How the Newborn Baby Tracker works, step by step

Four moments from real use — the screen changes as you read.

Any hour of any night

One screen, when you're too tired to think.

Last feed, last sleep, what's due — the overview is built for someone running on four hours.

Across the first year

A timeline of what's coming.

Milestones, checks and appointments laid out, so the year has a shape instead of a blur.

Every feed and nap

The care log that answers 'when did she last…'

Feeds, sleep and nappies recorded in a tap, because you will be asked and you will not remember.

At the clinic

Vaccines, tracked properly.

What's had, what's due, when — the record you're asked for, in the place you'll look.

What the first year adds up to

The newborn tracker records every feed, sleep and nappy in a tap. Set the daily rate and see the year it becomes.

Feeds a day8

At 8 feeds a day that is about 2,920 in the first year.

The care log records each one in a tap, which is the only way this stays trackable.

Care — running on the sample data.

No account. No cloud. No catch.

It's one HTML file that runs in your browser. That single fact is what makes all four of these true.

That last one is the proof of the others. An app that keeps working with the internet switched off is an app that isn't sending anything anywhere.

Newborn Baby Tracker FAQ

Does the Newborn Baby Tracker need a subscription?
No. You buy the file once on Etsy and it's yours. Nothing renews and there's no account to keep.
What sections does the Newborn Baby Tracker have?
11 main sections: Dashboard, Timeline, Care, Vaccines, Appointments, Growth, Milestones, Memories, Health, Analytics, Expenses. Sample data is already in all of them when you open it, so you can see how each one works before you put your own information in.
Where is my data stored?
In your own browser, on your own device. Nothing you type is sent to us — we have no server that could receive it. That also means clearing your browser data clears the app, so keep a copy of anything you'd hate to lose.
Does it work offline?
Yes. It's a single file that opens in your browser, so once you have it you don't need to be online.
What devices does it work on?
Any device with a modern web browser — Windows, Mac, iPad, Android tablet, phone or Linux. There is nothing to install and no account to create.
Can I use it on more than one device?
Yes — the same file opens anywhere. But because nothing is stored on a server, what you type on one device stays on that device; the two copies won't sync. Most people keep it on the one they actually plan on.
How do I get the file after I buy it?
It's an instant digital download from Etsy. As soon as Etsy confirms your payment the file is in your Etsy Purchases, and you can download it again from there any time you're signed in.
What exactly do I get?
The planner file itself, a Help tab built into the app so the manual travels with it, and sample data you can load and clear in one click. Light and dark mode, and print-friendly views.

You've already used it. That was the demo.

If the app above felt right, the file you buy is exactly that — minus the sample data, plus your own real life getting calmer.
