A visual life countdown timer that puts the passage of time into perspective through interactive visualizations.
- Life progress bar — real-time percentage of life elapsed with animated progress track
- Life dot matrix — each square = 1 year, color-coded for lived / current / remaining
- Remaining time cards — years, days, hours, free time, weekends, and meals left
- Time allocation breakdown — shows how remaining years split across sleep, work, phone, chores, and truly free time
- Companion time calculator — estimates remaining visits with parents (and optionally children), with adjustable parameters
- Desk clock mode — fullscreen multi-page clock
- Customizable settings — adjust expected lifespan, daily time allocation, companion parameters via modal dialogs
- Shareable reports — each generated report gets a short unique URL (
?r=abc123) stored in Supabase, shareable as read-only links - Mobile-friendly — responsive design with safe area support
