HalfLife: Caffeine Peak, Detox
Caffeine tracker & detox timer
Free · Designed for iPad. Not verified for macOS.
Master your caffeine habit. Predict your energy peaks, protect your deep sleep, and reset your tolerance with the ultimate personalized metabolic timer.
Stop guessing. Start biohacking your energy.
HalfLife is the first smart metabolic tracker that predicts exactly when your coffee kicks in, when it wears off, and when your body is 100% clear.
Most caffeine trackers just count cups. HalfLife uses real pharmacokinetics to calculate your unique caffeine curve based on your personal biology. Whether you want to maximize your focus, cure insomnia, or quit caffeine entirely, HalfLife gives you back control over your nervous system.
CORE FEATURES:
PREDICT YOUR PEAK
Know exactly when your espresso or matcha will reach maximum concentration in your blood. Plan your deep work and workouts around your actual energy spikes.
PROTECT YOUR DEEP SLEEP
Caffeine half-life can ruin your night. HalfLife shows you the exact time your system will drop to 0 mg, so you know exactly when your daily cutoff time should be to fall asleep effortlessly.
TRACK YOUR CAFFEINE DETOX
Want to lower your tolerance or quit coffee? When your system clears, the Detox Timer automatically starts. Track your "clean streaks" in hours and days to reset your adenosine receptors.
100% PERSONALIZED BIO-MATH
Caffeine affects everyone differently. Our algorithm builds a custom elimination curve based on your unique biometric data:
• Body Weight (calculates impact intensity)
• Age & Natural Metabolism Speed
• Nicotine intake (speeds up caffeine clearance)
• Oral Contraceptives (slows down caffeine clearance)
ONE-TAP LOGGING
A beautifully dark, sci-fi-inspired interface lets you log Espresso, Filter Coffee, Energy Drinks, or Tea in one tap. See your active load vs. daily total instantly.
Take back control of your energy, crush your coffee addiction, and sleep like a baby.
