About the product

Caffeine Half-Life Tracker is a multilingual browser app for recording drinks and viewing a combined timeline of estimated remaining caffeine. Adjust half-life assumptions to compare scenarios. Guest records stay in the browser; signed-in records can sync to the cloud. Results are model estimates, not measured blood concentrations, medical diagnoses or guaranteed sleep predictions. The guest calculator requires no account.
