AI hydration on autopilot

Features & Capabilities

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.

PREMIUM — three ways to unlock • Monthly — $1.99/month with a 7-day free trial • Yearly — $4.99/year • Lifetime — $7.99 one-time purchase

All three unlock the same premium features: • Personalized daily hydration goals that account for your activity and the weather • Weekly insights that explain your hydration patterns in plain English • Runs entirely on-device where Apple Intelligence is available

ZERO FRICTION • Home Screen interactive widgets • Lock Screen widgets and StandBy support • Apple Watch complications and Smart Stack widget • Live Activity in the Dynamic Island • Notification action buttons that log without opening the app

PRIVATE BY DESIGN • All data stays on your device. No accounts, no email collection. • Apple Intelligence runs entirely on-device where available. • HealthKit-compatible. Your water intake syncs with Apple Health. • No tracking. No ads. No social feeds.

HOW GOALS ARE CALCULATED Waterd suggests goals based on widely-cited references (National Academies of Sciences, Mayo Clinic, ACSM, CDC). 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.

SUBSCRIPTION TERMS Monthly and Yearly are auto-renewable subscriptions charged to your Apple ID. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Free trial converts to a paid subscription at the end of the trial. Manage or cancel in Settings → Apple ID → Subscriptions.
