YoCoffee: Caffeine Tracker

Do you ever wonder why you can't fall asleep — even hours after your last cup of coffee? Caffeine stays in your system far longer than most people realize. YoCoffee helps you understand exactly how much caffeine you've consumed, when it peaks, and when it finally clears — so you can drink what you love and still sleep when you need to. TRACK EVERYTHING IN SECONDS Log coffee, tea, espresso, energy drinks, sodas, and supplements with pre-filled caffeine amounts. Add a drink in under 3 taps. No accounts, no subscriptions — just open and log. KNOW YOUR SAFE ZONE See your running daily total against the 400mg FDA guideline. A clear visual indicator shows you when you're in the green, approaching your limit, or over it. Set a personal limit lower than 400mg if you're caffeine-sensitive. UNDERSTAND YOUR SLEEP WINDOW The caffeine half-life calculator shows a real-time decay curve: how much caffeine is still active in your body right now, and when levels will drop low enough for quality sleep. Stop guessing. See it. SPOT PATTERNS WITH WEEKLY TRENDS Your caffeine intake by day, week, and time of day. See if your Monday headaches are caffeine withdrawal. See if your Friday insomnia comes from that 4pm espresso. CAFFEINE-FREE STREAK TRACKER Trying to cut back? Track consecutive low-caffeine days and build a streak. Get a gentle nudge when you're close to your limit instead of discovering you're over it at midnight. BUILT FOR YOUR BEVERAGES Pre-loaded library covers: espresso, drip coffee, cold brew, Americano, latte, cappuccino, green tea, black tea, matcha, Red Bull, Monster, Bang, Celsius, Diet Coke, and more. Add custom drinks with your own caffeine amount. PRIVACY FIRST All data stays on your device. No account required. No tracking. No ads. Whether you're managing anxiety, improving your sleep quality, reducing caffeine dependence, or just curious about your intake — YoCoffee gives you the clarity to make better choices every day.
