Water tracking
Add water in oz or ml from Nutrition — use your bottle sizes for one-tap logging.
Water lives on the Nutrition tab, separate from meals. The goal can move with body weight and activity so a high-output day asks for more fluid.
Log water
- Open Nutrition.
- Find the water section under the macro rings.
- Tap a quick-add bottle, or enter a custom amount in oz or ml.
You can define personal bottle sizes (for example, a 24 oz bottle) so one tap matches what you actually drink.
Watch and Health
You can log water from the Apple Watch Nutrition tab. Those logs sync to iPhone. Optional HealthKit write can send water to Apple Health — see Apple Health nutrition sync.
Hydration target
The hydration target scales with body weight and active calories. It is a wellness prompt, not a medical prescription. If Adaptive Macros are on, activity adjustments can also nudge calories — water is still logged independently.
