        <h3>Health Calculator FAQ</h3>
        <p><strong>Are these calculators free?</strong><br>Yes, all HealthKit calculators are free and available without signup.</p>
        <p><strong>Which calculator should I start with?</strong><br>Most users start with calories (TDEE), then protein and macros for intake targets, and BMI as a quick screening metric.</p>
        <p><strong>How does the hydration tool estimate water intake?</strong><br>It uses a bodyweight baseline and adjusts for activity and hotter climates to generate a practical daily hydration target.</p>
        <p><strong>Can calculator results replace medical guidance?</strong><br>No. These tools provide estimates and should be combined with advice from a licensed clinician when needed.</p>
