Caffy shows your exact caffeine level right now, and tells you precisely when you'll be ready to sleep tonight. Using pharmacokinetic half-life models backed by FDA, EFSA & NIH research, Caffy calculates your personal caffeine curve based on your biology. WHAT MAKES CAFFY DIFFERENT: • Real-time caffeine decay curve — personalized to your age, gender & sensitivity • Sleep readiness score (0–100) — know if tonight's sleep is at risk before bedtime • Focus window — see exactly when your caffeine peaks for maximum productivity • AI Weekly Analysis — AI reveals your personal caffeine patterns • Caffeine Detox Programs — structured plans to reduce dependence gradually • 6 Live Widgets — caffeine data on your Home Screen and Lock Screen • 5 Languages — English, Turkish, German, Spanish, Japanese PERSONALIZED HALF-LIFE: Your body processes caffeine differently. Caffy accounts for: • Pregnancy (9h / 12h / 18h half-life) • Oral contraceptive use (7h half-life) • Smoking status (3h half-life) • Age, gender & caffeine sensitivity SCIENCE-BACKED: Caffy's model uses the same caffeine decay formula cited by FDA, EFSA, NIH, and the Sleep Foundation — not estimates, not averages. A 45-minute absorption phase followed by exponential decay based on your personal half-life. PRIVACY FIRST: No ads. No data selling. Anonymous by default — no registration required on first launch.
