The baby tracker I built for my own newborn.

Feeds, diapers, sleep and growth — in one calm app that tells you what actually matters: are they on track for their age?

37 / 100 spots claimed

Why it exists

As a new mom I was drowning in clunky tracking apps — none told me if they were actually doing okay. So I built the one I wished existed.

The screens — and why they exist

Every chart here started as a 3am question I couldn't answer.

Daily milk intake plotted hour by hour with a line for each recent day

Hour by hour, last 7 days

Is he actually drinking less, or does it just feel that way?

This one came from a real panic. Some mornings it felt like he barely fed between 9am and noon — but was that true, or just a foggy memory? So I plotted every day as its own line, hour by hour, over the last seven days. Now I can see at a glance: if this morning sits below the others, it's a real dip. If the whole week droops in that window, it's just his rhythm. One chart turned my guessing into something I could actually see.

Today at a glance

A daily target set by his weight — next to his diapers

Every app gave me the same round number for “how much a baby should eat.” But he isn't every baby. I wanted a target that moves with his weight, sitting right next to his diaper count — because together they tell me far more than either alone. If intake is low but his diapers are fine, I can breathe.

Built for one hand

Log a feed in the seconds you actually have

Every feed already had me holding a baby, a bottle, and my last shred of patience. I had no third hand for a fiddly form. So logging is a couple of taps — start, amount, done — fast enough to do mid-feed without putting anything down. The data is only honest if it's easy.

Intake trend chart against the healthy range

Days vs. the healthy range

One glance: are we inside the range or drifting out?

A single day tells you almost nothing — newborns are wonderfully erratic. What I needed was the shape of the week against the band of what's normal for his age. When the bars stay inside the range I stop second-guessing; when they start drifting, I notice early instead of at the next appointment.

On the WHO curves

Growth on the real curves, in plain language

Percentiles used to terrify me — a number with no context feels like a verdict. So I plot his weight right on the WHO curves and say it in plain words: he's following his own line steadily. Seeing the curve, not just a scary figure, is the difference between worry and reassurance.
