BubSync AI
Your 3 am brain, backed up by AI
One place for everything BubSync writes. Pick what you need, whether that is a plan for the day, your baby's sleep rhythm or play ideas, and it comes back grounded in your own logged days, ready to edit, keep, or pin where the next carer will see it.
A day schedule, written for today Premium
One timed plan for the day ahead: naps, feeds and play, generated from your baby's own logged pattern, and interwoven into a single schedule when more than one baby is along for the day.
Sleep rhythm, play ideas, milestones and insights Premium
Pick what you need and it is written from your baby's own logs. When there is not enough logged yet, it says so and gives age-banded guidance framed as general, never as your baby's own pattern.
Answers you can edit, keep and pin Premium
Every response streams in, opens in the same editor as your instruction manual, and can be saved to the family feed, or pinned above the timeline where the next carer will see it.
The welcome poem and the milestone prompts further down this page are AI as well, and both are free.
AI-generated schedules, summaries and suggestions are general guidance generated from your logged data. They are never medical advice.

A plan for Bub’s day, from her own recent pattern:
- 7:00 am — wake and a feed — Bub usually wakes hungry
- 9:15 am — first nap, likely around an hour for her
- 12:30 pm — a feed, then unhurried floor play
- 2:45 pm — afternoon nap may be due — watch for her tired cues
- 6:45 pm — bath and a calm wind-down toward the night sleep

Sample output — in the app, every response is generated live from your own logged timeline, and you can edit it before you keep it.

The moments you'll want to keep

A poem, just for them
The moment you welcome a new baby, BubSync writes them a short poem of their own. Keep it in their memories and it stays there for good.
Hello, little one,
the world held its breath

Handing over
Brief the sitter without the phone call
Most trackers stop at the people who have the app. The person who turns up at seven to watch your baby usually does not, and never will for one evening.
Send a link, not an essay
Send a handover as a link that opens in any browser for 24 hours. The person you send it to needs no account and no app.
Write it down once
Write your care essentials and instruction manual once: comforts and likes, sensitivities and dislikes, and how you do things.
Give a sitter one baby, not your whole family
An invite asks who the person is: a parent, family, a carer, or a mix you pick yourself. They see what someone in that role should see, for the babies you chose, without you configuring anything.
Premium adds live shared care: invite a partner, grandparent or carer into the family so the handover keeps updating instead of freezing at the moment you sent it. Sent, delivered and seen, for every device in the family. You can tell whether the 3 am feed reached your partner before you go back to sleep. See how sharing and handovers work.
Quick answers
Start with the baby tracker question you need answered
Searchers usually want one of three things first: a feeding tracker, a sleep tracker, or a shared-care app. These guides answer those questions directly.
Baby feeding tracker
What to log for every feed, how many feeds a day is normal by age, and how to bring a clear record to your next health check.
Read the guideBaby sleep tracker
What to log for naps and nights, how wake windows change by age, and how to tell a rough week from a real sleep regression.
Read the guideBreastfeeding log
Which side was last, and how long since the last feed. What to record in a breastfeeding log, what to skip, and how to read a week of it.
Read the guideBreastfeeding reminder
When a breastfeeding alarm genuinely helps, when it does more harm than good, and how to set reminders that follow the baby, not the clock.

Our story
We built the baby tracker we needed at 3 am
Hi, I'm Ashley. I'm a software engineer, a dad of two (nearly three), and one half of the family behind BubSync. Sarah and I built it in Brisbane, between night feeds, early mornings and full-time work, because the apps we tried didn't fit the way real families share the care of a baby.
When our youngest daughter was born, Sarah was on maternity leave and I was working full time. We split the nights the way a lot of couples do: Sarah took the late nights, and I took the early mornings so she could finally get some unbroken sleep.
That split has a gap right in the middle of it. When I got up at 3 am to settle our daughter, I didn't know when she'd last been fed, when her nappy was last changed, or how long she'd been asleep. The one person who knew was the one person I was trying hardest not to wake.
