CaffCutoff vs Caffeine Tracker & Sleep Clock

CaffCutoff turns every coffee, tea, and cola into one number: how much caffeine is still in your body right now, and the latest time for your next cup that still lets you sleep. Log a drink in seconds from a built-in database of real caffeine amounts, then watch it fade. CaffCutoff applies the same first-order decay your body uses, across every drink you have had, so the number on your home screen is always current. WHAT YOU GET - Caffeine on board: a live total of the caffeine still in your system, updated minute by minute - Decay curve: see the rest of your day, hour by hour, as the caffeine clears - Daily total: your intake against a general safe-limit reference, with a clear under, close, or over reading - Drinks database: coffee, espresso, tea, energy drinks, soda, and more, with honest milligram amounts - Your bedtime cutoff (Pro): set your bedtime and how sensitive your sleep is, and CaffCutoff solves for the latest time to have your next drink and still be under your threshold at lights out - Projected at bedtime (Pro): how much caffeine you will still have on board when you turn in - Cutoff reminder (Pro): an optional local alert at your cutoff time, so you never miss last call - Custom drinks (Pro): save the drinks you actually order to your own library - Caffeine report (Pro): a clean PDF plus a CSV of your recent days, daily totals, peak levels, and every logged drink, to keep or share TUNE IT TO YOU Set your own daily limit, your bedtime, your sleep sensitivity, and the caffeine half-life the math uses. The numbers follow your body, not a generic average. FREE AND LIFETIME Free covers the whole tracker: logging, the live amount on board, the decay curve, your daily total, and your full history. One lifetime purchase unlocks your bedtime cutoff time, the cutoff reminder, custom drinks, and the PDF and CSV report. Pay once, keep it forever. No subscription. INFORMATIONAL, NOT MEDICAL CaffCutoff is a caffeine tracker, not a medical device. The safe limit and half-life are general references for healthy adults; the right amount for you can be lower. It estimates, never diagnoses. Talk to a professional about your own caffeine and sleep. PRIVATE BY DESIGN Everything you log stays on your device. No account, no cloud, no tracking.
