Why don't my aligner reminders go off?

Wearlo schedules put-back reminders as exact alarms. If one still doesn't ring, check that notifications are allowed, that "Alarms & reminders" is allowed, and that battery optimization isn't restricting the app. Reminders are rescheduled after a restart.

Does the day reset at midnight?

By default, yes, but you can change "My day starts at" in Settings. If you work nights or sleep late, set it to 6 AM, for example, so overnight wear counts as one day.

I forgot to tap. Can I fix it?

Yes. Use "Forgot to tap?" and pick roughly when, like "10 min ago". In History, tap any day to edit, add or delete out times.

Is the widget locked?

No. The widget, the out-timer, reminders and history are all included. The app is supported by a small banner and a few ads between screens.

Can I use it for retainers or a night-only plan?

Yes. Set a night plan of 10–12 hours as your daily goal. It works with any clear aligner or retainer schedule.

Will I lose my data on a new phone?

Not if you back up. Export a backup file in Settings and restore it on the new phone. There is no account; records stay on your phone.

Does it remind me to switch trays?

Yes. Set days per tray and Wearlo reminds you on switch day. Start the next tray in one tap.

Can I show my wear time to my orthodontist?

Share a weekly summary as text. 7- and 30-day average wear times are in History.

How many hours a day should I wear my aligners?

Usually 20 to 22 hours a day. Follow the exact time your orthodontist gives you.

How long can I take aligners out with a 22-hour goal?

24 minus 22 is 2 hours, or 120 minutes, a day. Meals and brushing all count toward it.

Can I track a night-only plan?

Yes. In Wearlo, set a 10–12 hour night plan as your daily goal and it calculates from that.

How many hours a day should you wear clear aligners?

Clear aligners are usually worn 20 to 22 hours a day. With a 22-hour goal, you have exactly 2 hours a day with them out. Always follow the wear time your orthodontist gives you.

Spare time per day by wear goal

Spare time is 24 hours minus your daily goal. Meals, snacks, brushing and cleaning your trays all have to fit inside it.

Daily goal	Spare time per day	Per meal (3 meals)
23 hours	60 min	about 20 min
22 hours	120 min	about 40 min
21 hours	180 min	about 60 min
20 hours	240 min	about 80 min
Night plan 10–12 hours	12–14 hours	-

At 22 hours, three 40-minute meals use up all your spare time. A snack or a coffee comes out of the same budget.

Why spare time disappears so fast

The usual reason is "just a minute" adding up. Put off brushing after a meal, start something else with your trays out, and 20 minutes turns into an hour.

When you estimate, you almost always think you had them out for less time than you did. Logging the moment they come out and go back in is the only accurate way.

Practical ways to hit 22 hours

Set your daily goal and check spare time left today during the day
Tap the timer the moment your aligners come out (a widget means no app to open)
Set the put-back reminder to 30 or 45 minutes to match your meals
Group snacks with meals so you take your trays out less often
Once a week, look at missed days on the calendar and spot the pattern
