Caffeine Tracker
Read full descriptionHide full description
How much caffeine is actually in your body right now? Coffy answers that with a live half-life curve — not a list of cups you drank and forgot about. WATCH IT LEAVE YOUR SYSTEM Every drink you log is plotted on a real metabolic curve. Coffy shows the milligrams still active in your body at this moment, and tunes the half-life to your own sensitivity: 4, 5 or 7 hours. YOUR CUT-OFF TIME Set your bedtime and Coffy works out the last safe cup of the day — the point after which you would still be above the 50 mg sleep threshold when your head hits the pillow. It also projects how many mg you will have left at bedtime, before you pour the next one. TAPER INSTEAD OF QUITTING COLD TURKEY Pick a starting point and a goal, and Coffy builds a weekly taper plan — around 50 mg less each week — then tracks you against this week's target. Cut back without the headaches. Pause or adjust the pace whenever life gets in the way. NUMBERS YOU CAN ACTUALLY TRUST Caffeine values come from USDA FoodData Central, the FDA and peer-reviewed studies, and every drink shows you its source. Espresso, americano, latte, cappuccino, cortado, macchiato, mocha, matcha, tea, cola and energy drinks are built in — add your own for anything else. WATER TOO Track glasses of water alongside your caffeine, with gentle reminders through the day. HISTORY THAT MEANS SOMETHING Week, month and year views, your daily average, how it compares with the period before, and how many days you went over your limit. Day streaks and badges for days under your limit and nights with no late cup. REMINDERS THAT RESPECT YOUR SLEEP A cut-off alert, water reminders and an evening check-in — each one switchable. APPLE HEALTH & CSV Sync your caffeine intake to Apple Health, and export everything to CSV whenever you want it. Coffy is not trying to make you quit. It is here so you can time it right: full energy when you need it, clean sleep when you want it.
