Understand what your baby is going through now.
And what comes next. Your baby's stages, for free, each with a beginning, a middle, and an end. Lu is with you through all of them and keeps what you lived.
The stages are free. Premium comes with 1 month free.

The current stage
Right on your baby's screen, for free
Some weeks the baby cries more, only wants to be held, and sleep turns upside down.
It may be a stage. Cada Fase shows the current one and what usually comes next, always in age ranges, never as an exact date.
The nights blur together and sleep becomes a haze.
Log naps with one tap and watch the haze turn into a pattern, day after day.
The first year goes by and you fear losing the details.
Every moment, every milestone, and every photo, kept in one place. Nothing gets lost.
What stays
The truth is, no one remembers everything. And that's okay, that's what we're here for.
Hi, I'm Lu.

Your baby's stages, for free. And what you lived, kept in one place.
Your baby's stages
The current stage right on your baby's screen, and all of them in a list: what many families notice, what is happening inside, and what usually comes next. From birth to 20 months, using corrected age for preemies.
Moments and milestones
One line and, if you like, a photo. The first smile, the first steps, and everyday life, free and with no limit.
What to expect
Lu looks at your baby's stage and tells you what usually shows up now, so you can look ahead with peace of mind.
Today's portrait
Every day at 9am, Lu asks you a question about where your baby is right now, to answer with a tap. With Premium, she also tells you what she noticed in your recent logs and what usually helps at this stage, always leaving the last word to your pediatrician.
Sleep
Log sleep with a few taps. After 5 days of logging, Lu predicts the next sleep window.
Week in Review
The week flew by and you barely saw it go. Lu gathers what you logged and tells you how it went, in a one-minute read.
Sounds that soothe
White noise, rain, lullabies, and more, with a timer and on the lock screen.
Outfit of the day
The app combines the weather forecast with your baby's age and suggests the outfit of the day, also in the widget.
