Bundle of Joy Start free

Shared between both parents

One baby tracker. Both parents. The same answer.

Bundle of Joy is a baby tracker for both parents. Invite your partner with a link, and every time either of you opens the app you see the same feeds, diapers and medicine, with who logged each one. Free for two of you, on Android or in any browser.

Free for two, no card · Set up in a minute · No ads, no AI, no feed to scroll

The Today screen of Bundle of Joy, a baby tracker for both parents: last feed 45 minutes ago, formula 120 ml, with today’s totals underneath; last diaper 1 hour 19 minutes ago, wet and dirty; last medicine 3 hours ago; and an Invite your partner button.

Why it exists

No more texting “did you feed her?”

It is 3AM. Your partner did the last bottle and is finally asleep. The baby is awake again, and the only record of that bottle is in the head of the one person you do not want to wake.

So the bottle goes in the app instead. That is what a baby tracker for both parents is for: whoever does the feed logs it, in three seconds, one-handed. The other one sees the time, the amount, and the name of who did it. Two phones, one record, nothing to ask.

Set up

Invite your partner with a link.

Two accounts, one family. Nobody shares a password.

  1. Sign up.

    Email and password, or your Google account. Add your baby’s name and birth date. About 30 seconds.

  2. Send the link.

    Tap Invite your partner on the Today screen. It goes out through your phone’s share sheet, in whatever chat you already use.

  3. They open it.

    They see who is inviting them, create their own account and join your family.

Each link works once and expires after 7 days. If it expires, send a fresh one.

Same record, both phones

Logged on one phone. There on the other.

A feed logged on your phone is in the app when your partner opens it, and the other way round. The Timeline lists everything newest first, with the name of whoever logged it next to the time, so a handover is a glance, not an interview.

  • Every event shows who logged it. Feeds, diapers, medicine, measurements, all of them.
  • You edit or delete your own entries. Whoever owns the family can fix any of them.
  • Filter and search. Filter by type, or search notes, medicines and foods.
  • It is not a live feed. The app refreshes when you open it, when you come back to it, and when you pull down.
One of you has no signal? Log anyway. It is saved on the phone and sent when a connection returns, and your partner sees it when it lands. How offline works
The Timeline screen: a search box, filter pills for All, Feeds, Diapers and Medication, a Today header reading 4 feeds, 3 diapers, 1 dose, then the day’s events newest first: a 120 ml formula feed 45 minutes ago, a wet and dirty diaper, a sleep, a Vitamin D dose, another feed and tummy time. This demo family has one member, so rows show only the time; with two members each row also shows who logged it.
One-person demo family. With two of you, each row reads “45m ago · Ana”.

Free for two people. One link, and you both see the same record.

Any two phones

A baby tracker for both parents, whatever phones you have.

One of you on Android, the other on an iPhone? It is the same account and the same family either way.

  • Android. Install the app from Google Play, or open app.bundleofjoy.love in Chrome and choose Add to Home screen from the menu.
  • iPhone. Open app.bundleofjoy.love in Safari, tap Share, then Add to Home Screen. It opens full-screen, like an app: on iPhone, that is the version of Bundle of Joy you run.
  • Anything with a browser. A laptop, a tablet, a grandparent’s phone. Same sign-in, same record.

Free for both of you

Free for two. Premium for the rest.

Both of you log feeds (formula in ml or oz, breast left, right or both, solids with the food name), diapers, and medicine with dose and unit. Weight, height and head circumference go on the WHO growth charts. Backdate anything in two taps and add a note to any of it. Built for 3AM

  • Two people in the family. Premium removes the limit, so grandparents and a nanny can join too, each with their own account and their own name on what they log.Premium
  • One baby. A second baby is Premium; each keeps their own timeline and charts.Premium
  • The last 7 days in the app. Older entries are kept, not deleted. They come back the moment you upgrade, and they are in your CSV export either way.
  • Sleep, bath, tummy time and temperature, and a photo on any event.Premium

Premium is per family, not per person. One subscription covers everyone in it, so your partner never pays twice.

Private

Only the people you invite see any of it.

Sharing between two phones means the record lives on a server, so what happens there matters. Every family’s data is isolated at the database level, not by a filter in the app. No ads, no data selling, no AI, no social feed. Usage analytics run under a pseudonymous ID and never include your baby’s name, notes, photos or measurements.

Questions

Sharing, answered.

Do we both need an account?

Yes, one each. You invite your partner with a link and nobody shares a password. Every event then shows who logged it.

How sharing works

How do I share it with my partner?

Send the invite link from the app. They open it, create their account and join your family. From then on you both see the same record every time you open the app, and every event shows who logged it.

Shared baby tracker

Can I add a grandparent or a nanny?

Yes, with Premium: grandparents, a nanny, anyone you invite. The free plan has room for 2 people in the family, and Premium removes the limit.

See what Premium adds

Does it work on iPhone?

Yes. On an iPhone you open app.bundleofjoy.love in Safari and add it to your Home Screen; it then opens full-screen and does everything the Android app does except the widget. There is no App Store app, and Android has one on Google Play. Same account, same data either way.

Using it in a browser

Does it work without signal?

Yes. Log as normal; with no signal the event is saved on your phone and sent when a connection returns, and your partner sees it the next time they open the app. You need to be online the first time you sign in.

Offline baby tracker

Do both parents pay?

No. Premium is per family, not per person. One subscription covers everyone in it.
