The thing in the way
Nobody tells you the clipboard comes home with the baby.
The paperwork nobody puts on the registry. It ends up living in one person's head — and the apps on the registry list either want twelve taps a feed or want to grade your baby.
From the first days, you'll be asked.
How often is she feeding? How many wet and dirty diapers? It's asked before you leave the hospital and again at the first visit a few days later — while every registry list recommends a different app.
If nothing changes: No system, and sticky notes on the fridge by night three.
Nobody wants to be the one who doesn't know.
Or the one who carries all of it. When the day lives in one person's head, everyone else has to ask them — mid-handoff, at 3am — and the answer is “I think so? Around one?”
If nothing changes: One of you becomes the household's memory, and the other has to ask.
It's a two-person job.
Keeping track of a newborn is a two-person job, and it shouldn't take more than a second. Tracking is worth doing; it just has to cost seconds, not evenings.
If nothing changes: A twelve-tap app, abandoned in week one.
Tracking is worth doing. It should just cost you seconds, not evenings.
Why it lasts past week one
Four things that make it a two-second job.
One tap, one log for everyone, nursing as well as bottles, and a screen that stays dark at night. There are nineteen more, and every one of them is on the features page.
One tap, and it already knows the amount
The bottle button arrives pre-loaded with what you usually give at this hour, so the common case is a single thumb press with no numbers to enter.
How: Plain arithmetic over your own history — the median of what you have logged at this hour before. No model, no advice, no other family's data.
Bottle, breast, or both
Tell Beacon Baby how you feed and the Today screen changes to match: ounces to log, or a timer and which side, or both one tap apart.
How: A feed at the breast has no amount to record, so the amount control is replaced by a timer rather than left there asking for a number that doesn't exist.
A screen that doesn't wake the room
Night mode switches the whole app to a real dark palette between 7pm and 7am — not a gray filter over a white app, so a 3am log doesn't blind you or the baby you just got down.
How: It is the default Auto appearance: dark from seven to seven, or whenever your iPhone is in dark mode. The log colors are retuned for the dark, and a soft dim sits over the whole app at night — hold anywhere to lift it for as long as you need. It never changes your iPhone's brightness setting.
Everyone who helps, one log
Invite a partner, a grandparent or a nanny from the Family tab, and everyone sees the same feeds, changes and sleeps as they happen. Choose whether each person can manage the family, log care, or only view, and which children they see. Off until you switch it on — and until you do, nothing about you or your baby leaves your phone. Free, for as many people as you invite.
How: Sign in with Apple, or with an emailed link or 8-digit code, then invite someone with a six-character code that works once and ends in 24 hours. Every row is keyed to a household and the database refuses any request for one you are not in, which is enforced underneath the app rather than by it asking nicely. A view-only phone uploads nothing. Photos never sync.
Free covers the whole 3am job — logging, voice, Siri, the watch, undo, reminders, partner sharing with roles, care summaries, export, and the last seven days of trends. See what Plus adds.
Who made this
We built it on the nights we needed it.
We built Beacon Baby at 3am, one-handed, in the dark, with a baby in the other arm. Twice. Every shortcut in it exists because we needed it that night — and the sharing exists because two of us were asking each other the same three questions.
One hand, in the dark
Every feed, diaper and nap is one tap on a full-width card your thumb learns once. Confirmation is a short buzz, not a dialog. The app's written brief is “one hand, 3am, baby in the other arm, lights off.”
Free to log and share, forever
Logging, voice, the Apple Watch, reminders and sharing with everyone who helps are free, and the free tier never expires. Plus is optional, for extras like longer trends and a second child.
No verdicts, and nothing leaves your phone until you share
Nothing is labeled “low” or “concerning” — it is a log, not a monitor. And until you turn on sharing, there is no account and nothing you record leaves your phone.
The plan
Ready in three steps — two of them before she's born.
No migration, no import, no setup call. Do the first two on a quiet weekend; the third is the only one that happens at 3am.
- 01
Set it up this weekend
Install it and add your due date — or her birthday, if she's already here. Then pick how you'll feed in Settings. Two minutes, and no account needed.
- 02
Invite each other
One of you signs in and sets up sharing on the Family tab, then sends an invite code. Partner, grandparent, nanny — everyone sees the same log, with who logged what.
- 03
Tap from day one
Every feed, diaper and nap is one tap — or one sentence, once you switch voice on — on whichever phone is closest.
What it looks like
Two weeks in, nobody is the memory.
It's on both phones before the car seat is in
Set up on a quiet weekend, so the first entry is a tap rather than an install.
Whoever's awake taps once
A feed, a change, a nap — one tap on the nearest phone, and everyone's screen has it.
The first visit is a hand-over, not a quiz
Hand over the phone, or the one-page visit report of the last two weeks.
