About

That afternoon espresso might still be affecting you at midnight. Caffeine has a half-life of about 5 hours, but most people never think about what that means for their body. Mr. Caffeine does the math for you. Log your coffee, tea, or energy drink with a single tap. Mr. Caffeine calculates how much caffeine is still in your system in real time and shows you how it affects your energy, focus, and sleep. HOW IT WORKS Caffeine doesn’t disappear after your last sip. It stays in your system and fades over time. Mr. Caffeine tracks this process using a caffeine half-life model, showing you a clear decay curve throughout the day. You’ll always know where you stand and whether that next cup is worth it. FEATURES · One-tap caffeine logging, espresso, latte, americano, cold brew, energy drinks, and more · Real-time caffeine level, see exactly how much is still in your system · Sleep time estimate, know when your body will be ready for bed · Decay curve, visualize how your caffeine drops hour by hour · Home Screen widgets, check your caffeine level and sleep time without opening the app · Smart notifications, cutoff reminders, daily limit alerts, and sleep warnings · 15 themes, customize the app and widget to match your style · 7 alternate app icons, pick the one that fits your Home Screen · Bedtime and sensitivity settings, personalized to your sleep schedule WHY MR. CAFFEINE Most caffeine trackers give you numbers and charts. Mr. Caffeine gives you a clear answer: can I sleep yet? The interface is simple, two screens, no clutter. Log your drinks, see your status, check the widget. That’s it. Whether you’re trying to improve your sleep, stabilize your energy, or just understand how caffeine affects your day, Mr. Caffeine makes it effortless. Download Mr. Caffeine and stop guessing.
