Thoughtful by default

A small companion, not another health dashboard.

Tap your vessel

Set the amount your glass, bottle, or tumbler adds. Ice can be included as a simple fill estimate.

See today clearly

A calm progress view shows what you logged, what remains, and your recent sips without streak pressure.

Stay on your device

No account, ad network, analytics SDK, or app-managed cloud sync. Your entries stay in Gulpie’s local app storage.

Helpful, not medical

Context over false precision.

Gulpie’s goal is an editable starting point based on population reference values for beverages. Food and other drinks also contribute water, and individual needs vary.

Gulpie does not diagnose dehydration, prescribe intake, or calculate caffeine, calories, electrolytes, or nutrition.

Reminders are local and best-effort. iOS may delay or hide them because of Focus, notification settings, summaries, or device state.
