Getting started

1. Complete setup

Review the introductory information, choose the profile options you want to share with the app, and acknowledge the hydration-support disclaimer. Hydrion can still use a manual goal when optional profile or weather inputs are unavailable.

2. Choose units

Select millilitres or fluid ounces. Hydrion stores canonical measured volumes and displays amounts in your selected unit.

3. Set or accept a goal

Choose a manual target or enable weather-informed assistance. A weather suggestion is shown for review; it does not silently replace your goal.

4. Log your first drink

On Home, choose a quick amount, saved container, or custom amount. Enter what you actually drank, then confirm. The same hydration record updates the dashboard and every eligible active challenge without duplicating the daily total.

Themes

Hydrion supports Day, Night, System, and Dynamic appearance choices. System follows the device theme; Dynamic can adjust according to time of day.

Optional wake and sleep schedule

Add a schedule in Body Metrics when you want waking-hour pacing. Overnight and shift-work schedules are supported. The schedule affects pacing only and never changes the daily goal automatically.

Choose permissions in context

Enable notifications when creating reminders and location when requesting weather assistance. Choosing Not now keeps Hydrion usable; these permissions remain independent.
