    Quantify your cumulative sleep loss over the past week and calculate recovery time.

  • Caffeine Clearance Simulator

    Calculate when that 3PM coffee will actually leave your bloodstream based on a 5-hour half-life.

  • 4-7-8 Breathing Pacer

    Visual metronome for vagus nerve stimulation.

  • Jet Lag Shift Planner

    Calculate when to seek light and when to use melatonin to cross timezones.

  • Melatonin Efficacy Model

    Visualize the threshold where higher melatonin doses actually cause sleep disruption.

  • Chronotype Estimator

    Calculate your natural circadian midpoint based on free-day sleep timing.

  • Thermoregulation Guide

    Calculate the optimal bedroom temperature drop required to trigger sleep onset.

  • REM Suppression Calculator
