People spend 5–6 hours a day on their phones (30–40% of their waking life) often mindlessly scrolling. Existing screen time apps focus on reduction, but never answer: to what end? 

Lucid is an iOS app that helps users redirect mindless screen time into activities aligned with their values. During onboarding, you describe your typical day by voice. Claude analyzes it and reveals how you actually spend your time. Then you set a phone usage goal and describe your ideal life. The AI generates a personalized daily template tracking the things that matter to you.

Each morning, Claude helps you plan your day. Throughout the day, a DeviceActivity Monitor tracks your mindless apps, and a Circuit Breaker shield fires when you exceed your goal, reminding you of your own intentions. Each evening, Claude provides CBT-informed coaching based on the gap between intention and reality. Over time, the gap shrinks.

Built entirely with Claude Code in one week!
