The alarm rings, you swipe it away half asleep, and you wake up late again. SmartClock stops that: the sound only turns off after you finish a mission. MISSIONS THAT ACTUALLY WAKE YOU UP - Math: solve equations before the ringer stops. - Memory: repeat the pattern the screen shows you. - Shake: move the phone until the counter hits zero. - Squat: get out of bed and complete the reps. - Barcode or QR: scan a code you left in the kitchen. - Photo: take a picture of a spot far from your pillow. BUILT FOR HEAVY SLEEPERS Loud, escalating alarm sound that keeps rising until the mission is done. No snooze mode for people who oversleep every single morning. Repeat schedules for shift work, early flights and gym days. Difficulty levels so the challenge matches how deep you sleep. HOW IT WORKS 1. Pick a time and the days it repeats. 2. Choose the mission and how many rounds you must clear. 3. In the morning, finish the mission and the alarm stops. PREMIUM SmartClock Premium is an optional subscription that unlocks the premium features listed in the app. Terms are shown before you confirm. Set your first mission alarm tonight and stop fighting the snooze button. EULA: https://applu.me/smart-clock/eula Privacy Policy: https://applu.me/smart-clock/privacy-policy

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.
