Track your caffeine and sleep better. See exactly when today's coffee wears off. Caffeine Clock is a caffeine tracker that models absorption and half-life to estimate how much caffeine is in your system throughout the day.

Caffeine Clock models how quickly you absorb caffeine and how it declines (half-life), then estimates your level now and later.
