Know what you drank. See what remains. Cafade turns coffee, tea, soda, energy drinks, and custom entries into a calm, visual estimate of caffeine remaining throughout your day. LOG IN SECONDS Search the US catalog, repeat a recent drink, or enter a custom caffeine amount. Edit or delete an entry when plans change. SEE THE CURVE Watch each drink fade over time with a simple half-life model. Scrub through your day to understand how earlier logs can still contribute to your current estimate. PLAN YOUR LAST CUP Set a personal bedtime and see when your estimated caffeine is likely to fall below your chosen level. Use the curve as a guide for your own routine.
