A baby tracker you can share

Two people, one night, and a record neither of them has to be woken up and asked about. Sharing is how this app is built, not a feature bolted onto the side of it.

Invite whoever's on duty

A partner, a grandparent, a nanny, a friend doing the four o'clock shift. You send them a link from Settings. Opening it asks them to sign in first (no password to invent or remember, just a link to their own email address) and then shows them the invitation, ready to accept.

There are two kinds of invite. A caregiver logs feeds and sleeps alongside you, and every entry says who logged it. A viewer sees the whole day and changes nothing, which is the right shape for a grandparent who wants to know how the night went without being handed the controls.

Invite links last a fortnight, and the household owner can revoke one or make a new one whenever they like. Children and invites are managed by the owner too, so what the family record contains isn't something anybody holding an old link can change.

A timer nobody has to ask about

Start a feed or a sleep on your phone and it appears, already running, on every other phone in the household. The point isn't the stopwatch. It's that the other person can see it's happening now and doesn't have to interrupt to find out.

A running timer is shared between phones, so it's the one thing that needs a connection. Everything else can be logged offline and catch up later.

Coming back on duty

When you pick the phone up after a stretch of sleep, the dashboard opens with how the last few hours went: what was logged, by whom, and how the day is shaping up. You can mark that you've caught up, which is the small ceremony that stops the two of you re-reading the same night at each other.

What sharing isn't

It isn't a social feed. There is no public profile, no follower count and no way for anybody outside the household to see a child. A search engine can find the few pages about the app, like this one. The nursery behind the sign-in is closed to crawlers and to everyone who hasn't been invited.

And it stores the ordinary shape of a day (feeds, sleeps, nappies, meals, routines, notes) rather than anything clinical. What we keep, and what we measure.

Ready when you are

Sign in with your email, add your baby's name and date of birth, and you're logging. More children, other caregivers and your old history can all come later.
