3:47 am · the relay problem

You agreed to split the night. Your turn ran long — babies don't keep schedules. Now your partner's alarm — set in stone last night — is already out of sync with what the baby actually needs.

How BabyRelay fixes it

One alarm. Two phones. Always in sync.

The alarm doesn't live on a single phone — it lives in the relay. Move it, and both phones update together.

Step 01

You log the feed.

Three taps to save the amount and the time. Half-asleep, one-handed, from the rocking chair — and the next turn is queued automatically.

Step 02
S
S

You move the alarm.

Feed ran 40 minutes long? Slide your partner's alarm to a better time. Their phone updates the moment you do — no nudge, no text, no waking them to ask.

Step 03

Their turn starts.

The alarm fires on the right phone at the right time — the one you adjusted to, not the one you guessed at bedtime. No text to confirm it landed.

A closer look

Calm by default. Loud when it counts.

The home screen tells you when the next feed is due. The lock screen reminds you without nagging. The history is what your pediatrician asks for.

What's inside

Everything tracked. Nothing locked.

One price. Both parents. Every feature. The shared alarm is the differentiator — but the rest of the app holds up too.

Both parents

Full access for two.

No account sharing, no “primary parent” hierarchy. Each parent has their own login, their own color, and their own view of the relay.

History

Patterns at a glance.

Feeds and diapers visualized as a 24-hour spark. See when she's been cluster-feeding, when she's been quiet, and what the last shift looked like.

The whole care team

Caregivers welcome.

Add a nanny, a grandparent, or anyone else doing the work. Each one gets their own login and color in the relay. Twins or a second baby? Same one-time price.

Pricing

Pay once. Sleep better.

No subscription. No tiers. No “premium” features dangled in front of exhausted parents at 3am.

Questions

Things parents actually ask.

Yes — that's the entire point. On iOS we use Apple's Critical Alert entitlement, which bypasses Do Not Disturb and silent mode. On Android we use full-screen intent notifications on a high-importance channel with alarm-category audio. Both ring at full volume regardless of system settings.
No. One $7.99 unlock covers your whole family — partner, nanny, grandparents, anyone you invite. Apple Family Sharing is enabled, so your co-parent gets it free. They install the app and join with your family invite code.
Your feed log is yours. Data is encrypted in transit and stored on Convex (our backend). We don't sell, share, or train models on your baby's data. Ever.
Yes — twins, siblings, whatever the household looks like. Each baby has their own countdown, their own history, and their own alarm schedule.
Absolutely. Solo logging (feeds, diapers, history, the 24-hour chart) is free forever. The $7.99 unlock is for the two-parent / caregiver handoff. Solo parents who want a self-reminder alarm get that too.
In v1, sign-in is per-device. If you switch phones, your co-parent (if you have one) sends you the family invite code to rejoin — your shared baby history is on the cloud and intact. Cross-device sign-in via email magic link is on the roadmap.
