Caffeine Half-Life Calculator - Track caffeine decay in your body instantly

A caffeine calculator that goes beyond total intake. It shows how caffeine decays in your body over time using real half-life science. Track multiple drinks, see overlapping effects, and check if your levels will impact sleep. Fast, accurate, no login required — built for coffee lovers, students, and anyone wanting clearer insight into their daily caffeine habits.

Hey everyone! Super excited to share the Caffeine Half-Life Calculator with you all! I built this tool because caffeine affects everyone differently, and most people have no idea how long it actually stays in their system. This calculator shows you how much caffeine is still in your body over time, based on real half-life science — super useful for avoiding late-night jitters, planning your coffee intake, or managing sleep. I’d love to hear what you think, how accurate it feels for you, and what features you'd like me to add next. More tools are coming soon under the Caffeine Compass umbrella, so feedback right now really helps shape what I build next. 🙌 Thanks so much for checking it out — I appreciate every comment and suggestion! ☕💛
