You don't have a waking-up problem. You have a turning-off-the-alarm problem. BarLock keeps ringing until you get up and scan a barcode across the room. No snooze. No negotiating. Pick an alarm time, scan a barcode or QR code on something that lives away from your bed, and that exact code becomes the only way to stop the alarm. Toothpaste, coffee, medication, a notebook. Anything that forces you to stand up. HOW IT WORKS 1. Create an alarm. 2. Scan a barcode or QR code on an item away from bed. 3. Name the item. 4. When the alarm fires, walk to the item and scan it. 5. Wrong item, wrong code, or no scan? The alarm keeps ringing. WHY IT WORKS Most alarms die from one tap while you are still half asleep. BarLock moves the off switch across the room. By the time you have scanned, you are on your feet, and getting on your feet is the whole battle. BUILT FOR • Heavy sleepers • Students with early classes • Shift workers • Serial snoozers • Anyone who turns off alarms without remembering it WHAT YOU GET • An alarm only your chosen barcode or QR code can stop • A full-screen Scan to Stop screen the moment it rings • Wake-Up Check.
