THE METHOD
HALFLIFE calculates your real caffeine intake, builds a week-by-week taper, and tells you exactly when withdrawal peaks and passes. Cold turkey fails 80% of the time. This doesn't.
Log your first drink. See your real daily intake — most people guess 40–60% low.
Peak withdrawal. The app tells you when symptoms hit and when they end.
Sleep restores. Natural energy returns. Your body is recalibrating.
Caffeine-free. Without the horror story.
Clinical grade. Calibrated. Calm.
Based on DSM-5 criteria and clinical taper protocols.
