Store description excerpt
Stop guessing if it’s too late for coffee. Know the answer. Most trackers just count cups. Caffeine Curfew models the biological half-life of every milligram you drink to predict exactly when your body will be ready for sleep. Caffeine doesn’t disappear when you finish your drink. It decays slowly over 5–8 hours. A 4 PM espresso can leave you chemically awake at midnight. Caffeine Curfew reveals this hidden "active caffeine" level so you can protect your sleep quality, avoid insomnia, and wake up rested. MEET LEO: YOUR AI SLEEP STRATEGIST Powered by Apple Intelligence (on supported devices), Leo is your witty, data driven sleep coach. He doesn't just show you numbers; he gives you the brutal truth about your habits. • "You're over budget." • "One more espresso will ruin your deep sleep." • "You're clear for takeoff." Leo analyzes your intake against your custom bedtime to give you a personalized "Safe" or "Critical" status instantly. SCIENCE BACKED FEATURES • Real-Time Half-Life Decay: Watch your active caffeine levels drop in real time. • Sleep Risk Analysis: Know your projected bedtime status before you take that first sip. • Custom Physiology: Adjust your personal metabolism rate (half-life) and sensitivity threshold. • Smart Pre Sets: Log generic drinks or scan barcodes with a tap. BUILT FOR THE APPLE ECOSYSTEM • Live Activities & Widgets: Monitor your decay right from your Lock Screen or Dynamic Island. • Apple Watch App: Log drinks and check your "Active Mg" from your wrist. • Siri & Shortcuts: "Hey Siri, log an espresso." • Apple Health Sync: Seamlessly reads your sleep data to fine tune your nightly curfew. WHY CAFFEINE CURFEW? Whether you are an athlete optimizing recovery, a student pulling all nighters, or just someone tired of staring at the ceiling, clarity is the cure. This isn’t just a timer; it’s a biological fuel gauge for your brain. Download Caffeine Curfew and master your energy today.
