Description
Caffeine Tracker: Caffi helps you understand exactly how caffeine affects your body, your energy, and your sleep.
Most people drink coffee on autopilot. Caffi changes that. Log every cup, shot, or energy drink in seconds and watch your personal caffeine curve come to life. See how long your last espresso will keep you wired, when your focus will peak, and the exact moment caffeine stops protecting your sleep.
This caffeine tracker is built around your biology, not averages. Caffi calculates your personal half-life based on your habits, age, and weight, then predicts your sleep cliff so you know your last safe drink time every single day.
