A baby tracker for both parents: one log, two iPhones

What you need before inviting your partner

• Two iPhones with iOS 17 or later. Install Pipkin on both. There is no Android app.
• Each person signed into their own iCloud. Pipkin uses Apple's sharing system. A separate Pipkin account is not required.
• An internet connection for the invitation and syncing. If iCloud is unavailable or storage is full, resolve that before trying to set up sharing.

Sharing and everyday tracking are covered by the free-forever pledge. Optional Plus adds predictions and analysis; you can set up a shared log without subscribing.

How to share Pipkin between two iPhones

1. Start with the phone that already has your baby's log. Open Settings → Co-parent sharing, then Invite your partner. If you already share, use Manage co-parents.
2. Add your partner through the iOS sharing sheet. Follow Apple's prompts to choose the person and send the invitation. This is the step that grants access; sending a QR code or copying a link alone does not add a new participant.
3. Accept on your partner's iPhone. Open the invitation with Pipkin installed and follow the acceptance prompts. The QR code or link can help them open an invitation after they have been added.
4. Check the shared child and recent entries on both phones. Allow time for iCloud to catch up. Before the next handover, confirm that a recent entry is visible on the other phone.

Each caregiver keeps their own Apple Account and password. The shared household gives both people access to the same log; you do not need to create a second, independent record of the same baby.

What if an entry has not reached the other phone?

Syncing is not guaranteed to be instant. An entry saved offline cannot reach another phone until the device reconnects and iCloud processes the change.

• Check that both phones are online and signed into iCloud.
• Check that the invitation was accepted and both people have opened the shared child.
• Read any sharing or iCloud error shown in the app, including storage warnings.
• If the log still differs, contact Pipkin support with the app versions and the error message. Avoid deleting the app or the shared household as a troubleshooting shortcut.

Who can see the shared log?

The caregivers you invite can read and add to the shared household. Child logs are stored on devices and synced through iCloud, including Apple's shared storage when you turn on sharing. Pipkin does not receive those logs.

The owner controls who is invited. Removing a caregiver stops future syncing to them, but copies they already received may remain on their device or in their iCloud. The privacy policy explains this, along with the separate anonymous usage signals and subscription reporting.

Quick answers

Can two parents use the same baby tracking app?

Yes. In Pipkin, one parent invites the other to a shared household. Both can read and add entries on their own iPhones. Each needs iCloud; there is no separate Pipkin account. Changes sync through iCloud, so the other phone may take time to catch up.

Do both parents have to pay for the baby tracker?

No. Tracking and caregiver sharing are free in Pipkin. Optional Pipkin Plus adds analysis and predictions, and one subscription covers both parents. You do not need to start a trial to share a log.

Can grandparents or a nanny use the shared log too?

Yes, if they use an iPhone and iCloud. The household owner can add them through the sharing controls. Removing someone stops future syncing; it cannot erase copies they already received.

Can we share between an iPhone and an Android phone?

No. Pipkin is available for iPhone with iOS 17 or later. If either caregiver uses Android, choose a tracker that supports both platforms.

Do we need to share an Apple Account?

No. Each caregiver uses their own Apple Account for iCloud. Invite the other person to the household rather than signing both phones into the same account or sharing a password.
