## What is Unbreakable?

For everyone who says "this time I'll do it" and never follows through.

Unbreakable is a revolutionary accountability app that uses a real-life "witness" to make your commitments truly unbreakable.

HOW IT WORKS

1. Declare your commitment (e.g., "Study 30 minutes every day")
2. Hand your phone to a trusted witness who sets a secret 4-digit PIN
3. Every day, your witness enters the PIN to confirm your check-in
4. You never know the PIN — there's no way to cheat

THE SOCIAL PRESSURE ENGINE

If your witness rejects your check-in, a failure report is shared to your social media (X, Instagram, etc.). The fear of public accountability becomes your strongest motivator.

KEY FEATURES

- Two goal types: Achieve something new / Quit a bad habit
- Categories: Study, Exercise, SNS, Gambling, Alcohol, Custom
- Flexible scheduling: Deadline goals or daily/weekly habits
- Streak calendar: Visualize your consecutive success days
- Daily reminders: Never forget to check in
- Progress sharing: Share your achievements on social media
- 100% local data: Your information never leaves your device

PERFECT FOR

- Quitting alcohol, smoking, or social media addiction
- Building study or exercise habits
- Anyone who's tired of being a serial quitter
- Goals you can't achieve alone

PRIVACY FIRST

All data is stored locally on your device. No external servers, no analytics, no ads. Your commitments are your business.

Make your commitment. There's no turning back.
