The barcode alarm that picks a different item every morning

The appeal of a barcode alarm is simple. A normal alarm dies with one tap from bed; a barcode alarm makes you stand up, walk somewhere and point your camera at a specific code. For heavy sleepers that walk is what actually ends the sleep — far more than a louder sound.

The problem is what happens after a week. With one barcode, the shortcut is obvious: bring the shampoo bottle back to the bedroom, or photograph the barcode and keep the picture by the bed. A half-asleep brain finds that shortcut fast, and the alarm turns back into a one-tap alarm with extra steps.

How the random-item barcode alarm works

Any product barcode or QR code works — cereal, toothpaste, shampoo, coffee, a book, a medicine box. You scan each one once to save it and give it a name, so when the alarm rings it tells you which item to find — the coffee bag, say — rather than showing you a code.

Why one random item beats one fixed barcode

• You can't keep it by the bed. With five items spread across the house, you'd have to keep all five on the nightstand to cheat — at which point you've noticed what you're doing.
• A photo of yesterday's barcode doesn't help. It never picks the same item twice in a row, so last night's screenshot is the one barcode guaranteed not to work.
• No rerolling. Once an alarm has picked its item, closing and reopening the app won't swap it for something closer.
• Searching wakes you up. Remembering where the toothpaste is, walking there, finding the barcode — that's more thinking than a sleepy brain can do on autopilot.

Where to put your items

Spread them out, and keep every one of them out of the bedroom. A good set of five: toothpaste by the bathroom sink, the coffee bag in the kitchen, a cereal box in the cupboard, a book on the hallway shelf, shampoo in the shower. Wherever the alarm sends you, you end up somewhere your morning can start — the sink, the kettle, the front of the house.

If you genuinely can't find the item, there's a way out: switch to the computer code and type the code from wakeupbroo.com/code on a laptop instead. It's not a shortcut — it's the hardest mode in the app.

One of three ways to stop the alarm

The barcode hunt is WakeUpBroo's Medium mode. You choose the mode per alarm:

• Easy: five words appear for ten seconds; type them back in order. Good for lighter sleepers who just need their brain switched on.
• Medium: the random-item barcode hunt on this page. Needs only your iPhone.
• Hard: walk to a laptop or computer and type the rotating code from wakeupbroo.com/code, or scan its QR — more on that in the QR code alarm guide.

None of them has a snooze button. If you slide the iPhone's alarm alert away instead of finishing the task, it rings again a minute later. For the wider comparison with mission alarms like Alarmy, see the best alarm apps for heavy sleepers.
