Waterd vs Hydrium

The hydration tracker you never open. Waterd uses Apple Intelligence on supported devices to set your daily water goal based on your activity, the weather, and how you've been hydrating this week — automatically, on-device, no cloud. On devices without Apple Intelligence, Waterd uses a built-in formula based on your weight, activity, and weather forecast. Then it gets out of your way. Tap your bottle from the Home Screen widget, the Lock Screen, the Dynamic Island, your Apple Watch, or a notification action. Each tap is one drink, logged in under five seconds. The app exists for weekly reflection, not daily logging.

Full sources and citations are inside the app under Settings → How goals are calculated, and from every screen where the goal is shown. Waterd is a general wellness app and is not a medical device.
