Baby Tracker Apps to Share With Your Partner: Free for Both Parents? (2026)

Our pick for a baby tracker app for both parents, one you can share with your partner for free, is Robin Baby. We make Robin Baby. Up to 3 people (you plus two) share one timeline for free, each with their own login, on iPhone and Android. A nursing or sleep timer started on one phone keeps running on the other, the other parent gets a notification when you log, and entries added by someone else show their name. ParentLove is the pick if a sitter should only view, not edit. Huckleberry and Baby Tracker by Nighp are free to share too, but everyone signs in with the same email and password.

We checked the apps using official websites, help pages and US App Store listings on October 18, 2026, plus the App Store reviews collected in our research. Sources are linked under each app. Where we couldn’t confirm something, we say so.

Best shared baby tracker apps by family

• Best for both parents: Robin Baby
• Best for a sitter who should only view: ParentLove
• Best if you’re already using it: Huckleberry (one shared login)
• Best long-standing free app (with ads): Baby Tracker by Nighp
• Best if you’d rather pay once for a big circle: Nara Baby
• Best for daycare and a computer: Baby Connect
• Best for no accounts at all, two phones: Pebbi
• Sharing is paid: Baby Daybook, Glow Baby

What actually matters when two people log

For a shared baby tracker app, check these four things before you pick:

1. Can the second person log without paying? Several popular apps now charge for this.
2. Own login or one shared password? Separate logins can make sharing easier to manage. Check whether you can control notifications and remove a caregiver later.
3. Does a running timer show on the other phone? At 3 a.m. the useful question is “is she still feeding, and which side?”, not what was logged an hour ago.
4. Does it work across iPhone and Android? Apps that sync through iCloud only work between Apple devices.

Comparison: baby tracker apps for both parents, free vs paid

Checked October 18, 2026 using official pages, US App Store listings and reviews. “Not documented” means we couldn’t confirm it in those sources, not that the app can’t do it. Prices and plans change, so check the listing before you decide.

1. Robin Baby: best for both parents

Free: sharing with up to 3 people in total (you plus two), live sync, shared timers, notifications when someone logs, and names on entries added by someone else, plus shared reminders, notes and up to 3 children. Premium: $9.99 a month or $59.99 a year in the US, with 7 days free and no card needed. It adds unlimited people and more than 3 children, and covers the whole family if anyone in it pays.

How sharing works in Robin Baby:

• Invite: open Profile → SHARING → Invite Partner, and tap Send Invite. Your partner gets a link and a 6-character code. They install Robin Baby on iPhone or Android, sign in with their own account, and tap the link or enter the code. The link works for 7 days.
• Live sync: a new entry shows up on the other phone within seconds while the app is open, and the app catches up as soon as it’s opened.
• Shared timers: start a nursing timer on your phone and it runs on your partner’s too, including side switches. Sleep, crying and custom timers work the same way, and either of you can stop them. On iPhone, the running timer can also show on the other parent’s Lock Screen if enabled; on Android it shows as an ongoing notification.
• Notifications: the other parent gets a push when someone logs an entry or starts a nursing, sleep or crying timer, in their own app language. Each person can switch these off in Notification Preferences → Event Notifications.
• Grandparents and nannies: invite them the same way. Only the owner can remove someone, anyone can leave with Leave Family, and the entries they logged stay with the family.

Where Robin Baby is weaker: there’s no view-only role yet, so everyone you invite can add, edit and delete entries. A pumping timer stays on the phone that started it; the finished session syncs. There’s no web app for a daycare computer. And an account that already has its own baby log can’t join a second family.

2. ParentLove: best for a sitter who should only view

Free: unlimited caregivers, each with their own login, and multiple children. Paid: an optional one-time Pro ($24.99) or Pro Family ($39.99).

Of the nine apps compared here, ParentLove is the only one that documents view or edit access per person, set per child and per feature, so a babysitter can check the last feed without changing anything. It also lists “syncable timers” for feeding and sleep and real-time sync on iPhone and Android. We found no sync complaints in the App Store reviews collected for this research.

The catch: the App Store listing is in English only, and the Android app shows ads.

3. Huckleberry: free, but one shared login

Free: logging and “Sync with multiple caregivers across devices”. Plus and Premium add SweetSpot, Lock Screen timers and the Berry AI chat. They don’t change sharing.

How to share Huckleberry with your partner

Huckleberry has no invite or partner account. Its help center says the way to share is to sign in with your account on your partner’s phone, so you both use the same email and password. If you signed up with Apple or Facebook, add an email login in the app first. One parent can start a sleep session and the other can stop it.

