About Caffeine Half-Life Tracker
Caffeine Half-Life Tracker is a browser-based calculator for recording drinks and exploring how estimated caffeine amounts change over time. Each recorded drink has its own intake time, and the tool combines the estimates in one curve. Visitors can compare different half-life assumptions and use a beverage library to add entries. Guest records stay in the current browser; signed-in intake logs can sync to an account. Results are educational estimates, not blood concentrations or a prediction of when someone can sleep.
