## Description

See how much caffeine is still in your system, and know when to stop so it won't cost you sleep tonight.

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. Your data syncs across devices via an encrypted, GDPR-compliant database.

DISCLAIMER:
All estimates are based on generalized scientific models and do not constitute medical advice. Consult a healthcare professional for personalized guidance.
