers too?

Yes. If you are in the retainer phase and your orthodontist wants a set number of wear hours per day or night, the same timer, history, and reminders work unchanged — set your own daily goal and track retainer wear exactly like aligner wear.

Does AlignDay cost anything?

All current features are free to use, with no ads. Optional premium features may come later — but your data will always be yours.

From our co-founder

Why AlignDay exists

I have practiced orthodontics for more than fifteen years. The hard part of clear-aligner treatment is rarely the aligners themselves — it is whether they are actually worn, twenty hours a day, for months on end. Almost none of my patients could tell me that accurately. Not because they lied: because nobody can reconstruct a full day of take-outs and put-backs from memory.

What made me act was an argument in my clinic. A seventeen-year-old's teeth had stopped tracking for two consecutive check-ups. Her mother was certain she wasn't wearing her aligners; she insisted she wore them more than twenty hours a day. The scattered alarms and notes on her phone finally told the real story — the aligners came out after school every day and went back in two or three hours later. Neither of them was lying. They simply had no record.

We have precise scanners and sophisticated planning software, yet no quiet, reliable tool for the most basic behavior in the entire treatment. AlignDay began as a two-button timer for my own patients. Their requests — reminders, back-filling, an out-time budget, records to show at check-ups, no gamification, no data sold to anyone — became the app.
