Not step-counter civilians SET YOUR BASELINE Your target comes from your body weight using the American College of Sports Medicine (ACSM) protocol, not a generic "8 glasses a day" number TRAINING MODE Select Easy, Moderate, or Hard and your daily goal adjusts using the Galpin equation based on body weight and workout intensity ONE-TAP LOGGING Tap the gauge to log, long-press for custom amounts, or log from your widget or lock screen without opening the app SMART REMINDERS Hourly pacing that adjusts to your progress, backs off when you're ahead, and nudges when you're behind HYDROX PRO • Apple Watch app with gauge and complications on any watch face • Log from your wrist in a single tap • Adaptive Hydration that reads workout data from HealthKit and adjusts your daily target automatically • Auto-intensity based on heart rate, so a hard session pushes your target up and a rest day keeps it at baseline THE SCIENCE Baseline from ACSM guidelines. Training intensity from the Galpin equation. Race Packs cite 16+ studies on sodium loading, HRV monitoring, and post-exercise rehydration. WHOOP research links hydration to higher HRV. And coffee counts as hydration (Killer et al 2014).
