Caffinity vs Curfew

Caffinity is the caffeine intake monitor that finally tells you when your coffee stops affecting your sleep. Track every cup. Watch your real-time mg level rise and fade. Predict your crash before it hits — and stop drinking past your bedtime. Most coffee tracker apps just count cups. Caffinity uses real caffeine half-life science — your weight, sensitivity, and last dose — to show you exactly how much caffeine is still active in your body, minute by minute. If you've ever lay in bed at 1 AM wondering whether your afternoon cold brew is keeping you up, Caffinity is the app you've been waiting for. ▸ REAL-TIME CAFFEINE INTAKE MONITOR Log any coffee, tea, espresso, latte, energy drink, or soda in two taps.
