Less guessing, more cuddles.

How did Mia sleep this week?
Better than last week — 14 h 20 m a day on average, up 35 minutes. She woke twice most nights instead of three times.
When is the next nap likely?
Around 13:40, in about 40 minutes. She's been awake 2 h 13 m.
Ask anything, or just talk…

Log it in seconds

The whole day,
in a few taps.

One tap starts a timer. Two taps save a feed. The cards you actually use sit on the home screen, in the order you put them — and each one remembers when it last happened.

Feeding, however you feed

Breastfeeding with a live timer and sides, bottles in ml or oz, solids with the food, and pumping. The timer survives an app restart — and keeps running on your lock screen.

Sleep, without the maths

Start it when she goes down, stop it when she's up. Esti splits day and night for you and adds it up — so "how much did she actually sleep?" stops being a calculation at 2 a.m.

Night · 10 h 05 m Naps · 4 h 15 m

Diapers, walks, baths

The ordinary rhythm of a day — logged in one tap, counted for you.

Health, kept in one place

Temperature, medicine, illness, vaccinations and doctor visits — each with its own form and its own reminder.

Moments worth keeping

Moods, milestones and photos — the diary half of a tracker, not an afterthought.

New · Solids

From the first spoon
to the family table.

A library of 172 foods. Each one shows the age it can be given from. You can see at a glance whether it is an allergen and how much of a choking risk it carries. Open one to see how to serve it at 6, 9 and 12 months: the form, and what to pair it with.

One entry, and the rest follows

Log a meal by what was in it. The allergens, the food groups and what to offer next are all worked out from that, and every food keeps its own history.

A reaction is its own entry

Log the food, the symptom and a photo. Until you say it is over, Esti does not suggest that food or any new allergen.

The library and logging are free. Serving by age, what to offer next, the allergens and the food groups are part of Premium.

The nine allergens, one at a time

Egg and peanut come first: they are the two with the strongest evidence for early introduction. Esti counts the tries and suggests the next allergen only once the current one is on the menu.

What to offer next, from your own diary

First, the food you started and have not finished. Then the group that is furthest behind. And when neither applies, something new. Nothing is made up: it all comes from what you logged.

See the pattern

Your baby already
has a rhythm.

Seven days, one row each, midnight to midnight. Sleep in lavender, feeds in green. Nobody has to explain what it means — you'll see the shape of your own week in about two seconds.

Settling

Eight sounds
for falling asleep.

Start one while you settle her and let it run with the screen off, for as long as it takes. The controls sit on your lock screen, so you never have to open the app in a dark room.

1

It never cuts out. When the timer runs out the sound fades away slowly, so the silence does not startle her awake.

2

Safe to leave on all night. The sound stays even, with no seam or repeat you would catch yourself listening for.

✨ Esti, your assistant

An assistant who
has read every note.

Ask her anything about your baby and she answers from your own records — not from the internet's average baby. Send a photo of a rash or a formula label. Or don't type at all: say it out loud, in any language, and she prepares the card for you to confirm.

Grounded in your data

"How did she sleep this week?" is answered with this week's actual sleep.

Log by voice

"She fed on the left for twenty minutes" — Esti fills in the card, you tap save.

Predicts the next sleep

A window, not a guess — and a heads-up when a regression begins.

Growth

Watch them grow,
worry less.

Weight, height and head circumference plotted against the WHO growth standards — the same curves your pediatrician uses. Metric or imperial, your choice; Esti stores one and shows the other.

For the appointment

A report for
your pediatrician.

Pick a period and Esti prints a PDF: growth against the WHO corridors, sleep and feeding averages with the spread behind them, medicines grouped into courses, and the health events of that period as a list. It is the visit brief you would otherwise try to remember out loud.

1

Three growth panels, not one — weight, height and head, each in its own WHO corridor, with how much it moved and how fast (+110 g · 15 g/day).

2

Every average carries its spread — "4.3 (1–9) feeds" — because an average hides the day that was a one, and that is usually the day worth talking about.

3

What is missing is named. A line lists what had nothing logged, so a doctor can tell "no nappies" from "nappies not tracked". Numbers and the WHO reference only — Esti never writes "low" or "not enough".

4

Solids, once they start. How many different foods and groups were on the table, and which were tried for the first time. Every reaction, and how long after the spoonful it showed. And where each of the nine allergens stands.
