Voice logging

The best interface at 3am is not looking at your phone.

Switch voice on in Settings, then tap the mic on Today and say “log a four ounce bottle”. It listens for 30 seconds, reads back what it heard, and waits for you to say confirm. One tap, then eyes back on your baby.

Say it however you say it

Twenty-five things you can say, in the words you'd use.

These are not suggestions. Every line below is a case the parser is tested against, including the one with the “um”. The two marked Plus log only with Plus; on the free plan, voice says so and logs nothing.

“log a four ounce bottle”
“log a bottle, four and a half ounces”
“she took 6 oz”
“log her usual bottle”
“bottle, the usual”
“log a 4 oz bottle of formula”
“4 oz breast milk”
“log 120 ml bottle”
“bottle two ounces an hour ago”
“bottle at 3, four ounces”
“wet diaper”
“log a poopy diaper, medium amount”
“wet and poopy diaper”
“a big poopy diaper”
“blowout”
“she took a number two”
“changed her diaper”
“baby's down”
“down for a nap”
“she's awake”
“she woke up”
“pumped four ounces”Plus
“bath time”Plus
“4 oz bottle, she spit up”
“Um, uh, log a wet diaper”

What voice logs

Bottles, diapers and sleep, free. Pumping and baths too, with Plus; on the free plan it says so and logs nothing. Nursing, growth, solids and medicines are not spoken. They are a tap in the app, and nursing can also go through Siri, as can medicines with Plus.

Common phrasings are matched by an on-device grammar, which is why they are instant. On iPhones with Apple Intelligence, anything unusual falls back to Apple's on-device language model. The grammar runs first on purpose: at 3am the usual sentence has to be immediate and certain, and putting the model first would make the common case slower in exchange for nothing.

Voice is off until you switch it on, and even then the microphone opens only when you tap it: 30 seconds at a time, with a ring counting down, and only while Beacon Baby is open. With the phone locked, Siri is the way in.

When it gets it wrong

Six behaviors that make a misfire cheap.

A voice feature that occasionally logs a feed that never happened is worse than no voice feature at all. So every one of these exists to make a mistake cost you one tap.

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.

“No wait, that's not right” is never a yes

The parser treats rejections as rejections. Talking to the room while the mic is open cannot accidentally confirm a draft.

It listens only when you tap, and stops by itself

Tap the mic and it listens for 30 seconds, with a ring counting down and a waveform while it hears you. If it is waiting for your “confirm”, the 30 seconds start again; otherwise it closes. Nothing listens in the background.

Nothing is recorded, ever

Speech is transcribed by Apple's on-device recognizer. Audio is not stored and not sent to any server, including ours.

Through Siri

Or never open the app at all.

Beacon Baby ships native App Intents, so logging works from the lock screen, the Action Button, or a Shortcut. Phone on the arm of the chair; baby still asleep.

When Siri logs something it answers “Logged.” — or “Sleep ended.” when you end a sleep — and nothing more; it never reads an amount back to a locked phone. If you don't say which kind of diaper or which side, Siri asks, and a medicine has to be in your cabinet in the app before Siri can log it. Ending a sleep or a feed, or hearing today's summary, asks for Face ID first, because each one tells whoever is holding the phone something about your night. On the free plan, pumping and baths get “Logging pumping is part of Beacon Baby Plus. Nothing was logged.” and nothing is written.

A bottle logged through Siri is recorded as 4 oz. If it was a different amount, fix it with a tap in the app.

A listening app that sends nothing anywhere.

Voice assistants often send audio to a server. Beacon Baby's voice does not: speech is transcribed by Apple's on-device recognizer, audio is never written to disk, and it is never sent anywhere, including to the server that sharing uses.

The app’s own wording, verbatim: “Speech is transcribed on this device. Nothing is recorded or sent.”

Try saying it out loud once.

It feels faintly ridiculous the first time and completely normal by the second night.
