About this app

Track their words, watch their world.
Hatsu-go is an app that helps you record your child’s growing vocabulary and how much they understand. It lets you keep track of how your child’s understanding grows and how the way they see the world changes.
The joy and surprise of your baby’s first words. New words that keep growing. Funny little mistakes you can only hear right now. And a clear “Mama” or “Dada.”
With Hatsu-go, you can record each word with video along a timeline. As your child’s words grow, you can also look back on the moment, the situation, and how it felt.

A Speech and Growth Log Made by a Parent
The developer is also a parent of a daughter with developmental needs.
Because of this, the app lets you record each word in detail, including whether it was spoken on their own, imitated, or understood, along with the situation in which it was spoken.
The monthly summary and chart features let you see at a glance when a word was first used, in what situations, and how it grew over time.
Of course, it is also useful for families of neurotypical children. It is designed to help parents explain their child’s progress more easily and clearly during well-child visits or developmental evaluations.
The core features that support your parenting, like logging and charts, are completely free and unlimited to use.
