Log everything, fast
Feeds, sleep, nappies, potty, pumping, medicine, activities, growth, temperature and symptoms, all one tap from the home screen, timers included.
Baby tracking, without the busywork
Every feed, nap and nappy tracked together, so you're never left guessing.
Cubby is the shared log for you and everyone who helps look after your baby. Log something in one tap, watch patterns emerge on their own, and get predictions built from your baby's own history, not a generic chart.
Free to use, for every caregiver in your family · Cubby Plus adds even more
What makes Cubby different
Most baby apps only solve one of these. Cubby brings them all together.
One app, not four
Feeds, sleep, nappies, potty, pumping, medicine, activities, growth, temperature, symptoms, vaccines and milestones all live in the same app, not spread across separate trackers you have to keep switching between.
Predictions from your baby, not a chart
Most apps hand you a generic age-based schedule. Cubby learns from your own baby's actual history instead, getting to know them a little better every time you log something.
Room for everyone who helps out
A grandparent or nanny can have their own login and their own place in the family, seeing and logging exactly like anyone else, or be added without one if that's simpler. Link two households together for a blended family too, all staying in sync in real time.
One Plus, the whole family
Cubby Plus is priced per family, not per person. Everyone caring for your baby is covered from one subscription instead of being billed separately, the way most apps do it, and it even follows you personally across two households if you're helping out in both.
Features
One tap to log, zero effort to understand
Nappy detail, down to the shart
Size, colour and consistency, as precise as you need, right down to "Shart" for when it's really more of a poopy fart than a proper poo. We asked around, apparently it's a real gap in other apps.
Built for the whole family
Every caregiver, a parent, a grandparent, a nanny, can have their own login and their own place on the shared timeline, or be added without one if that's simpler. Everyone stays in sync in real time.
A friendly leaderboard
See who's logged the most today, this week or this month, medals for the top three, plus a breakdown by feed, sleep, nappy and more. Share it with the family in one tap.
Blended families welcome
Link two households, like co-parents living apart, so a shared child's data stays in sync between both, without merging everything else.
Predictions from real history
Next feed, next nap, wake windows: all estimated from your own baby's actual patterns, not a one-size-fits-all schedule.
Shows its work, not just a guess
Every prediction breaks down into the exact numbers behind it, your baby's own recent average blended with the norm for their age, right there on screen. Not a black box.
A broken night, still one sleep
Woke for ten minutes then went back down? Cubby links the two back into one sleep automatically, or by hand if the gap's unusual, instead of leaving you with three separate entries to make sense of.
Medicine that reminds itself
Set a dose and interval once. Cubby tracks when the next one's due and nudges you, so you're not doing the maths at 2am.
A clearer picture when they're unwell
Log fever, cough, rash and more together, with a severity for each, since a poorly baby usually has several at once. See the pattern on a chart instead of piecing it together from memory.
Your region's vaccine schedule
UK, Ireland, Australia, the US and Canada schedules built in, matched to your baby's own age automatically, with room to add your own custom doses on top.
Every milestone, not just the big ones
First smile to first sentence, motor skills to social ones, across five categories covering the whole of early childhood, not just a highlight reel.
Never lose track of new foods
Track all nine major allergens and exactly when each one first appeared on the menu, right alongside every other feed you've logged.
Gentle nudges, not noise
A quiet reminder before the next nap window, or a medicine dose due. Never a badge count you have to fight.
Ready for the doctor
Export a clean PDF or CSV of any date range in one tap. No scrolling through the app in the waiting room.
The Day Ring
Your baby's whole day, in one glance
Four nested rings (sleep, feeds, nappies, and everything else) fill in as an open horseshoe as the day happens, not a closed circle. It's the one screen that answers “how's today actually going?” without reading a single number, and it's built right into the home screen.
Insights
Patterns you'd never spot at 3am
Cubby quietly builds a picture of your baby's real rhythm: feed timing, nap trends, wake windows, all surfaced as charts you can actually read in ten seconds, not a spreadsheet you have to build yourself.
- Weekly comparisons for feeds, sleep, nappies and more, side by side
- Growth charted against WHO percentiles, tap any point for the exact numbers
- A symptom log turned into a frequency chart, so a pattern shows itself
- A full daily and weekly recap, built automatically
Cubby Plus
Free covers a lot. Plus covers the rest.
Every caregiver already gets a lot for free: every log type, predictions, vaccines, milestones, no catch. Cubby Plus is one extra subscription for the whole family, priced per family rather than per person, so once someone subscribes, everyone gets the full experience.
The big one
One payment, the whole family
However many caregivers are logging in, everyone gets Plus the moment one person subscribes. No extra seats, no per-user add-on like most apps charge for a second parent's phone.
Show, don't tell
Live Activities on your Lock Screen
A running sleep or feed timer shows right on the Lock Screen and in the Dynamic Island, so you can glance at it instead of unlocking the app to check.
✓
Push reminders before the next nap
A quiet nudge shortly before your baby's usual wake window ends, so you're not the one watching the clock.
✓
Advanced insights & predictions
Growth velocity, sleep-pattern views and prediction-accuracy checks on top of the free charts, for a deeper read on your baby's own history than the basics give you.
✓
Follows you, not just a family
A grandparent helping out across two households stays Plus in both, without ever paying for it twice.
✓
Apple Watch app
A full hero card on your wrist: nap, night sleep or awake at a glance, one-tap logging, and a face complication for status without opening the app at all.
✓
Quick combos
Set up the things you log together (a bottle plus two medicines, say) as one combo, then fire the whole routine in a single tap from the quick-log grid or your Watch, instead of logging each one separately.
Coming soon
Home and lock screen widgets
See what's running and what's due next without opening the app at all.
About
Why we built Cubby
We're first-time parents, and Cubby started from a real problem: late at night, early in the morning, or handing off to each other mid-day, neither of us wanted to rely on memory for what already happened. We wanted one place we could both check and both trust.
We tried the other baby-tracking apps first. Most were either expensive, or convinced they knew better than us, pushing a “better” nap schedule, or worse, offering to sell us a fix for one. Our own baby naps in short 30-minute stretches. That's not a problem, it's just how our baby naps, and we wanted an app that tracked it, not one trying to change it.
One of us is a data engineer, so the numbers underneath get real attention: growth velocity, sleep-pattern breakdowns, prediction accuracy, not just a headline stat. If that's more depth than you want, Advanced Insights has its own switch to turn it off, and Cubby still just quietly tracks either way.
Estimates and insights in Cubby are for your own tracking, not medical advice. Every baby is different, so trust your own judgement, and check with your doctor for anything you're concerned about.

Cubby is free to use, with Cubby Plus available if you want more. It's still in testing ahead of its full launch, so request early access below and we'll get you set up.
Cubby's still in testing ahead of its App Store launch, so early access happens through TestFlight, Apple's own beta-testing app that's free from the App Store. Add your Apple ID email below and we'll send a TestFlight invite to it by email: accept the invite, install TestFlight if you don't have it already, and Cubby installs from there like any other app.
