About
Quit Caffeine shows what coffee is actually doing to you — right now. ■ Your body's caffeine curve Log a drink with one tap and watch your body's caffeine level decay in real time on a live half-life chart. See exactly how much is still in your system at bedtime. ■ Sleep guard Set your bedtime and a sleep threshold. The app tells you the latest time for your last coffee — and warns you when one more cup would wreck tonight's sleep. ■ Taper or quit — your choice Reduce week by week with a gentle taper plan, or go caffeine-zero and count your streak. Both modes track your progress. ■ Caffeine withdrawal timeline Know what commonly happens after cutting back — headache peak around days 1–2, energy dips, then steadier sleep and focus within weeks. General, science-informed info with milestone reminders. (Not medical advice.) ■ Built-in drink database Espresso, drip, cold brew, teas, energy drinks, cola — realistic caffeine amounts per size, plus custom entries. ■ Private by design No account. No cloud. Everything stays on your device. One-time purchase removes all ads permanently.
