For partners, grandparents & sitters

Both parents see every feed.
The moment it happens.

LunaLog is one shared log for your baby's day. Log a bottle on your phone and it is on your partner's phone before you've put the baby down — no texting, no "did you already…", no handoff interview.

Sharing is free. No card required. Your partner needs nothing but the link.

Grandma: wet diaper, 3:40 PM

The 3 AM shift shouldn't start with a quiz. When one of you has the baby and the other has the night off, the log is the handoff — the last feed, the last nap, the last diaper, on the phone in your hand.

Three steps. Ten seconds.

  1. 1

    Add your baby

    Name and birth date. LunaLog starts shaping the day from the first log.

  2. 2

    Share the invite

    A link or a QR code from the Caregivers page. Text it, AirDrop it, or hold up your phone.

  3. 3

    They tap, they're in

    Your partner signs in and sees the same live timeline — in a browser or the app, their choice.

The end of “did you feed her?”

Everyone caring for your baby shares one live timeline. Every entry shows who logged it and when, so a handoff is a glance, not a conversation — and the night shift knows exactly where the day left off.

  • ✓Real-time sync to every caregiver's phone
  • ✓Works in any browser — grandparents never install a thing
  • ✓Active timers travel too: start a nap, your partner sees it running

One plan, not two opinions

LunaLog predicts the next nap from the naps you've both logged and shows the same window to everyone. Whoever has the baby at 2 PM sees the same "wind-down at 2:40" — no negotiating from memory.

  • ✓Next-nap prediction and bedtime suggestion, shared
  • ✓One Premium subscription covers the whole household
  • ✓A weekly report you can both read on Sunday night

Sharing questions

Does my partner need to install anything?

No. Every caregiver can use LunaLog in a browser at app.lunalog.io, on iPhone, or on Android — whichever they already have. Grandparents and sitters usually just use the web link.

How do I add my partner?

Open your baby’s profile, tap Caregivers, and share the invite link or QR code. Your partner taps it, signs in, and sees the shared timeline immediately — about ten seconds end to end.

Is sharing free?

Yes. Logging feeds, naps and diapers with real-time sync to every caregiver is part of the free plan. Premium adds the intelligence layer — nap prediction, Today’s Plan and the weekly report — and one subscription covers everyone who shares the baby.

Does my partner have to pay for Premium too?

No. Premium is per household, not per person: if one caregiver subscribes, every caregiver on that baby gets it. There is no second subscription and no surprise paywall for the other parent.

What if we both log the same feed?

Every log shows who recorded it and when, so a double entry is obvious and takes one tap to delete. In practice the live timeline prevents it — you see the feed appear on your phone the moment your partner saves it.

Can I add a nanny or daycare and remove them later?

Yes. Invite as many caregivers as you like, and remove anyone from the Caregivers page at any time. Their access ends immediately; the records they logged stay with the baby.

Two phones.
One baby log.

Start free in your browser, invite your partner in ten seconds, and never ask "did you feed her?" again.
