The Calclytix Water Intake Calculator is an advanced hydration tool designed to calculate your optimal daily water requirement based on weight, age, gender, activity level, climate, sweat rate, and pregnancy or breastfeeding status. This calculator goes far beyond the outdated “8 glasses per day” rule by offering a science-based hydration recommendation tailored to each individual.
The tool uses multiple evidence-based formulas, including weight-based hydration guidelines, activity-level hydration correction, climate adjustment, and an optional body surface area (BSA) method for more precise hydration calculation. Users also receive a complete hydration schedule, bottle/cup breakdown, hydration score, personalized reminders, and a clean progress visualization chart.
Designed for everyday users, fitness lovers, athletes, office workers, and pregnant or breastfeeding women, the Calclytix Water Intake Calculator offers advanced hydration insights such as sweat-loss estimation, dehydration risk alerts, sports hydration mode, and electrolyte suggestions for long workouts. The built-in daily tracker allows users to log water intake, view streaks, export reports, and track weekly progress.
Whether you want to improve your health, boost your workouts, combat dehydration, or build hydration habits, the Calclytix Water Intake Calculator provides an accurate, personalized, and user-friendly approach to daily hydration.
