HOW IT WORKS

Caffeine Tracker uses scientific data to calculate how much caffeine remains in your bloodstream. The extension adjusts calculations based on your profile:

• Half-life varies by sex (4.5-5.5 hours)
• Thresholds adjust to your body weight
• Sleep threshold: 2 mg/kg (when sleep may be affected)
• Maximum threshold: 5.7 mg/kg (recommended daily limit)

PRIVACY

All data stays on your device. Nothing is sent to external servers.

Perfect for coffee lovers, students, developers, and anyone who wants to optimize their caffeine consumption and sleep quality.
