Support
How can we help?
Answers to common questions about setup, reminders, devices and billing. If you need more, email DuttLabs directly.
Getting started
How do I set my hydration goal?
Open Settings and use the goal calculator or enter a custom daily target. The Coach tab can recommend a target using body mass, activity, climate, weather, workout, and caffeine context, and lists each factor.
Can I undo a mistaken entry?
Use the undo banner immediately after logging, or remove the record from History. Entries linked to caffeine estimates are cleaned up with the hydration entry.
Can I change units and quick-add amounts?
Yes. Open Settings to choose millilitres, ounces, cups, or litres, then adjust the quick-add presets to match your bottles or cups.
Reminders and notifications
Why am I not receiving reminders?
Check notification permission in iOS Settings, confirm reminders are enabled inside Hydrate, review the reminder time window, and check whether a Focus mode is blocking alerts.
How do smart reminders work?
Smart reminders consider your progress, recent logging patterns, quiet hours, Focus state, snooze, and skipped reminders. They are designed to reduce unnecessary alerts when you are already on track.
Apple Watch, widgets and Health
How do I use the Apple Watch app?
Install Hydrate on Apple Watch from the Watch app on iPhone. Entries you log on the watch sync with your paired iPhone.
How do I connect Apple Health?
Enable Apple Health from Settings inside Hydrate, then grant the requested iOS permissions. You can change access later in iOS Settings under Health and Data Access.
How do widgets and shortcuts work?
Hydrate offers Home Screen, Lock Screen and StandBy widgets, a Live Activity, a Control Center button on iOS 18, and Siri and Shortcuts actions for faster logging and status checks.
Subscription and billing
What access options are available?
Hydrate offers monthly, yearly, and lifetime access. Monthly and yearly plans include a 7-day free trial when eligible. Lifetime is a one-time purchase with no trial.
How do I cancel a subscription?
Subscriptions are managed by Apple. Open iOS Settings, tap your name, choose Subscriptions, select Hydrate, and cancel before the renewal date shown by Apple.
How do I restore a purchase?
Open Hydrate and choose Restore Purchases on the plans screen or in Settings. This restores active subscriptions and lifetime access associated with the same Apple ID.
Data and export
Where is my data stored?
Hydration data is stored locally on your device. Optional Apple Health records are managed by Apple Health. Export tools can produce CSV, JSON, or PDF files when you need a personal copy.
How do I delete data?
Use Delete All Data in Hydrate’s Settings, or delete the app to remove local app data. Apple Health data can be reviewed and deleted from the Health app.