Handoffs take seconds
No debrief, no “wait, did you?” — the day is on the screen, and so is who logged it.
From nervous first-timers hoping to remember it all to a team that came home ready.
What Beacon Baby is.
Beacon Baby is a baby tracker for iPhone and Apple Watch. It logs bottles, nursing, diapers, sleep, growth and solids in one tap, and shares one log with everyone who helps — each entry saying who logged it. It makes a care summary and a one-page visit report to hand over at a visit. It never tells you a number is low or high: it is a log, not a monitor. Logging and sharing are free, forever.
The part nobody warns you about
Somebody is going to ask you. The first time is in the first few days.
Not eventually, and not in general terms. Before you leave the hospital, and again at the first checkup a few days after you get home, someone will ask how your baby has been feeding — and by then the days have already stopped being separate.
The first few days
- “How often is she feeding?”
- “How many wet and dirty diapers?”
Often asked before you leave the hospital, and again at the first visit a few days later.
At about one month
- “How has the feeding been going since we last met?”
- “What does sleep look like — what is the longest stretch?”
Now they want a trend rather than a snapshot, which is exactly the thing memory cannot supply.
At about two months
- “Any change in how much she is taking?”
- “How are the nights, and how are you?”
By here the days have blurred completely, and the only reliable witness is whatever you wrote down.
You will not be in trouble for not knowing. You will just spend the appointment guessing — about a question you could have answered exactly, by handing over the phone.
Say it instead
Your hands are full. Talk to it.
Tap the mic and say a real sentence. It listens for 30 seconds, reads back what it heard, and waits for you to say confirm — the same shape as the app, running a port of the app's own grammar.
Not listening
Tap, then say “log a four ounce bottle”
Your browser has no speech recognizer, so this demo types the phrase instead of listening. In the app, speech is transcribed on-device by Apple's recognizer and audio is never recorded or transmitted.
- “log a four ounce bottle”
- “she took 6 oz”
- “wet and poopy diaper”
- “log a diaper”
- “blowout”
- “baby's down”
It reads back before it commits
Beacon Baby says what it heard — “Log 4 ounce bottle. Confirm?” — and waits. Say “confirm” or tap Save. Nothing is written on the strength of one pass at your voice.
It admits when it missed
If the phrase isn't one it knows, you get “Didn't catch that” with the transcript, not a guess. A wrong log is more expensive than no log.
No amount heard is called out
Say “log a bottle” with no number and the draft starts at a placeholder 3 oz, marked “No amount heard — check this before saving.” Nothing is saved until you set the amount or confirm it.

View allFree printable
Bring the baby home with a plan, not a pile of apps.
Three printable pages for the week before and the week after: somewhere to write down the first days, a setup checklist for both your phones, and a plan for who covers which night. Free, and yours to keep whether or not you ever use the app.
- The first-week log: a page a day for feeds, diapers and sleep — the things you'll commonly be asked about at the first checkups.
- The before-baby setup checklist: what to put where, and which phone does what, before the bag is by the door.
- The partner handoff plan: who covers which night, and what the person coming on shift needs to know.
The Day-One Kit
The agreement
Four things we will never do.
Not values on a wall — constraints in the build. Sharing is the one thing that moves your log off your phone, it is off until you switch it on, and we say exactly what it does when you do.
We will never tell you a number is low, high, or concerning. It is your log, not our diagnosis.
We will never charge you to log a feed, a diaper or a sleep, or to share the log with the people who help.
We will never turn on sharing for you. Until you do, nothing you record leaves your phone.
We will never show you an ad, and we will never sell what you log.
Pricing
The 3am part is free. Forever.
Everything you use at 3am stays free — logging, voice, undo, export and sharing. Plus is for the rest of the story: a second child, a season of trends, and the firsts worth keeping.

Upgrade inside the app, any time
Plus starts with a 7-day free trial if your Apple ID hasn't had one. The free trial converts to a paid subscription unless it is cancelled at least 24 hours before it ends. Payment is charged to your Apple ID at confirmation. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID settings. Nothing you have logged is ever taken away — if a subscription lapses, your entries stay on your device and stay exportable.
Straight answers
Thirteen questions, honestly answered.
The first six are the ones expecting parents ask. None of it is medical advice.
Before she arrives
What expecting parents ask before they install anything.
When should we set it up?
Before you need it — a quiet weekend in the last few weeks is plenty. Install it and add your due date (the first screen says “Not here yet? Choose the due date.”), pick how you'll feed in Settings, and set up sharing if you want it. It takes about two minutes. On the day, change the date to her birthday in Family → Children.
Can my partner use it on their phone?
