About Caffeine Half-Life Tracker – Sleep-Friendly Coffee Timing

Caffeine Half-Life Tracker is a focused, independent web utility at caffeine-half-life-tracker.hub2.day that helps you visualize when your last coffee, tea, or energy drink may stop interfering with your sleep.

What This Site Does

You tell the tool when you consumed caffeine, how much you had, and how sensitive you are to its effects. The tracker then plots a personalized decay curve so you can see the estimated window during which caffeine might still be active in your system. It is designed for coffee drinkers, shift workers, insomniacs, and anyone who wants to make more informed choices about their evening cup.

Why It Exists

Caffeine's half-life varies widely from person to person, yet most generic advice ignores individual differences. This site gives you a simple, visual way to explore your own timing without downloading an app or creating an account. Everything runs in your browser, and no personal data is collected from the tool itself.
