## Description

**Willo** is a baby tracker and parenting companion for newborns through age 6. Track naps, wake windows, bedtime routines, moods, milestones, and developmental changes from a personalized daily dashboard. Its 35 developmental phases help parents understand changes in sleep, mood, behavior, and new skills before they happen.

Willo includes an AI parenting assistant for on-demand, science-based guidance about baby sleep, feeding, milestones, emotional changes, and parent wellbeing. A built-in sleep sound library offers white noise, pink noise, womb sounds, lullabies, ocean waves, and gentle frequencies to support calmer sleep routines.

Parents can also receive bite-sized, age-matched guidance, create a mood journal, save one photo a day in a private memory book, and connect with an in-app community of caregivers. Premium features require a subscription. Willo is for informational purposes only and is not a medical device or substitute for professional medical advice.