Yes, for free. One of you signs in — with Apple, or with an email that sends a link and an 8-digit code — sets up sharing on the Family tab and invites the other with a six-character code that works once and ends in 24 hours. After that every phone you invite sees the same log as it happens, and each entry says who logged it. A grandparent or a nanny can join the same way, set to log care or only to view.
Is it really free?
Yes, and the free tier never expires. Logging feeds, nursing, diapers, sleep, growth and solids, voice, Siri, the Apple Watch, reminders, the care summary, the last seven days of trends, and sharing with everyone who helps are all free. Plus is optional: it adds longer trends, more than one child and extra trackers such as medicines and photos, and starts with a 7-day free trial if your Apple ID hasn't had one.
Will it tell us if something's wrong?
No. Beacon Baby is a log, not a monitor: it records what you tell it and never labels a number low, high or concerning. If anything about your baby worries you, call your pediatrician rather than waiting on an app.
Does it work for nursing?
Yes. Choose nursing, or both, in Settings → Today screen → How you feed, and Today shows a timer and which side instead of an amount. Nursing is free. Log it with a tap or through Siri; the in-app voice logs bottles, diapers and sleep rather than nursing.
Twins, or a second child?
A second child is part of Plus. One child is free; with Plus you add more from the Family tab, each with their own name and their own log. Children sync over sharing, so everyone you share the log with sees them. If Plus lapses, children you have added stay and can still be logged, and adding another one needs Plus again.
What you're actually wondering
None of this is medical advice, and none of it is a diagnosis. Your pediatrician is the authority on your baby.
How many ounces should a newborn be eating?
This is the most-searched question of the first month, and the honest answer is that no website can tell you. Published guidance from bodies like the AAP is written as wide ranges that move with a baby's weight, age, and growth — and your pediatrician is the only person who has all three. What you can know is what your own baby actually took, across an ordinary week, and whether that has shifted. That is the number worth having at the two-week visit, and it is the one a log gives you.
How do I know if my baby is getting enough?
That is a clinical judgment. It needs a scale, a growth curve, and an examination, which is why weight checks exist and why Beacon Baby does not attempt it. What a log changes is the quality of the conversation: it turns “I think she has been feeding less?” into a week of actual entries someone qualified can read. If you are worried tonight, call your pediatrician rather than opening an app.
What will the pediatrician actually ask me?
Feeding, output, and sleep, roughly in that order, and usually as “how has she been eating?” rather than as a form. The AAP’s Bright Futures schedule puts the first visit at 3 to 5 days old, usually within a few days of coming home, then about one month and two months. The early visits are mostly feeding and weight; by two months, sleep and how the days are going come up too. Having the last week in front of you turns the appointment from a quiz you did not study for into a conversation.
About Beacon Baby
The four that decide whether it is worth your first night.
Does my baby's data leave my phone?
Not unless you turn on sharing, which is off until you do. On a default install there is no account, no analytics and no advertising SDK, and everything you log stays on your device — the app's own Account and sync screen, under Family, calls this state “Off. Nothing leaves this device.” Turning sharing on copies your entries to our database so everyone you invite sees one log; it needs a sign-in, your household is isolated at the database level, and photos never sync. With sharing off, the app contacts nothing when it opens.
Do I have to create an account?
Not to use it. There is no sign-up, no email and no password — the first screen asks for your baby's name and date of birth, and you can start logging in under ten seconds. The only thing that needs an account is sharing a log with your family, which is optional and off until you switch it on. You can sign in with Apple there — and choose Apple's Hide My Email if you would rather we never saw your real address — or with an email that sends a link and an 8-digit code.
How does the voice logging work?
Voice is off until you switch it on in Settings. After that, tap the mic on Today and say “log a four ounce bottle”. It listens for 30 seconds, with a ring counting down, then reads back what it heard and waits for you to say “confirm” or tap Save. It logs bottles, diapers and sleep by voice, free. Pumping and baths by voice are part of Plus; on the free plan it says so and logs nothing. Common phrasings are matched by an on-device grammar so they are instant; anything unusual falls back to Apple Intelligence on the phone, where available. Speech is transcribed by Apple's on-device recognizer, which needs a one-time download of Apple's speech model. Audio is never recorded and never sent to a server, including ours. Nothing listens until you tap; from a locked phone, use Siri.
What do I need to run it?
An iPhone running iOS 26 or later. There is an Apple Watch app included for watchOS 26 or later, which logs a bottle, a wet diaper, or the start or end of a nap in one tap; each tap is logged when your iPhone app next receives it. Portrait only on purpose — a landscape layout is one more thing to get wrong at 3am — and there is no iPad, Android, or web version. The app is in English.
Set it up before you need it.
Two minutes now is two minutes you don't spend at 3am.
Free to log, forever. No account needed to log. iPhone, iOS 26 or later.
