About

Caffeine Half Life

Features
Read full description

Caffeine Half Life helps you estimate how caffeine leaves your system over time — so you can make more informed choices about sleep and energy. Highlights - Personalized elimination curve using your profile (e.g. smoking, pregnancy, oral contraceptives) when you choose to provide them - Sleep-readiness estimates based on your bedtime and caffeine threshold — approximate only - Apple Health: optional read/write for dietary caffeine, plus HRV correlation on the chart so you can spot patterns (you control permissions) - Widgets and Apple Watch complications for quick glances — including a trend graph complication - Interactive chart — drag to inspect caffeine levels and HRV at any time of day How it works The app uses a simplified pharmacokinetic model (Bateman equation) to estimate caffeine absorption and elimination based on your personalized half-life. Factors like age, BMI, activity level, smoking, pregnancy, and oral contraceptives adjust the half-life up or down from the ~5-hour population average. Important: This app is for general wellness and educational purposes. It is not medical advice and not a medical device. All estimates are approximate — individual metabolism varies.
