Your baby's diary, one step ahead
Stay a step ahead of your baby's rhythms.
Xiaobaby learns when he eats and when he sleeps, and tells you when he is likely to ask again or wake up. And you log it by voice, without putting him down: “Hey Siri, Xiaobaby: ninety millilitre bottle.” Free for the first 7 days.

By voice
You can't type with a baby in your arms.
So whatever isn't logged right away gets forgotten. Say “90 ml bottle”, “fell asleep” or “dirty nappy ten minutes ago” and it's logged at the right time. Xiaobaby answers with the day's total, so you can hear it got it right.
With Siri on the iPhone, or with the app's own microphone on any phone. And if it gets one wrong: “delete the last one”.
With Siri, without opening the app
Hey Siri, Xiaobaby
What should I log?
Ninety millilitre bottle
Logged: a 90 ml bottle of formula at 15:42. 410 ml so far today.
Sleep
Roughly when he will wake up.
Every nap teaches something. After a few days of logging, Xiaobaby knows how long your baby usually sleeps and tells you when he is likely to wake. So you know whether there is time for a shower.
And when he's awake, when he usually drops off again.

Peace of mind
It tells you when something is out of the ordinary.
Nappies, weight, feeds: Xiaobaby compares what you log with what paediatricians expect at his age, and tells you when it's worth a call.
Every notice says where it comes from, without crying wolf. It does not replace your paediatrician.

Feeds
How much he has eaten, and whether it's enough.
Breast, bottle or both. You see what he has had today against what a baby of his weight needs, and when he usually gets hungry again.
No calculator at four in the morning.

The day
Everything that happened, in one list.
One tap to start the feed or the nap, another to end it. If you missed something, add it at the right time. And whoever looks after the baby with you sees it on their phone straight away.
Every entry carries the name of whoever made it.

One tap at 4 am
The big buttons are on the first screen. No typing, no searching.
Any way of feeding
Breast, a bottle of expressed milk, formula, or a mix.
As many babies as you like
Twins, siblings, or the baby you look after. Switch from the top.
Built for the dark
Dark mode and big numbers, readable with one hand and half an eye.
With your AI
Ask your AI about your baby.
Connect Claude, ChatGPT or whichever AI you use, and it will have the diary in front of it: ask how he slept this week, when he last ate, or whether his weight is on track. And if you like, let it log for you.
Connect it from the app in a minute, and you decide whether it only reads or also logs.
Your AI, with the diary in front of it
How has Pablo slept this week?
Between 14 and 16 hours a day, a little more than last week. Last night the longest stretch was 4 h 10, from 23:50 to 04:00.
And when did he last eat?
At 14:20, a 90 ml bottle. He usually asks again around 17:10.
Three steps and you're running.
Add your baby
His name and when he was born. That's enough to start.
Log it as it happens
By voice, or with one tap when the feed or nap starts and another when it ends.
Read the day
How much he ate, how much he slept, and what comes next.
Free for a week. Then 15 €, once.

Questions parents ask.
What happens when the week is over?
Nothing is deleted: everything you logged stays visible. What stops is logging new things, until you pay the 15 €.
How does the voice part work?
On the iPhone, with a Siri shortcut you set up in a minute from the app: you say “Hey Siri, Xiaobaby” and then what to log. On any phone, with the microphone built into the app.
Does it work if I breastfeed?
Yes. You log when each feed starts and ends, and the side. If you also bottle-feed, it all adds up together.
Can my partner or a grandparent use it too?
Yes. You send them a link and they see it on their own phone, with their own account. You decide whether they can log or only look.
Can I ask Claude or ChatGPT about my baby?
Yes. From the app you connect whichever AI you use, and it can read the diary, and log if you allow it.
Do I need to install anything?
No. It opens in the browser and, if you like, goes on your home screen like any other app.
Is it a medical device?
No. The notices draw on public paediatric guidance so you know when to ask. The answer comes from your paediatrician.
Fewer doubts at four in the morning.
Free for 7 days. No card, nothing to install.
