What’s in a Baby Tracker export?

Baby Tracker - Newborn Log, the app from Nighp, exports through Settings → Export Data to CSV. What you get is a zip with a separate CSV for each kind of record, named after your baby, like Alex_diaper.csv and Alex_sleep.csv. You can pick the zip here as it is, with no unzipping.

Feeds are split across three files: nursing, formula and expressed milk. Sleep, diapers, growth, milestones, medication, temperature, vaccines and other activities each get their own. Pumping is one file, pump.csv, which doesn’t name a baby.

Each row is one record. Units sit in the column names, like Amount (ml) and Duration(minutes). Times look like 2026/10/17, 11:30, and the order of the date follows your phone’s region.

Questions about Baby Tracker exports

Is my Baby Tracker file uploaded anywhere?

No. This page reads the zip inside your browser, and nothing is sent to Coo or anyone else. Close the tab and it’s gone.

How do I export my data from Baby Tracker?

In Baby Tracker - Newborn Log, go to Settings → Export Data to CSV and save the zip to Files. Pick the zip as it is, with no need to unzip it. Nighp’s older FAQ lists CSV export under its full-version purchase, and we couldn’t find a current statement.

Can I import my Baby Tracker data into Coo?

Yes. In Coo, go to Profile → Import Events → Baby Tracker, tap Choose File and pick the zip as it is. If the file has more than one baby, you pick whose history to bring in, because a Coo log is one baby’s. Coo shows a preview before anything is added and skips events already in your log.

What comes across from Baby Tracker to Coo?

Nursing, bottles, sleep, diapers, pumping, medicine, temperature, growth, vaccines, tummy time, milestones and other activities. Anything Coo has no event type for becomes a custom event named after it, with the details in its note.

Can I open a Baby Tracker export in Excel?

Yes, but one file at a time: the zip holds a separate CSV for each kind of record, so you’d have to unzip it and open them one by one. After you open your zip here, Download spreadsheet gives you one file with one tab per kind of record for Excel, Numbers or Google Sheets.

Is Coo free?

Yes. Coo is free on iPhone and Apple Watch, with every feature included. There are no in-app purchases, no ads and no account to create.

What your log moves into

One tap, then put the phone down

Every log is a moment, so there’s no timer to start, stop or forget. Tap “Feeding started”, then “Feeding ended” later, and Coo works out how long it lasted.

Tapped the wrong thing? Undo.

Every log, edit and delete shows an Undo button, going back up to 10 changes. Off by a few minutes? Hold the event and drag it to the right time.

Your partner, on their own phone

Invite a partner, grandparent or nanny through iCloud. Each of them logs from their own Apple ID, with no account to create and no password to pass around.

A shared log in Coo with the whole family

Your Baby Tracker history keeps working

Imported days sit beside new ones in the Week and Month views, so the patterns are there from day one. Hold anywhere to read them: “Asleep at this time on 6 of 7 days.”
