A calm baby tracker for everyone caring for your little one

Log feeds, sleep and diapers in a tap. Share one timeline with your partner, grandparents and anyone who helps. It even works with no signal.

Also on Google Play for Android. iPhone: coming soon.

The demo needs no sign-up: sample data, kept in your browser.

No ads. No tracking. Your data stays yours.

Orion's timeline for today: a nap with its timer still running, then the day's feeds, pumping and diapers.
Orion's Trends screen: a stacked bar chart of diapers per day, with the weekly average of 5.8.

What Orion does

Everything for the first year, nothing in your way

Built for tired hands at 3am: big buttons, one-handed use, and a dark look that doesn't wake the room.

  • Log in a tap or two

    Feeds, bottles, pumping, sleep, diapers and baths. Add solids, medicine, temperature and growth, or make your own.

  • Everyone on the same page

    Invite a partner or caregiver. Everyone sees the same timeline and who logged what, and nobody asks "when was the last feed?"

  • Works offline

    Everything saves on your phone first and syncs when you're back online. Hospital, plane or dead zone, it just works.

  • Trends and a doctor report

    See patterns in feeds, sleep and diapers, get a hint of the next nap, and share a one-page summary at the check-up.

  • Gentle reminders

    Quiet nudges when a feed or change is due, plus a check that a medicine dose is safe before you give it.

  • Milk stash, labels and tags

    Label every bag with a QR code, use the oldest milk first, and tap an NFC sticker by the changing table to log.

On the web too

The whole timeline on a bigger screen

Open Orion in a browser on a laptop or tablet: your timeline on the left, the log you picked on the right, search with Ctrl+K and keyboard shortcuts. Sign in with the same account as the app.

The Orion web app in a wide browser window: a sidebar with search and the Log button, today's timeline, and the details of a breastfeed beside it.

Orion's Children and people settings: two children, Ava and Theo, and who can see each of them.

Fast by design

One tap to start. One tap to stop.

Start a timer, or fill in something that already happened. Orion remembers what you logged last and keeps the next step small.

  • Quick log from your home screen or lock screen
  • Twins or more than one child, in one place
  • Big targets and a dark, night-friendly look
Orion's reminders: feed every 3 hours, a diaper check, a nap reminder and a bath reminder that is switched off.

Calm, not noisy

Reminders that help, not nag

Choose what you want to be reminded about and how long after the last one. Notifications are quiet by default, and whoever is off duty tonight can sleep.

  • Feeds, pumps, diaper changes, naps and baths
  • Say who is on night duty; the other phone stays quiet
  • Your choice, always: turn any of it off

Private by default

Your baby's data is yours

Orion holds children's health information, so we treat privacy as part of the product.

  • No ads, no tracking

    No advertising, no analytics and no tracking tools. Crash reports are opt-in and never include your baby's details.

  • Take it with you

    Export everything from the app at any time, as one file or as a spreadsheet of your logs.

  • Delete it any time

    Deleting your account removes your data from our servers and your phone. How deletion works.
