CutCaff

Stop the caffeine crash. Keep the energy. CutCaff is the only app built around how caffeine actually works in your body — using your real half-life to show you exactly when caffeine leaves your system, and building a personalised taper plan so you never have to suffer through cold-turkey withdrawal again. Whether you're tired of 3am wide-awake nights, afternoon headaches, or being chained to your coffee habit — CutCaff gets you out, gradually, without the pain. THE BODY TANK Watch a real-time display of how much caffeine is still active in your body right now. As the day goes on, the tank drains. When it's clear, you sleep. It sounds simple — but it's the first time most people really understand why their sleep is broken. YOUR PERSONALISED TAPER PLAN Cold turkey causes headaches. CutCaff reduces your intake by ~10% every few days — the science-backed pace your body barely notices. Tell us where you are. We'll show you the way out. THE HALF-LIFE CLOCK Caffeine has a half-life of 5–6 hours. That espresso at 4pm? Still 50% active at 9pm. The clock shows you exactly when it's safe to sleep — and builds the case for your own cutoff time, using your numbers. CRAVING TOOLKIT When the urge hits, CutCaff gives you four tools: breathe through it, swap for something else, log what triggered it, or start a 20-minute delay timer. Most cravings pass in under 20 minutes. We help you wait them out. THE DETOX ENGINE (GAMIFICATION) Your progress is tracked as a Dependency Score — a number that drops as you taper. Watch it fall week over week. Earn Detox Points for every drink logged, every craving resisted, every day on plan. Protect your streak with Streak Shields. Unlock titles as you go: from Caffeine Addict to Detoxed. SLEEP. SYMPTOMS. CORRELATION. Rate your sleep every morning in 5 seconds. Log any withdrawal symptoms. After two weeks, the charts make the argument for you: less caffeine, better sleep. No guesswork. Just your own data. SMART NOTIFICATIONS (LOCAL ONLY) CutCaff never tracks your location. All reminders use your phone's local time — a cutoff warning before your last drink, an evening log reminder, a morning sleep rating, and a streak alert if you're about to lose your run. Every notification type is customisable. CUTCAFF PRO Unlock everything with CutCaff Pro.
