Gratis · Diseñada para iPad
HalfCup helps you understand your caffeine consumption and sleep better. Know exactly when you'll be sleep-ready based on real caffeine science.
TIRED OF BEDTIME ANXIETY?
Stop guessing when you can have your last coffee. HalfCup uses proven half-life decay modeling to show you exactly when caffeine will clear your system. You'll see your "sleep-ready by" time after every drink.
TRACK EVERYTHING WITH CAFFEINE

LOG IN SECONDS
Quick-add your favorite drinks with one tap. No tedious searching every time. Support for partial servings (half a can, 2.5oz espresso) and decimal precision.
PERSONALIZED TO YOUR METABOLISM
Everyone processes caffeine differently. Adjust your half-life (2-10 hours) to match your sensitivity. The app uses a 30-minute absorption window for accurate modeling.
VISUAL DECAY CURVE
See your caffeine level drop in real-time. Scrub through the timeline to check your levels at any future time. Know if that 3pm coffee will ruin tonight's sleep.
