// QR CODE ALARM
A QR code alarm app that's actually hard to cheat
Scan-to-dismiss alarms are a great idea: make the off switch a code you have to walk to. WakeUpBroo takes the concept further by putting a rotating code and QR on this website — on a separate device — so there's nothing by your bed to scan and go back to sleep.
The whole point of a QR or barcode alarm is to force movement. A normal alarm dies with one tap; a scan alarm makes you get up and point your camera at a specific code before it stops. For heavy sleepers, that physical step is far more effective than a louder buzzer.
But the classic version has a weak spot. If the code is a sticker you printed and taped to the bathroom mirror, nothing stops you from photographing it once and keeping the photo by your bed — scanning it without ever standing up. The dismiss is only as strong as where the code lives.
How WakeUpBroo's scan dismiss works
WakeUpBroo shows the dismiss code and QR on wakeupbroo.com/code instead of on a printed sticker. Two things make that harder to game:
- It rotates on a short cycle. A screenshot from earlier won't work, so you can't cache the code by your bed.
- It lives on another screen. Open it on a laptop or spare device across the room and you have to go there to read or scan it.
Open the code on another device
When the alarm rings, open wakeupbroo.com/code on a laptop, PC, or spare phone you left across the room.
Scan the QR — or type the code
Point the app at the on-screen QR, or read the rotating numeric code and type it in. Either works.
The alarm stops — and you're up
By the time you've walked over and scanned, you're awake. The code rotates, so yesterday's screenshot won't help.
Prefer not to scan? You don't have to. The same page shows a short numeric code you can type into the app — useful if your camera is slow to focus first thing in the morning. Both routes require getting to the other device, which is the part that wakes you.
Why a second device makes it stronger
The reason heavy sleepers dismiss alarms without waking is that the off button is right there, reachable on autopilot — see why you turn off alarms in your sleep. Moving the code to a device across the room removes that reflex entirely. There's no button on your phone to press, and no sticker within arm's reach to scan. You have to stand up, walk over, and engage your eyes and hands — by which point you're genuinely awake.
It pairs naturally with a no-snooze design: no snooze to delay it, no dismiss button to tap, and a scan or code that only exists somewhere you have to walk to.

Frequently asked questions
What is a QR code alarm app?
A QR code alarm app is an alarm that won't turn off until you scan a specific QR or barcode. The idea is to place the code somewhere away from bed — like the bathroom or kitchen — so you have to get up and walk to it to stop the alarm.
How does WakeUpBroo's QR code dismiss work?
Instead of a sticker you print and tape to a wall, WakeUpBroo shows a rotating code and QR on wakeupbroo.com/code. When the alarm rings, you open that page on a laptop or another device away from bed and either scan the QR or type the code into the app. Because the code rotates and lives online, it can't be photographed once and reused.
Is a QR code alarm better than a barcode alarm?
They work on the same principle — scan something to dismiss. The bigger factor is where the code lives. A printed barcode or QR can be photographed or kept by the bed, which defeats the point. A rotating code on a website you open on a second device is harder to cheat.
What if the QR code won't scan?
Make sure the website code page is open and bright, your iPhone camera permission is enabled for WakeUpBroo, and you're close enough. If scanning still fails, you can always enter the rotating numeric code manually.
