Koffee - Caffeine Tracker
Coffee Intake & Sleep Timer
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
Stop guessing when caffeine leaves your body.
Koffee uses a real pharmacokinetic model to show your exact caffeine level in real time — not estimates, not averages. A smooth half-life decay curve tracks every milligram from your morning espresso to your afternoon latte, showing you precisely when you'll be sleep-ready.
WHY KOFFEE
Most caffeine trackers count milligrams. Koffee shows you the science. The half-life curve visualizes how caffeine metabolizes in YOUR body based on your weight, metabolic speed, and lifestyle factors. Optional cortisol bands show the natural rhythm your body follows — so you can time your coffee for maximum effect.
