Step 01 — About this tool
What it helps you do
The Biometric State Tracker is a smart hydration tool that helps you understand how much water your body may need each day — not based on guesswork, vibes, or that one bottle you keep refilling emotionally. This tool uses your real daily inputs, including weight, activity level, caffeine intake, alcohol consumption, temperature, humidity, sleep hours, and optional HRV data, to calculate a hydration target that reflects your body, environment, and routine.
