Track your caffeine and sleep better. See exactly when today's coffee wears off. Caffeine Clock is a caffeine tracker that models absorption and half-life to estimate how much caffeine is in your system throughout the day. Log what you drink or eat, see how levels rise and fall, and plan your last cup so you can sleep with confidence. Accurate tracking with absorption rate Not just totals. Caffeine Clock models how quickly you absorb caffeine and how it declines (half-life), then estimates your level now and later. If you note how long you sipped that cappuccino, the curve updates accordingly. A clear, actionable dashboard An attractive graph shows your current level, projected decline, and how much caffeine you'll have at any time. Long-press to scrub the timeline and reveal exact values. At a glance, know whether you're in the clear - or whether another cup will push you past your comfort zone. Interactive Home Screen Widgets Monitor your stats without even opening the app. View your live caffeine curve and current mg count directly on your Home Screen. Need to log a refill? Use the quick-add widget to track your favorites with a single tap - keeping your data accurate with zero friction. Sleep-aware insights Set a target bedtime. If your projected level looks high by then, Caffeine Clock lets you know early, often before you even add a drink, so you can adjust your cut-off and protect tonight's sleep. Tuned to you A quick setup captures your habits and sensitivity, and you can adjust your personal caffeine half-life at any time in Settings, so the curve matches how your body actually clears caffeine. 200+ drinks, plus your own Choose from a built-in database of coffees, teas, and energy drinks, or create custom drinks with your own sizes and mg. Fast logging means better tracking. Thresholds and gentle alerts Pick a daily caffeine limit that fits your routine, whether that is the commonly cited 400 mg for adults or the 200 mg guideline many people follow during pregnancy. Get timely reminders before you overdo it. Apple Health Send every logged drink to Apple Health so your caffeine sits next to your sleep and the rest of your health data. Private and fully offline No account, no signup. Your data stays on your device, with an option to transfer locally. Caffeine Clock works fully offline. Anytime, anywhere. Made for everyday routines Whether it's espresso at 8, tea at 2, or an energy drink before a workout, Caffeine Clock shows how today's choices affect tonight's sleep, so you can enjoy what you love without second-guessing it. How it works - Log a drink from the 200+ library or use the quick-add widget. - The app models absorption and half-life to estimate your level over time. - Watch the live caffeine curve and countdown on the dashboard or Home Screen. - Set a bedtime and get informed if you may still be "too caffeinated" by then. Why a dedicated caffeine tracker? Caffeine affects everyone differently. A general health app won't tell you when a 3 PM latte will still be in your system at 10 PM. Caffeine Clock focuses on one job: timing your intake for better days and better nights. Get started in minutes Install, finish the onboarding, log your first drink, and watch your caffeine curve come to life.
