Excuse you
Science-backed habit formation. Zero pressure. Complete privacy.
Build lasting habits in 66 days with a conversational companion that uses research-proven methods, not punishment. Your data stays on your device. Your progress, your way.
🧪 Research-Based Science
Built on UCL's groundbreaking 66-day habit formation study. Watch your habit strength grow asymptotically through 4 stages: forming → developing → solidifying → automatic. No pseudoscience, just proven psychology.
📊 Visual Progress Tracking
See your habit automaticity curve in real-time. Track your strength percentage, current stage, and progress toward the automatic threshold. Every day of practice moves you closer to effortless consistency.
🏆 Progressive Milestones
Celebrate meaningful achievements with 12 research-aligned milestones from 3 to 365 days. Each target reflects real psychological transitions, not arbitrary numbers. Build confidence through proven progression.
💬 Conversational Companion
Adaptive conversations that evolve with your journey. Over 25 dynamic sequences respond to your progress, setbacks, and schedule. Feels like talking to a friend who actually understands habit psychology.
🔒 Privacy-First Design
All habit data stays on your device. No cloud sync, no server storage, no tracking your progress for profit. Unlike other habit apps, we can't see your data because we never collect it. Your habits, your business.
🌙 Zero-Pressure Approach
Missed a day? Your habit strength decays gradually, not catastrophically. No streaks destroyed by one bad day. No guilt trips or manipulation. Just honest feedback and encouragement to try again tomorrow.

Why Privacy Matters for Habit Formation
Other habit apps track your every move, sell your data to advertisers, and use your vulnerability against you. We took a different path.
Your habit data lives only on your device. No servers, no cloud sync, no analytics mining your behavior patterns. We designed Excuse You so we literally cannot see your data – even if we wanted to.
Optional crash reporting and performance monitoring use Firebase (Google), but these only collect anonymous technical data. Analytics is disabled by default and requires your explicit opt-in. Everything is disclosed in our privacy policy.
