Caffeine Window helps you understand how caffeine may affect sleep.
Log coffee, tea, energy drinks, cola, espresso, pre-workout, or a custom amount in seconds. See how much caffeine is still active now, when it will mostly clear, and whether another dose is likely to matter before bed.
Features:
• Quick caffeine logging
• Active caffeine estimate
• Clear-by time
• Bedtime-based sleep risk
• Daily timeline and recent trends
• Custom bedtime, wake time, and sensitivity
• Optional local reminder for your caffeine cutoff
Caffeine Window is designed for awareness and planning. It does not provide medical advice.
