Build an AI screen time and digital detox coach for people who want their evenings and focus back. 1. Onboarding quiz that identifies the user's top distraction apps, trigger times, and one goal (better sleep, deeper work, less doomscrolling). 2. Manual and semi-automated usage logging: daily self-report of hours per app, optional browser extension that auto-logs web time, and CSV import of the built-in iOS or Android reports. 3. Focus sessions that lock a custom blocklist for a chosen duration, with a single five-minute emergency unlock and a streak counter. 4. AI coach check-ins at set times that ask three quick questions and reply with a tailored nudge, keeping tone supportive and never guilt-based. 5. Trigger detection: AI correlates logged binges with time of day, day of week, and self-tagged moods, then names the pattern in plain language. 6. Ramp-down plans: instead of cold turkey, the coach generates weekly reduction targets for the worst offender apps. 7. Replacement menu: for each blocked session, the app suggests a pre-chosen alternative (walk, book chapter, call a friend). 8. Family or team mode where partners or friends join a shared challenge with opt-in progress sharing. 9. Progress dashboard with reclaimed-hours counter, streaks, and before-and-after patterns. 10. Relapse-friendly design: a slip resets nothing but logs the context so the coach adjusts the plan. 11. Weekly review email with AI-suggested next-week experiments. Never access OS-level app usage without the user explicitly connecting a supported integration, and keep all messaging motivational, not clinical.
