A baby tracker for both parents: what actually differs

Pixy is ours, and this page names competitors, so read it knowing both. What it reports is what each publisher states on its own page, read on 8 September 2026 and linked at the foot.

Sharing is not the differentiator any more

A few years ago, syncing a second phone was the thing you paid for. Now it is table stakes, and the marketing has not caught up.

Four apps, four free answers. If a comparison tells you that shared logging is what makes one of these special, it is selling you something that all of them do.

What still differs underneath

• How the second person joins. An invite code is the common pattern, and it matters more than it sounds: the person joining at 2am with one hand free should not need to create an account, find a settings screen and confirm an email.
• Whether it works with no signal. Pixy logs offline and syncs on reconnect, and Sofi states the same. A nursery in a basement, a car park, a plane — this is where a tracker either keeps the record or loses it.
• How many people can join. Two carers is the case every app handles. Grandparents plus a nanny plus two parents is where free tiers sometimes stop, and it is worth checking before you rely on it.
• Whether the app is still there in year three. The one that is genuinely different, and the next section.

The 3am test

There is one way to compare these that beats any table. Install two, and have both of you log a single real day — including the feed at four in the morning, one-handed, in the dark, without waking the other person to ask what time the last one was.

By breakfast you will know which app the two of you actually reached for, and whether the other person’s entry was there when you looked. That answers the question this page is about better than any feature list, because the failure mode of shared logging is not a missing feature — it is one parent quietly giving up on it in week two.

The question nobody asks until year two

Two parents coordinating on a newborn is a problem that lasts months. Two parents coordinating on a four-year-old — who picks up from nursery, whose turn is the bath, did anyone do the reading — is a problem that lasts years, and almost no tracker is built for it.

Of the apps here, Pixy is the one that covers it: it runs 0 to 12 and changes what it shows by stage, from feeds and nappies to potty and routines to homework and chores. Huckleberry describes itself as newborn to five. Sofi and Pippy are built around babies. Whether that matters depends entirely on whether you will still want to log anything by then, and most families stop before three — which is a perfectly good outcome and not a failure.

How to set it up on day one

• Whoever installs first creates the child profile — not both of you, or you get two.
• Send the invite before you need it, not at 3am when one of you is holding a baby.
• Agree what you will log and what you will not. Two people logging everything is worse than two people logging feeds and sleep, because the entries nobody trusts are the ones that get abandoned first.
• Give it a week before deciding. The first two days of any tracker feel like homework in every app there is.

If you are still narrowing the field, the alternatives page covers what each app charges for, and the full comparison goes through tiers and age ranges in detail.
