Week by week
Each week written on its own: your baby's length and weight, what is developing, what is changing in your body, and things worth raising at your check-up.
November 2026 · iOS and Android
By your side
through pregnancy.
Wombly is a pregnancy journal. You record your measurements, read what changes each week in you and in your baby, and hand your doctor a single page when you go in for a check-up.
An AI companion in your pocket that knows your records by heart.
Ask the question that hits you at 2am; let the assistant answer from your own data.

From your baby · 21:00“Today I’m about the size of a corn cob.”
01 Principle
Wombly does not decide what a number means for you.
It shows the published range and names its source. It shows where your entry sits inside that range. Then it stops.
Your entry122
Example
100110135145
The range ACOG publishes for pregnancy. Your entry is inside this range.
No green check
No red alert
No adjectives
Shows the range
Enter your weight, blood pressure or blood sugar, and the published range for that measurement appears right beside your number.
Names the source
Underneath the range you will find who published it. You never see a number without knowing where it came from.
Leaves the rest to you
You see where your entry sits in the range. That is where Wombly stops. The rest is a conversation for your next appointment.
02 What's inside
Everything you record, in one place.
A few short sessions a day, usually one-handed. Every screen was built for that.
Measurement log
Weight, blood pressure, blood sugar, belly circumference, sleep, mood. Every entry dated, with the gestational week beside it.
Kicks and contractions
Kick counter and contraction timer. On the sofa, one-handed, one tap.
Getting ready
Hospital bag, birth plan, baby room. They arrive filled in; you remove, add and make them yours.
Baby
Name suggestions, a zodiac card, and each week a comparison of your baby's length to something you already know.
Assistant
Reads your own records and answers your questions. Where it cannot answer, it says plainly: “I can't tell you that.”
03 One page for your doctor Premium
One page at your appointment.
Pick a date range. Wombly summarizes it day by day, writes the gestational week beside every row and downloads it as a PDF. Made to be read standing up, in a few seconds.
