About
ClearCaff is a caffeine tracking and sleep-readiness app for Android. It helps users log coffee, tea, energy drinks, pre-workout and other caffeinated beverages, then estimates how much caffeine may remain active over time. Using a caffeine half-life model, ClearCaff displays a visual decay curve and estimates when caffeine may fall below the user’s sleep-ready threshold. Core calculations work offline, drink records are stored locally, and no account is required.
