BarcodeWake: Mission Alarm

BarcodeWake is a mission alarm clock for heavy sleepers. The alarm stops only when you complete a mission: scan a barcode or QR code, solve a math problem, type a sentence, shake your phone, walk real steps, or tap an NFC tag. No snoozing from bed, no cheating, no ads, no subscription. 100% free, 100% offline.

WHAT IS A MISSION ALARM CLOCK?
An alarm you cannot swipe away. You must prove you are awake. Register a barcode on something far from your bed (toothpaste, cereal box, a QR code on the fridge) and the alarm keeps ringing until you get up and scan it.

6 MISSIONS TO PROVE YOU ARE UP
★ SCAN TO DISMISS — scan your registered barcode or QR code (EAN, UPC, Code128, Code39, QR). Any product in your home works.
★ MATH — easy, medium or hard problems.
★ TYPING — type a sentence exactly.
★ SHAKE — shake your phone until the counter is full.
★ WALK — take real steps, counted by the pedometer.
★ NFC — tap an NFC tag in the bathroom or kitchen.
Chain up to 5 missions in one alarm, or let the app pick a random one.

WAKE UP CHECK
Dismissed the alarm and crawled back into bed? A few minutes later BarcodeWake checks that you are still awake. If not, the alarm rings again. The wake up check is free, not a paid add-on.

ANTI-CHEAT PROTECTION
✓ Volume buttons, notification shade and back button blocked while ringing
✓ Watchdog re-launches the alarm if the app is killed
✓ Survives reboot and force-stop
✓ Optional power-off menu block while ringing
✓ Emergency exit you control: 30-second silence and a PIN-protected emergency dismiss, once per 24 hours

WHY DOES MY ALARM NOT RING?
On many phones the battery optimizer silently kills alarm apps. The built-in Reliability Doctor detects your manufacturer (Samsung, Xiaomi, Oppo, OnePlus, Huawei) and shows the exact settings to change, then gives you a reliability score.

FOR HEAVY SLEEPERS AND SHIFT WORKERS
• Shift repeat: every N days from a date, one-off date alarms, or weekdays
• Next alarm widget with one-tap Skip next
• Bedtime reminder and 20/30/45-minute nap timer
• Gradual volume per alarm
• Custom alarm sound from any audio file, or random tone rotation
• Extra loud: remastered tones, 6 maximum-loudness tones (klaxon, siren, air horn, red alert, evacuation, smoke detector) and a loudness booster

TRAVELING? ONLY-AT-HOME MODE
Away from your registered code? The scan mission switches to a math challenge, so you are never stuck in a hotel without your barcode.

BACKUP AND SAFETY
Printable PDF backup codes if the camera fails, auto-torch for scanning in the dark, and a quiet "try mission" preview before bedtime.

IS IT REALLY FREE?
Yes. No ads, no paywall, no subscription, no premium tier. Everything unlocked from day one.

PRIVACY FIRST
No account, no internet, no tracking. Barcodes are stored only as hashes on your device. Data safety: no data collected.

ACCESSIBILITY SERVICE (OPTIONAL)
BarcodeWake uses the AccessibilityService API only for the optional "Block power-off while ringing" feature: while an alarm is ringing, it closes the power-off menu so the alarm can't be silenced by turning the phone off. It is off by default, you turn it on yourself in Android Accessibility settings, and you can turn it off at any time. It never reads screen content and collects or shares no data.

WHO IS IT FOR?
Heavy sleepers, chronic snoozers, students, nurses and shift workers, and anyone whose "5 more minutes" turns into 45.

Get BarcodeWake. Get up. No excuses.

Recent changes:
Improved consent for the optional power-off menu protection: choose whether to allow it before opening Android Accessibility settings. Fixed stale permission status and cancellation of pending power-menu actions after ringing ends.
