Overview
ClearHalf turns caffeine and alcohol from a guessing game into a clear forecast.
Log a coffee, tea, energy drink, or a glass of wine, and ClearHalf shows your Body Clock, an hour-by-hour curve of how much is still in your system and the exact time you'll run clear. Set your bedtime and it warns you when a late cup will still be working at lights-out.
