Why families choose Lalu

  • Works without a network

    Every entry is saved on the phone first, so the app works the same at 3 a.m. in airplane mode.

  • Everyone sees the same diary

    Entries reach the other caregivers' phones as soon as there is a network, each with the name of who saved it.

  • An entry never disappears

    If something cannot be sent, it waits on the phone until you deal with it. Nothing is dropped quietly.

Everything a day with a baby needs

Big buttons, a dark night mode and timers you can start with one hand.

  • Feeding

    Breast with a timer for each side and a pause, bottle with the amount, solids with the baby's reaction.

  • Sleep

    Naps and nights with a running timer, and a day sheet with the gaps between them.

  • Diapers

    Wet and dirty as two quick marks, with the details only when you want them.

  • Pumping

    The amount from each side, for each person who pumps.

  • Medication

    Doses as you give them, schedules and reminders, and the last dose shown before you log the next one.

  • Temperature

    Readings with the time and the method, and a fixed card about temperature in children from paediatric sources.

  • Your own events

    Tummy time, a bath, a walk — make the types your family needs.

  • Photos and voice notes

    On any entry. Location data is removed on the phone, before anything is saved.

  • Statistics

    Averages and the day's rhythm over 7 days, 30 with Premium — plain arithmetic, with what is counted shown on screen.

  • CSV export

    The whole history in a spreadsheet, free, whenever you want it.

Made for the whole family

Invite a partner, a nanny or the grandparents with a code, a QR code or a link. Everyone sees every entry of every child and who saved it, also the ones from before they joined.

Questions

Do I need an account?

No. You can start logging right away and the diary stays on your phone. An account is needed when you want to share the diary — your entries move to it.

Does it work without internet?

Yes. Every entry is saved on the phone first and is sent when there is a network again.

Is there an app for Android and iPhone?

Lalu runs in the browser on any phone, tablet or computer. Add it to the home screen and it opens like any other app. Apps in the stores are planned.

Does Lalu give medical advice?

No. Lalu is not a medical device: it does not make diagnoses, calculate doses or interpret your entries. If you are worried about your child, contact a doctor.

Is Lalu a baby monitor?

No. Lalu is a care diary: it keeps what you and the other caregivers write down. It does not listen to or watch your baby.

What happens to our diary if we stop paying?

Nothing is deleted. The owner keeps adding entries, and everyone in the family can still read and export the whole history for free.

Can I take my data with me?

Yes. The CSV export of the whole history is free in every plan, and deleting your account sends you a copy first.

Which languages does Lalu speak?

English and Polish, with metric or imperial units.

Good to know

The app is for recording information about caring for a child. It is not a medical device, does not make diagnoses and does not replace contact with a doctor, a midwife or a nurse.

Lalu is a diary, not an audio or video baby monitor.
