Baby tracker

Made for short nights.

Elio keeps track of your baby’s days, and looks after you along the way. A feed, a nap, a diaper: a few seconds each, even at 3 a.m. with no signal.

Free to start. On iPhone and Android.

The day dial

The whole day, at a glance.

The dial is Elio’s home screen. Midnight sits at the top and noon at the bottom, and every feed, nap and diaper lands at its hour. One look tells you where the day stands.

  1. Sleep draws an arcFrom when they fell asleep to when they woke.
  2. Each feed is a dotBreast or bottle, with the amount or the minutes.
  3. Each diaper is a tickJust outside the ring, so it never hides a feed.
  4. Now is the lavender lineThe hours still to come stay empty.

Rest a finger on a mark and it tells you the rest: 120 ml at 9:50, a nap of 1h 20m.

Log

Four gestures, a few seconds.

At the bottom of the home screen, the four everyday gestures. Each opens with one tap and saves even offline.

Sleep

No timer to remember to stop.

At 3 a.m., nobody remembers to stop a timer, and the log ends up wrong. In Elio, sleep is two times: when it started and when it ended. The duration works itself out.

“Just fell asleep” sets the start to now. When your baby wakes, one tap on “Just woke up”.

Forgot a nap yesterday? Open that day from the calendar and add it where it belongs.

See the rhythm take shape.

This week against last, in plain words. The nights getting longer, the time between feeds, how your baby is growing. And each morning, one observation drawn from what you logged.

Four questions, one door each

  • Are the nights longer?
  • Is the feeding settling?
  • Is the growth steady?
  • How are the days going?

When something drifts from the usual, like fewer feeds or three short nights, a quiet word appears. Never more than two, and never a diagnosis.

Premium The finest charts, including growth on the WHO curves, are part of Premium.
AssistantPremium

An answer that knows your nights.

Ask your question, even at 3 a.m. The assistant answers from your baby’s own logs, names its sources, and points you to a professional when the situation calls for one.

Its references are your country’s health authorities, such as Santé publique France, the NHS or the American Academy of Pediatrics.

Three questions are free, to try it.

A guide, not a doctor. It makes no diagnosis.
For you

And you, how are you holding up?

Elio also looks after the ones keeping watch. Each evening, one word about you and a line if you like, with your hours of sleep and your mental load.

Your evenings become curves, and their night sits beside your mood the next morning.

Your lines stay yours. Nobody else reads them, not even the other parent, even once synced.

TogetherPremium

One thread for both parents.

One invite code, and the other parent, a grandparent or the nanny follows the same day from their own phone. No double entry, and every entry says who logged it.

Each person gets their own access

Read everythingLog daily careLog everything

For an afternoon at grandma’s, prepare the day: Elio proposes the one it knows from the last week, and you correct it.

No constant connection. Elio fetches what the other one logged each time it opens, so the battery stays calm.

Inviting is part of Premium. Joining a family with a code stays free, and your diary stays private.

At night

Dark and quiet, even at 3 a.m.

The night shield keeps every screen dim and calm, tuned for a room where everyone else is asleep, and readable one-handed.

Gentle reminders, silent, only the ones you turn on.

Touch and hold the app icon to log a feed or a nap without going through the home screen.

A light theme for the daytime, if you prefer.

WidgetsiPhone

See it all without opening Elio.

On iPhone, widgets for the Lock Screen and the Home Screen: the time since the last feed, and the day’s sleep and diapers. The one for the Lock Screen is made for the night.

Wherever you are

Five languages, six countries.

Elio speaks English, French, German, Spanish and Italian. The checkups, the vaccines and the emergency numbers follow your baby’s country, whatever language your phone speaks.

Questions

What parents ask us.

Is Elio free?

Yes. Logging feeds, sleep, diapers and growth, looking back at any day, following how you are doing and exporting a summary for the doctor are all free. Premium adds the assistant, family sharing, more than one child and the finest charts.

Does it work without a network?

Yes. Everything is saved on the phone first, even in airplane mode. As soon as the network is back, your account backs up what you logged.

Does Elio replace the pediatrician?

No. Elio is a tracking tool, not a medical device, and the assistant makes no diagnosis. If something about your baby worries you, call a professional. For a fever before 3 months, labored breathing or a very floppy baby, call your emergency number.

Can both parents follow the same day?

Yes, with an invite code. Each of you logs from your own phone, and everything lands in the same thread. Inviting is part of Premium, joining a family stays free.

Where is my data stored?

On your phone, encrypted, and on your account, in Ireland, inside the European Union. Nothing is sold and nothing feeds advertising. The details are in the privacy policy.

Which phones does it run on?

iPhone and Android. The widgets are on iPhone only.

How do I stop Premium?

From your store’s settings, App Store or Google Play, whenever you like. Your logs stay yours, with or without Premium.
