A calm, private baby logbook built for 3am. Log one-handed, glance the day, and let LittleAi answer from your own baby's records. The record itself is free, always.
Little Logbook is a calm, private baby logbook built for the 3am feed: dark
by default, one-handed, and quick enough to use with a baby on your arm.
OUR STORY
Little Logbook exists because our own baby spent her first weeks in
neonatal care. Logging feeds between a hospital chair and the 3am feed at
home taught us what actually matters: one hand, no fuss, and honesty about
what the numbers can and cannot say. That is the app we built, and the one
we still use every day.
If your baby started in neonatal care (NICU or SCBU), you can tell the app
once in their profile and it quietly holds itself differently, starting
with tube feeds moved to the front of the feed screen.
THE LOGBOOK, FREE FOREVER
- Feeds (bottle, breast and expressing), nappies, growth, medicines, health
notes and milestones, each logged in a couple of taps
- Repeat the last feed with one tap, and see at a glance how long it has been
- Milestone photos and a shared family album
- Medicine and appointment reminders, with a month-at-a-glance calendar that
can mirror into your iPhone calendar
- Your baby's day drawn as a gentle rhythm, so patterns show themselves
- Works offline: log with no signal and it catches up later
- One logbook for the whole family: both parents, and a trusted nominee such
as a grandparent or nanny, each logging under their own name with one
family PIN
- Your data is yours: export everything whenever you like, and a real delete
that erases photos and records for good
LITTLE LOGBOOK PLUS
Plus is the part of the app that thinks about what you have logged. LittleAi
answers questions from your own baby's records rather than from the
internet, and it never gives medical advice: for anything worrying it points
you to your GP, NHS 111 or 999 straight away. Plus also includes the
Insights tab, the next-feed prediction, growth centile charts, weekly
development notes, the appointment summary and the weekly recap.
Built in the UK for UK families: nappies rather than diapers, health
visitors rather than paediatricians, and growth centiles from the RCPCH
UK-WHO references. Centile charts describe where a measurement sits; they
never diagnose.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Log with Siri. With your hands full, say "Hey Siri, log a feed in Little Logbook". Siri asks which feed, how much or how long, and when, saves it, and reads it back. Nappies, sleeps and expressing work the same way, even with your iPhone locked, and with no signal the entry waits on your phone and syncs when you next open the app.
Settings, Log with Siri lists everything Siri understands and shows how to make a shortcut so "Hey Siri, log a feed" works on its own. Needs iOS 18 or later.
