OpenAlarm is the alarm clock for mornings when a normal alarm is too easy to silence. Build alarms around the way you actually wake up: • Require one or more disarm challenges: Math, Memory, Steps, Shake, or Scan • Set a snooze budget so snoozing eventually stops being an option • Enable a wake-up check that asks whether you are still awake a few minutes later • Schedule repeating weekday and weekend alarms • Skip or move one occurrence without changing the repeating schedule • Start nap countdowns and pause or extend them • Control active naps from the Lock Screen and Dynamic Island OpenAlarm uses Apple’s alarm system so scheduled alarms remain dependable. Your alarms and settings stay on your device. There are no accounts, ads, analytics, or tracking. OpenAlarm is free and open source.

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. BarLock rings again a little later to make sure you stayed up. • Backup Alerts. Opened the alarm but never finished the scan? It comes back. • Lock Window. In the minutes before it rings, the alarm can't be edited, paused, or deleted without a scan. 2 a.m. you can't sabotage 7 a.m. you. • Tiptoe Mode. A few quiet seconds after you press Stop, enough to reach your item without waking the house. Miss the scan and the volume comes back. • Stickers. Keep getting up and you'll earn them, in holographic foil. • Alarm sounds built to cut through deep sleep • Everything stays on your phone. No account, no ads, no tracking. WHAT'S INCLUDED One barcode alarm, one sound, and the standard wake-up rules. Enough to fix tomorrow morning. BARLOCK PRO Pro is a one-time purchase. No subscription. • Unlimited alarms for weekdays, naps, travel, and backups • Tiptoe Mode • Your own settings for Lock Window, Backup Alerts, and Wake-Up Check • Your sticker collection, revealed in full holographic color • Every alarm sound in the app PRIVACY Your alarms and scanned codes never leave your device. No account, no advertising, no tracking. Stop snoozing. Scan to stop.
