Store description excerpt
See what remains. Plan what comes next. CaffTrace turns your caffeine log into a clear estimate of what may still remain over time, then helps you plan an estimated caffeine cutoff around your bedtime. LOG CAFFEINE IN SECONDS Choose a familiar drink preset or enter the caffeine amount directly in milligrams. Adjust the amount and time whenever a label differs. FOLLOW YOUR DAILY TRACE See a simple curve of your estimated remaining caffeine throughout the day, including amounts that may carry over from earlier drinks. PLAN AROUND BEDTIME Set your bedtime, preferred remaining-caffeine threshold, reference drink, and estimated half-life. CaffTrace calculates an estimated cutoff time for that reference amount. REVIEW AND CORRECT YOUR HISTORY Browse entries by date, edit a saved drink, remove an entry, or clear your caffeine history whenever you choose. ENGLISH AND KOREAN Use CaffTrace in English or switch the entire app to Korean from Settings. PRIVATE BY DEFAULT Your caffeine log and calculation settings stay on your device. No CaffTrace account or first-party tracking server is required. The free app includes Google Mobile Ads, with privacy choices and details available in the app and privacy policy. CaffTrace uses a simple exponential half-life model. Displayed values are estimates, not measurements, diagnoses, treatment advice, or medical safety limits. Caffeine metabolism varies by person, and the model does not reproduce absorption or actual blood concentration.
