A Ring Appstore app

Never leave a door open.

DoorMinder watches your Ring contact sensors. If a door or window is left open past your time limit, you get an email. When it closes, you get another — with how long it was open.

One sensor, a dozen peace-of-mind habits.

Ring contact sensors are tiny and battery-powered, so you can put one on almost anything that opens. DoorMinder turns "did I leave that open?" into an email you actually get.

Front & back doors

Know within minutes if the front door didn't latch or a family member left it wide open on the way out.

Refrigerator & freezer

Catch a fridge or chest-freezer door left ajar before food spoils or frost builds up overnight.

Garage & side gates

Get told when the garage entry door or a backyard gate has been standing open longer than it should.

Medicine & liquor cabinets

Put a sensor on the cabinets you want kept shut, and hear about it the moment one is left open around kids.

Gun safe & storage

A left-open safe or storage locker is a safety issue. DoorMinder flags it fast so you can close it.

Windows before you leave

Heading out or to bed? Know if a bedroom or basement window is still open when it shouldn't be.

Pet & pool gates

Keep pets in and toddlers away from the pool by knowing the instant a safety gate is left unlatched.

Sheds, mailboxes & deliveries

Watch a detached shed, a package drop box, or a workshop and notice if it's been left open all day.

Aging-parent check-ins

Quietly keep an eye on a loved one's exterior door so a door left open overnight doesn't go unnoticed.

Set it once. Get told when it matters.

Link from the Ring app

Install DoorMinder in the Ring Appstore and link your account. Your sensors show up automatically.

Pick a time limit

Choose how long each door can stay open — anywhere from 1 to 60 minutes — right from your dashboard.

Get the two emails

One when a door is left open too long, and one when it finally closes — with how long it was open.

Quietly useful, every single day.

Alerts once, not endlessly

You get one alert per open episode — no repeat nagging while a door stays open.

Closure confirmation

The follow-up email tells you it's shut, so you don't have to go check yourself.

Per-door time limits

A quick trip to the fridge is fine; a garage door open for an hour isn't. Tune each one.

A dashboard that summarizes

See alerts, median and longest open times, and daily activity — not a wall of raw events.
