Log water without opening the app.
We built a widget that lives on your home screen. Two quick add buttons (200ml and 330ml) mean you can track your hydration with a single tap. No app launching, no waiting, no friction.
MULTI DAY INTELLIGENCE
The widget adapts based on your habits. Active today? See your progress with quick add buttons. Yesterday's achievement? We celebrate it and prompt you to sync. Been away for a while? Smart detection knows when to show sync reminders versus fresh start buttons.
