Baby Duo

Baby Duo is a newborn routine log built for four in the morning.

One tap and it's done: the feed, the diaper or the nap is logged. No forms, no menus, no waiting for anything to load. If you need to fix the time or note the millilitres, hold the button and the detail sheet opens.

SLEEP
The night you don't remember, worked out from the feeds you did log. In the morning the Sleep tab shows the stretches your baby slept, and you confirm them with one tap — nothing is saved unless you look at it first. Daytime naps are asked, not assumed: a gap between feeds in the daytime doesn't mean they slept the whole time.

Once there are enough sleep stretches of their own, it works out when the next nap is due — from your baby's rhythm, not from a table for their age. Until there are, it says so. The card comes in four shapes; pick the one you read best.

The Sleep tab comes with Plus. Logging sleep, and confirming the night, is free.

MULTIPLE BABIES
With twins, or with a second child, each one has their own history and their own metrics. Switch between them from the top, in one tap. With a single baby nothing appears: the screen stays exactly as it was.

The first baby is free. Adding a second one comes with Plus.

BOTH OF YOU SEE THE SAME THING
There are no two histories to reconcile. It doesn't matter who logged it: the information belongs to the family and syncs on its own. Your partner sees the 4am feed without anyone having to recount the night.

WORKS WITH NO SIGNAL
Everything is saved on the phone first. In a basement, on a plane or with no bars, logging still costs one tap, and what you logged uploads once the network is back.

FROM THE HOME SCREEN
The widget shows how long since the last feed, with buttons that log without opening the app. On the Lock Screen, a ring fills toward the next expected feed. And while the baby sleeps, a Live Activity counts on its own.

ON YOUR WRIST
The Apple Watch app logs a feed, a diaper or a sleep from the watch, and the complication keeps the last feed on your watch face. It is free, and it needs no account of its own: it reads from the paired iPhone.

WHAT YOU CAN LOG
- Feeds: left breast, right breast or bottle, with a stopwatch or millilitres
- Diapers: pee, poo or mixed
- Sleep: the same button opens the stretch and closes it
- Bath, medication and weight

THE HISTORY, WITHOUT A LONG SCROLL
Past days come collapsed, with a summary of what happened that day — how many feeds, how many diapers, how many sleeps — and open with one tap.

THE WEEK AT A GLANCE
Feeds per day, average interval between feeds, hours of sleep and diaper counts. Sleep stretches that cross midnight are split across both days, so the bars don't lie.

GUIDES
Eight short guides on the first weeks: how much milk by age, what diapers look like week by week, the milestones of year one, what to pack in the bag, and three on US hospital checks and checkups. Every figure says which public source it comes from, and every guide carries its disclaimer: they do not replace your pediatrician.

The warning signs guide — what never to do and when to call — is free. The other seven come with Plus.
