A calmer way to keep up with your baby’s days.
Track feeds, sleep, and diapers in a single tap — with corrected-age support for preemies, gentle reminders, and a design made to feel calm at 3am. Works offline, syncs when you’re back.
The days start to blur together.
Feeds, naps, changes, repeat. Then the question every tired parent knows — wait, when did she last eat?
Lumi keeps the quiet count for you, so you can stop holding it all in your head — and just be there.
Everything you need. Nothing you don’t.
Five things Lumi does quietly well — so tracking never becomes another thing to manage.
Effortless tracking
Feeds, sleep, and diapers in a single tap. One-handed, at 3am, without thinking.
Made for preemies
Corrected-age support built in, so ranges and milestones reflect your baby’s real journey.
Works offline
Log anywhere — the nursery, the car, a dead-zone clinic. Lumi syncs the moment you’re back.
Gentle reminders
A soft nudge when it helps, never a nag. You set the rhythm; Lumi keeps it.
Calm & ad-free
No ads, no clutter, no upsells. Just a quiet space for the two of you.

Questions, answered gently.
Is Lumi free?
Yes — Lumi launches free with all the core tracking you need. If we ever add extras they’ll be optional, and there are no ads either way.
Does it work offline?
Completely. Log anywhere — Lumi keeps entries on your device and syncs them automatically the moment you’re back online.
Is my data private?
Your baby’s data belongs to you. We never sell it, we ask for as little as possible, and it’s used only to power the features you choose to use.
Does Lumi support preemies and corrected age?
Yes. Add a due date and Lumi tracks corrected age alongside actual age, so ranges and milestones reflect your baby’s real journey.
Which platforms will it be on?
iOS and Android at launch. Join the waitlist and you’ll be among the first to know when each is ready.
What can I track?
Feeds (nursing, bottle, and solids), sleep, diapers, pumping, medicine, growth and more — each with its own gentle color so the day is easy to read.
Can I track more than one child?
Yes — switch between siblings in a single tap, each with their own timeline and settings.
When does Lumi launch?
Soon — we’d rather get it calm and right than rush it. The waitlist hears the moment it’s ready.
Be there when Lumi opens.
One gentle email the day it’s ready — and nothing else. That’s a promise.
