iPhone Duo
Open it, and the day spreads out.
Closed, it is the phone you know. Open, the cards sit two by two across the wide inner screen and the tabs move to the side, where your thumb already is.
A baby tracker for newborns and infants, on iPhone, iPad and Apple Watch
Track your baby's feeds, sleep, diapers and growth.
Hold the button and say “120 ml, left side” — Baby Memos fills in the record for you. Or tap it in instead. No account needed.
What you log
Everything that happens in a day has somewhere to go.
Fourteen built-in types, in the same colours the app paints them. Missing one? Make your own.
06:30
Log it with one hand full.
Hold the green button and say it out loud. Let go, and a card appears with the record already filled in — glance at it, save it. Recognition runs on Apple's own speech engine, in all fourteen languages.
“He had 120 ml of formula”
Bottle 120 ml · Formula · 06:30
- Mumbled it? Nothing is lost — anything it can't classify is kept as a note, in your own words.
- Rather not talk? The quick panel is one tap away, and any record is two taps from there.
- Bottle, breast, sleep and pumping can run a timer that keeps ticking on the Lock Screen and in the Dynamic Island.
13:20
“When did he go down last night?”
Every record, newest first. Filter to one type, jump to a date, edit anything. Put a future date on a record and it turns into the next appointment, pinned to the top of the list.
15:05
Day after day, side by side.
The whole day stood on end, midnight at the top and midnight at the bottom. Put a few days beside each other and the shape of a routine shows up on its own — the night getting longer, the naps settling.
- Sleep is drawn as a band, so a night and a catnap never look alike.
- Filter to one type to ask a narrower question.
- Three views: Today spells out every entry, Compact fits a whole week on one screen, and Pro marks each entry with what matters most — volume, sleep quality, stool colour.
One day, start to finish Hover a mark

The numbers do the talking.
Each type keeps its own page: today's count, this week's daily totals, where the trend is heading. Weight, height and head size land straight on the WHO growth standards — birth to five years, separate curves for boys and girls — with the percentile spelled out.
- A sleep that crosses midnight is split at 00:00 and counted into both days.
- Metric or imperial, switch any time.

Made for iPhone Duo.
Made for iPhone Duo.
At home on every Apple device.
Built natively for iPhone, iPad and Apple Watch — the same records, on whichever screen is closest to hand.
iPad
The one on the sofa.
Everything the iPhone app does, on the big screen. With family sync, what you log on the iPad shows up on everyone's phone.
Apple Watch
Both hands full, one glance.
The last feed and the last diaper, right on your wrist. With Premium, log the next one there too, without putting the baby down.
Also in the box
The quiet half.
Vaccines, and a reference to read
Log the shot he just had, or type in one that isn't listed. Date it in the future and it becomes the next appointment. The reference is read-only and stays out of your records.
Lock Screen and Home Screen widgets
Seventeen of them. The seven round ones on the Lock Screen log a feed, a sleep or a diaper in a single tap — the app never opens.
A timer in the Dynamic Island
Start a bottle, breast, sleep or pumping timer and it keeps running on the Lock Screen, with separate left and right sides for nursing.
It backs itself up
Once a day everything is backed up, photos included, to your own iCloud Drive. On a new phone it all comes back in one go.
Fourteen languages
English, 简体中文, 繁體中文, 日本語, 한국어, Português, Français, Español, Deutsch, Русский, Italiano, Nederlands, Türkçe, Polski — for the interface and for the voice recognition alike.
Built for VoiceOver
Every button tells VoiceOver what it does, text follows the size you set in Settings, and the animations settle down when Reduce Motion is on. iOS 17 or later; watchOS 11 or later.
21:30
No account. Just the people in the room.
No sign-up, no email, no Apple ID. One device makes a one-time invite code, the others type it in, and from then on whatever anyone logs shows up on everyone's phone.
- The moment you write it down it is on your phone. On everyone else's, a moment later.
- You are not the only one writing it down — whatever anyone in the family logs lands in the same place.
- You choose who is in the family, and you can take someone out again at any time.

Your records live on your phone.
No sign-up, no login. Install it and start logging.
- Where it lives
- Everything you write stays on this iPhone. Unless you turn on family sync, it never goes anywhere else.
- Once family sync is on
- What you write shows up on your family's phones within seconds, and what they write shows up on yours.
- Backups
- Once a day everything is backed up, encrypted, to your own iCloud Drive. You can put a copy wherever you like, whenever you like.
- Ads
- No ads, and nothing in the app that is there to show them.
