Development, in plain language
Organ by organ, sense by sense, with size comparisons that aren’t only fruit. Illustrated, and quiet about the rare things until they matter.
Stage one · in the womb
Watch them grow, one week at a time
A week is a long time in there. Each one gets its own short read: what is forming, what you might feel, and what is worth asking at your next appointment. Weeks 4 through 42 are covered, and every week you pass stays readable.
Nutrients that move with you
Iron steps up in the second trimester, so the targets do too. Log a meal, see the gap, get food ideas — iron, folate, DHA, calcium and vitamin D, without a shop full of supplements.
Your next appointment, in context
Keep the next one beside the week it belongs to, with the provider, the place and what to bring. A reminder if you want one, so it sits inside the pregnancy rather than in a separate calendar.
A note for whoever is with you
Part of each week is written for the person alongside you rather than the person pregnant: here’s what’s happening, here’s one thing that helps.

How the stage moves
The app opens here as soon as you give it a due date, and moves itself on to the birth stage from week 36 — earlier or later if you move it yourself.
The other two stages
Stage two · getting ready, and goingA birth class you can open at 3amNine short birth-class lessons, guided breathing, a contraction timer and checklists that split between you — all of it working offline.Stage three · the first yearThe first year, made legibleOne-tap logging for feeds, naps and nappies, sleep read back to you across the week, milestones as ranges and a written care library.
babybub gives general information and a place to keep your own records. It is not a medical device and it does not diagnose anything. Always ring your midwife, child health nurse or GP if something worries you.
