Caffeine Tracker vs Caffeine Tracker

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.

Coffee is fine. Coffee at the wrong hour isn't. Sundown works out the last moment you can still have your usual drink and sleep — then shows you what happens if you have one anyway. AN ANSWER, NOT A NUMBER Every other tracker opens on a total. Sundown opens on a sentence: "Last drip coffee by 2:10 PM." The screen is a sky, and the sun sitting on the curve is the caffeine in you right now. The lower it hangs, the closer the day is to done. SEE IT BEFORE YOU DRINK IT Pick a drink, drag the time, and watch tonight change in front of you. A cold brew at 4pm and a cold brew at 6pm are not the same night, and now you can tell which is which. YOUR BODY, NOT AN AVERAGE People clear caffeine at wildly different speeds — the same cup can wear off in three hours or hang around for ten. Smoking roughly halves it. Hormonal contraceptives roughly double it. Set yours in three taps, or by hand. REAL PHARMACOKINETICS Caffeine peaks about an hour after you drink it, not the instant you log it. Sundown models absorption and elimination properly, including the slow-release kind in pre-workout. EVERYTHING THAT HAS CAFFEINE IN IT Drip, pour over, French press, AeroPress, Moka pot, K-Cup, instant, cold brew, nitro, espresso drinks. Black, green, white and oolong tea, matcha, yerba mate, chai. Energy drinks and soda. Plus the caffeine in dark chocolate, in painkillers, and in caffeine pills and gum. Make your own for anything missing. COME DOWN WITHOUT THE HEADACHE Cutting caffeine fast is what causes the headache. Taper plans step you down week by week and never take more than a quarter at a time. ON YOUR PHONE, NOT OURS No account. No sign-in. Your log never leaves the device. Apple Health sync works in both directions. Widgets on the Home and Lock Screen, a reminder 20 minutes before your cutoff, and one-tap logging from Siri and Shortcuts. — Sundown Pro Try everything free for 3 days. After that Pro continues as a monthly or yearly subscription, or a one-time lifetime purchase — your choice, shown in your own currency before you buy. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends. Manage or cancel in Settings on your Apple Account. Deleting the app does not cancel a subscription.
