Half Pint: Baby Tracker & Log

Half Pint is a baby tracker for the two people doing the 4am feeds.

Feeds, sleep, diapers and pumping, logged in one tap with one hand. Everything you enter lands on the other parent's phone within seconds. Nothing you log ever leaves your own iCloud.

BUILT FOR THE NIGHT

From 8pm the whole app turns amber on black. Not a dark mode: a different screen, with the time, how long she has been down, one huge button and nothing else. Warm light leaves your eyes adjusted to the dark, so you can log a feed at 3am without waking properly, and without waking anyone else.

Stopping a feed at night just logs it. Nobody chooses left or right at 3am, so the details wait until morning. Nothing predictive is allowed to buzz between 8pm and 6am.

BOTH PARENTS, ONE PICTURE

Start a feed and it appears on your partner's lock screen as a live timer, counting. Stop it and theirs stops too. When one of you logs something overnight, the other gets a silent alert waiting in the morning.

Setting it up is one link. No account, no invite code, no server in the middle. It is an iCloud share between your phones, and you can revoke it whenever you like.

WITHOUT OPENING THE APP

- Live Activities and the Dynamic Island for a running feed, sleep or pump
- Home screen and lock screen widgets with the last feed and the next one due
- Quick log buttons right on the widget
- Siri, Control Center and the Action Button
- Notification actions that stop a timer without unlocking

WHAT IT TRACKS

- Feeds: breast, bottle or both, timed or added afterwards. A top-off within twenty minutes joins the feed before it instead of starting a new one
- Sleep: naps and nights, with a sleep view that treats 7pm to 7am as one night so bedtime and the long stretch stay together
- Diapers: one tap for wet or dirty, a running count of what is left in the drawer, and a nudge before you run out
- Pumping: its own timer, running alongside a feed, ounces to the quarter
- Growth: weight and length against WHO percentiles
- Health: temperature with a fever flag, medicines with the last dose
- Solids: first foods with allergen notes and reactions

MAKING SENSE OF IT

A plain-words recap of the last twelve hours, written from your own entries, that tells you whether last night was actually worse than the one before or only felt like it. A day at a glance. Seven-day trends. A calendar back to your first entry. CSV export of every row you have ever logged.

PRIVACY

Half Pint has no server. Your entries live in your own iCloud account, shared only with the people you invite.

- No ads, no analytics, no trackers, no third-party SDKs
- No account to create and nothing to sign up for
- The recap is written on your phone, not on a server
- Free, with no subscription and no in-app purchases

Half Pint is not medical advice and it is not a monitor. If you are worried about your baby, call someone who can help.

Requires an iPhone running iOS 18 or later, signed in to iCloud.
