Kids & Growth

Everything true about
one small person

The Kids tab is your child's own record: how they're growing, the firsts they've reached, their timelapse rituals and their jar of sayings. All of it gathers from every chapter of your family's life, so a first the daycare worker wrote down counts exactly as much as one you saw yourself.

Growth

The one thing you can’t see happening

Write down how tall they are, what they weigh and how big their head is — on the day of the check-up, or the evening you finally got them to stand still against the door frame — and watch those numbers turn into a line that climbs. Growth is the one thing you cannot see while you live it. This is where it becomes visible.

Behind your child's sage line sit the WHO growth standards: the soft bands showing where most children of that age and sex fall. Your line is the story; the bands are just the room it's walking through. Tap a dot and it tells you the measurement, the date, their age that day and the percentile — plainly, with no alarm colour anywhere on the screen, because a number about a child is never an alert.

Logging takes one sheet: the date, then any of the three fields. Fill in one, or two, or all three — a measurement with no measurements isn't one, so Save waits for at least a number. Log again on a day you already have and it doesn't duplicate: it fills in what's missing and updates what you changed. Weighing at home in the morning and being measured at the doctor in the afternoon quietly become one day's record.

  • Height, weight and head circumference — a segmented switch picks which one the chart shows
  • The WHO 3rd, 15th, 50th, 85th and 97th percentiles, drawn quietly behind your own line
  • One entry per day, merged rather than duplicated when you come back to it
  • Empty one field and just that measure clears — a wrong height doesn’t take the right weight with it
  • Everyone in the family reads the same growth record; the grown-ups who run the family add to it

Their firsts

A shelf of what they’ve already done

Every first this child has reached sits in a rail you can swipe through, each with the photo of the day it happened and how old they were. It's the answer to “when did she first walk” — one tap away, and the same answer for everyone in the family.

Above it, the tab opens with the next first worth watching for and roughly when it usually happens — “Often around 7 months”. It's a hint, never a deadline. And if you haven't saved a birthday yet it asks for that first, because nothing can be suggested without one.

  • The reached firsts as a swipeable rail, with “See all” into the full catalog
  • The hero names whichever first sits closest to this child’s own age
  • No birthday on file? It asks for that instead of showing an empty card
  • A photo of three children can record one child’s first and nothing for the other two
  • Firsts gather from every chapter — the daycare’s and yours read the same

The Jar

The things they said, kept like photographs

Somewhere around two, they start saying things you promise yourself you'll never forget — and then you do. The Jar is where those go: “Every funny, tender thing they've said.” Each one gets a big card of its own with no picture on it, a small gold quote mark, and the words in warm italics with room to breathe. They're deliberately bigger and quieter than photo cards, because here the words are the whole point.

The most recent one sits in full on the Kids tab, so the last funny thing they said greets you when you open it. If the jar is still empty, the prompt takes you straight to the composer with the caption already relabelled “Their exact words” and asking “What did they just say?”

  • Sayings are grouped under the day they were said, with more loading as you scroll
  • Each quote is signed with their face, their name and the day
  • The jar belongs to one child, because a merged jar isn’t a thing anyone reads
  • They still live in your timeline too — the Jar is just where they aren’t buried between pictures
  • A saying goes to the whole family automatically, the same way a first does

One at a time

One child, and the whole family’s record of them

The name at the top of the Kids tab is the app's only switcher. Tap it and growth, milestones, timelapses and the jar all re-scope to whoever you picked. There is deliberately no “all children” view: a merged growth chart or a merged jar isn't something anyone reads, unlike the timeline, which is family-wide precisely because a merged feed is meaningful.

What the tab shows, though, is everyone's work. These are facts about the child rather than posts, so they gather across every chapter and read the same for the whole family — nobody's copy of when she first walked is different from anybody else's. The choice of child is remembered on your device, so the tab reopens on whoever you last had open.

The small things

Calm about a child, not clinical

The details that keep a child's own record feeling like a keepsake page rather than a chart at a check-up.

Empty is an invitation

Every section renders even with nothing in it. The child who has never been measured is exactly the one the growth card has to reach, so it says “Nothing measured yet” and opens the same screen. Whoever may act on it gets a soft dashed invitation; whoever may not gets a quiet note instead of a bare heading.

No alarm colours, ever

A measurement outside the usual bands is shown in muted text with a plain explanatory note — never red, never a warning triangle. Growth data here is treated calmly and factually, because you are a parent looking at your child, not a clinician reading a chart.

It’s called by their name

With one child there's nothing to switch between, so the tab drops the word “Kids” and simply says “Mia”. The switcher appears the day a sibling does.

It opens where you left it

Which child you were reading is saved on the device, so the tab reopens on them. If that child is removed on another phone, it quietly falls back to the first one left rather than showing you an error.

74,5 in German

Type a comma where your language uses a comma, and that's how it reads back. Ages are written out the way you'd say them — “11 months”, “1 year, 2 months” — never as a decimal number of years.

A second way in

Growth also has a row on the child's own edit screen, under their name and birthday, for when you're already there. Birthday and sex are both optional — the birthday unlocks the gentle first-suggestions, the sex only picks which WHO curves the chart compares against.
