Koffee vs PauseCafé

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.
