CaffeineMate: Caffeine Tracker

Love coffee and still want to sleep? CaffeineMate tells you when to stop. Caffeine leaves everyone at a different speed. CaffeineMate estimates your personal caffeine half-life from your weight, age and sensitivity, then turns every drink you log into one live curve: what is in your system now, when it peaks, and how much will be left at bedtime. YOUR LAST CALL Set your bedtime and CaffeineMate works out your Last Call: the latest time for caffeine that still clears before you sleep. Have that afternoon cold brew or skip it, knowing what it means for tonight. SEE CAFFEINE LEAVE YOUR BODY A real-time metabolism curve shows your current level in mg, your peaks and the moment you drop below the level that is friendly to sleep. FORECAST TONIGHT'S SLEEP Connect Apple Health and CaffeineMate compares your caffeine with your sleep. Over time you see how your coffee habits relate to your nights, and get a forecast for tonight. LOG A DRINK IN ONE TAP 46 built-in drinks with caffeine amounts, from espresso and cold brew to tea, matcha, energy drinks and soda. Save favorites, pick serving sizes, create custom drinks, or set up an auto-log for your daily routine. ONE REMINDER, RIGHT ON TIME Get a gentle nudge at your Last Call and a heads-up when you approach your daily limit. Nothing more. SPOT YOUR PATTERNS Weekly and monthly trends, your daily average against your limit, and what your coffee costs if you add prices and a budget. APPLE WATCH AND WIDGETS See your level and quick-add a favorite from your wrist. Home Screen widgets in small, medium and large show your caffeine at a glance.