What a shared login means in practice: everyone has the same access, reminders sync to every signed-in device, and we couldn’t confirm a way to remove just one caregiver. Huckleberry also notes that sync needs both phones online, and that low power mode or Background App Refresh being off can stop it. One review reports “takes days to sync” (English, UK App Store, October 17, 2025).

4. Baby Tracker – Newborn Log (Nighp): free sync, with ads

Free: everyday tracking and syncing between phones, with ads. Plus: $5.99 a month or $49.99 a year for no ads and “What’s Next” cues, and one Plus now covers everyone in the sync group.

Sharing works through a sync group: on the phone with the data, go to Settings, then Sync Data between Devices, and create a group with an email and password. Everyone else joins with the same email and password. Nighp says it has tested up to 4 devices in one group.

The catch: there are no separate logins or documented roles. Sync complaints appear in 2026 reviews, including “the syncing seems buggy” (English, US App Store, January 2, 2026). The FAQ is old, so its menu labels may differ from the current app.

5. Nara Baby: unlimited caregivers, but no longer free

No free plan: after a 7-day trial you can view and export but not add entries. Paid: $9.99 a month or $99.99 lifetime, which covers unlimited caregivers and children on one payment.

Each caregiver gets an email invite from the Family tab and makes their own account, and everyone has full access. The family creator can remove a caregiver. If you’re happy to pay once and have a big circle of helpers, the lifetime plan is good value. A September 16, 2026 US App Store review in English reports timers going wrong when one parent starts them and the other stops them. Nara isn’t on the App Store in Mexico or Brazil.

6. Baby Connect: best for daycare and a computer

Free: a 7-day trial, then read-only. Paid: Family plan $49.99 a year (also 6-month and other plans), and one subscription covers every parent and caregiver.

Baby Connect has a documented web app, which helps when a daycare or nanny logs from a computer. You invite people by email or with an invitation code, there’s no limit on caregivers, and you can leave notes and messages for each other. With automatic settings, the app syncs when it starts, when you add an entry and every 5 minutes. Some recent reviews report sync issues.

7. Pebbi: two phones, no accounts

Free: 2 caregivers and 1 baby, with real-time sync. Household: $19.99 a year for up to 10 caregivers and 5 babies.

One parent shows a QR code and the other scans it (an invitation code also works), with no email or password. It’s a good fit for a couple who want to connect without creating accounts and only need to track one baby. It’s a small app so far, with 34 ratings on the US App Store.

8. Baby Daybook: sharing is Premium

Free: logging (Google Play lists ads); reviews say history beyond 14 days is paid. Premium: the US App Store lists $59.99 a year and $99.99 lifetime, but has conflicting price rows, so we couldn’t confirm the standard price. Reviews place the move to paid family sync around mid-2025.

Each caregiver signs in with their own account and you add them to the baby’s caregiver list. One Premium covers every connected caregiver, and it has Android and Wear OS apps. An October 14, 2025 UK App Store review in English describes a stopped sleep timer still showing as running on the partner’s phone.

9. Glow Baby: only the Family Plan shares

Free: solo tracking. Paid: Glow’s help center says a second caregiver needs the Premium Family Plan ($89.99 a year on its support page); regular Premium doesn’t add caregivers. You invite by email, per baby. Glow’s own help article on sync problems calls signing out and back in “not a permanent solution”. The iPhone app hasn’t been updated since November 2025.

Also worth knowing: nappi shares free with a household code, timers included. PiyoLog shares free with a code, no email, and has a separate PiyoSup app with view-only access for sitters. My Baby by Aleksei Neiman is free but syncs through iCloud, so it only works if both of you have an iPhone. Nanit’s logs need a Nanit camera and allow 2 users for free. For Baby Tracker by Amila, we couldn’t confirm real-time partner sync; reviewers describe exporting and emailing data instead.

How to choose a baby tracker to share

• Two parents, different phones: pick an app with its own login per person and iPhone + Android support. Robin Baby and ParentLove are free; Nara Baby is paid.
• You’re breastfeeding and your partner does bottles or nights: check that a running nursing timer and the last side show on the other phone. Robin Baby shares both.
• A nanny or grandparent helps: decide whether they should edit. ParentLove has view-only access; in Robin Baby everyone can log.
• Daycare on a computer: Baby Connect has a web app.
• You’re already in Huckleberry: sharing is free, but it’s one login for everyone. If you want separate logins, compare the options above before switching.
• Before you pay: check that one plan covers your partner. In the paid apps here, the plan that unlocks sharing covers the whole family, according to each app’s own pages; at Glow that’s only the Family Plan.
