Tell the app a little about yourself. It uses this to estimate how fast caffeine leaves your body and how much per day is sensible.
Caffeine follows a standard one-compartment model (about 45 min to peak). Blood alcohol uses the Widmark formula with body water from height and weight, gradual absorption and steady elimination. Both are guides, not medical advice, and never a test of whether you can drive.
