NoSnooze – Mission Alarm Clock

Struggle to wake up and love hitting snooze?
NoSnooze is an anti-snooze alarm clock that forces your brain to wake up before the alarm can be dismissed.

Instead of a simple “Stop” button, NoSnooze uses Math Missions and QR Code Missions to make sure you’re truly awake and out of bed.

🔥 Why NoSnooze?

Most alarm apps are easy to dismiss half-asleep. You tap snooze, roll over, and oversleep.

NoSnooze is designed to break that habit by combining:

- Missions that require thinking or moving
- Reliable native Android alarms that survive app kills and battery optimizations
- Fullscreen alarm UI that appears over the lock screen
So you don’t just hear the alarm – you have to interact with it .

🧠 Math Mission – Wake Up Your Brain

- Solve a simple but challenging math problem to stop the alarm.
- Choose difficulty so it matches how hard you are to wake.
- Forces your brain to engage, making it much harder to fall back asleep.
📷 QR Code Mission – Get Out of Bed

- Set a QR code in a specific place (bathroom, kitchen, desk, door, etc.).
- When the alarm rings, you must scan that exact QR code to dismiss it.
- This physically forces you to leave bed and move your body.
Perfect if you keep turning alarms off and going straight back to sleep.

⏰ Reliable Alarm Engine

Under the hood, NoSnooze uses a hybrid architecture :

- Flutter for smooth, modern UI
- Native Android (Kotlin) for:
- AlarmManager with exact alarms
- ForegroundService to keep the alarm running
- Fullscreen intent to show over the lock screen
This helps alarms:

- Keep ringing even if the app was closed
- Better resist battery optimizations on many devices
- Show the alarm screen reliably when it’s time to wake up
🛡️ Fullscreen Alarm Over Lock Screen

- Alarm screen is shown fullscreen , on top of the lock screen.
- Screen turns on so you don’t miss the alarm.
- Harder to ignore than a simple notification.
You see a bold alarm interface instead of a small banner.

🎵 Customizable Alarm Experience

- Choose your alarm sound or use the built-in tone.
- Enable vibration for extra impact.
- Manage multiple alarms for weekdays, weekends, or special days.
- One-time alarms or repeating schedules.
NoSnooze is designed to be simple to use but powerful enough for serious sleepers.

📊 History & Smart Behavior

- Keeps a basic history of triggered alarms so you can track usage.
- Handles one active alarm at a time to avoid conflicts.
- Tries to stay robust even if the system is aggressive with background apps.
🔧 Permissions & Why They’re Needed

To work reliably as an alarm clock, NoSnooze may ask for:

- Exact alarm permission – to ring exactly at the scheduled time.
- Notifications – to show and control the alarm.
- Fullscreen / overlay – to display the full alarm screen over the lock screen or other apps.
- Ignore battery optimization – to reduce the chance of the system killing the alarm.
- Camera – only used for QR Code missions.
All of these are focused on one goal: making sure your alarm actually rings and can’t be dismissed too easily .

🌙 Who is NoSnooze for?

- Chronic snoozers who “just 5 more minutes” themselves into oversleeping.
- Students, professionals, and heavy sleepers who must wake up on time.
- Anyone who wants an alarm that is stronger than their morning laziness .
If regular alarms aren’t enough, NoSnooze gives you the extra push your mornings need.
