How to share a baby tracker with your partner
How do I share a baby tracker app with my partner?
Invite them as their own account rather than handing over one login. In BubSync, open the family screen and send an invite; they join with their own sign-in on their own phone. Both then write to one timeline, so a feed logged at 3 am is on the other phone by morning. Live sharing is a Premium feature.
Own login, not a shared one
Two people on one account cannot tell who logged what, and every entry looks like it came from the same person. Separate accounts fix both.
Who sees what
An invite asks what the person is (a parent, family, or a carer) and they see what that role should see, for the babies you chose.
What each plan does
Logging and the 24-hour handover link are free on every plan. Live sharing between two accounts is what Premium adds.
Why not just share one login?
It is the fastest thing to do and it is the thing most couples try first, so it is worth saying exactly what goes wrong. With one account on two phones, no entry can say who made it. The single most common question in a house with two carers, "did you already feed her, or was that me?", becomes unanswerable by the app that was supposed to answer it.
The practical problems follow from there. A shared password is a password neither person can change without locking the other out. Notifications go to whoever is signed in rather than to the person who needs them. And when the relationship or the arrangement changes, there is no way to remove one person’s access without resetting the account for both.
Separate accounts in the same family cost nothing extra to set up and remove all of that. Each person signs in as themselves, each entry carries their name, and access can be changed for one person without touching the other.
What can each person see once it is shared?
What somebody sees depends on what you said they were when you invited them. A partner invited as a parent sees everything for every baby, which is almost always what you want between two parents. A grandparent or a babysitter invited as a carer sees only the babies you shared with them, and a scoped view of the day rather than your whole family’s history.
This is the part most trackers in the category do not do. The common model is "share the account", which is all-or-nothing: the sitter who has your logins for one Saturday evening has them for everything, forever. Being able to give a sitter one baby rather than your whole family is a different shape of answer, and it is the reason the invite asks who someone is rather than which switches to turn on.
You can change what a whole group sees later and it applies to what you already shared, and any single entry can carry its own answer to who can see it.
Does sharing a baby tracker with your partner cost anything?
Logging is free, on every plan and offline. So is the handover link: you can send a snapshot of the day as a link that opens in any browser for 24 hours, and the person you send it to needs no account and no app. For a one-off, like a babysitter on Saturday or a grandparent for an afternoon, that link is often the whole answer, and it costs nothing.
What Premium adds is live shared care: a partner, grandparent or carer inside the family with their own login, so the handover keeps updating instead of freezing at the moment you sent it. Two parents logging into one timeline day after day is that case. On the free plan an entry stays on the phone that logged it, so the second phone is not a second view of the same day.
- Free on every plan: logging all activity types, offline, and the 24-hour handover link
- Free: writing your care essentials and instruction manual for whoever is taking over
- Premium: a login of their own for each carer, and entries syncing between phones
- Premium: delivery receipts, so you can see the 3 am feed reached the other phone
What about grandparents, a nanny or daycare?
The same invite handles all three, with a different answer to the "who is this person" question. A grandparent who has the baby every Thursday is usually family; a nanny or a regular babysitter is a carer, scoped to the babies they actually look after. Daycare is more often a handover-link case than an account case, because the relationship is with a centre rather than a person.
The thing worth getting right early is that a carer does not need to see everything to be useful. A sitter who can log a feed and read today’s essentials is fully equipped for the evening without having access to eighteen months of your family’s history.
How to set up a shared baby tracker with your partner
Five steps, done once. At the end both of you are logging into the same timeline from your own phone, and each entry says who made it.
Set your own account up first
Whoever installs first creates the family and adds the baby. This account becomes the primary parent, which is the one that can invite and remove people later. It is worth this being the person more likely to handle the admin, though it can be either of you.
Open the family screen and start an invite
The family screen lists everyone who currently has access to your babies, which at this point is just you. Starting an invite from here is what creates the second seat, rather than your partner installing the app and signing up separately. Two separate sign-ups create two unrelated families that will never see each other’s entries.
Choose what they are, not what they can tap
The invite asks who the person is: a parent, family, a carer, or a mix you pick yourself. Choosing "parent" for your partner gives them full read and write access to every baby. You are describing a relationship rather than configuring permissions, and the access follows from it.
Send the invite link however you already talk
The invite goes out as a link you send by message or email. Opening it on their phone takes them to sign-in or sign-up and then straight into your family. If they already have the app installed from a previous attempt, the link still joins them to your family rather than making a second one.
Check it from both phones before you rely on it
Log one feed on your phone and confirm it appears on theirs. This is worth doing while you are both awake rather than discovering at 3 am that one of you never finished sign-up. Each entry should show who logged it; if it does not, the second account has not joined the family.
Frequently asked questions
- Can two parents use the same baby tracker app?
- Yes, and the right way is two accounts in one family rather than one login on two phones. Each parent signs in as themselves, both write to the same timeline, and every entry records who made it, which is what makes "did you already feed her?" answerable. In BubSync, live sharing between accounts is a Premium feature; logging itself is free.
- How do I share a baby tracker app with my partner for free?
- The free option is the 24-hour handover link: it sends a snapshot of the day that opens in any browser, with no account and no app needed at the other end. It does not keep updating after you send it, so it suits a one-off handover rather than two parents sharing a baby day to day. Continuous live sharing between two accounts is Premium.
- Is there a baby tracker that syncs between two phones?
- BubSync does this with Premium live sharing: both phones sign in as separate accounts in the same family and write to one timeline, with sent, delivered and seen status for every device so you can tell the 3 am feed actually arrived. Entries are written to the phone first and sync afterwards, so logging still works with no signal.
- What happens if my partner logs a feed while I am offline?
- Their entry is written on their phone immediately and queued. Yours does the same in the other direction. When a connection returns, the queued entries sync and both timelines reconcile. Nothing waits on signal to be recorded, only to be shared. On the free plan an entry stays on the phone that logged it, because syncing between accounts is what Premium adds.
- Can I stop sharing with someone later?
- Yes. The primary parent can remove someone’s access from the family screen without affecting anyone else in the family, which is the practical advantage of separate accounts over a shared login: removing one person does not mean resetting the password for everybody.
- Do we both need the same kind of phone?
- No. BubSync is released on Google Play for Android, runs in any browser, and is available on iPhone as a public Apple TestFlight beta while the App Store submission is in review, so one of you on Android and the other in a browser is a normal setup. The browser version is often how a grandparent or carer joins without installing anything.
