I built BedtimeCalc for people who want a direct sleep timing answer without digging through long articles. It helps plan bedtimes, wake-up times, naps, shift schedules and age-based sleep windows using practical cycle-based recommendations. Feedback on which real-life schedules should be added next would be very useful.
