79%
of daily tracking tasks land on one parent
A University of Bath study of 3,000 US parents found mothers manage 71% of the household mental load — and 79% of daily-grind tasks like tracking feeds and schedules.
Most baby apps are built for one phone, with your partner bolted on afterward — a “share code” here, a paywalled sync there, a log that’s stale by the time you open it. mybabynotes starts from the household instead: one log, live on every phone, a name and a time on every entry. When she logs the 2am bottle, it’s on your phone before you’re awake enough to ask.

Why one-phone tracking fails
The research on new parents keeps finding the same shape: whoever holds the tracker ends up holding the tracking — and the remembering, and the planning. A log both of you can see and write to attacks that at the root.

Pew finds the two parents honestly describe the same week differently. When only one phone has the record, there’s no shared picture to agree on.

In much of the category, “partner sync” is the premium feature. Here it’s the point of the app — realtime household sync is free in every version, forever.

What “shared” means here
Anything anyone logs appears on every phone instantly — feeds, diapers, sleep, meds. Live nursing and sleep timers run across all phones at once, so “is she still down?” is a glance, not a text.
Every entry carries who and when. The night work each of you does is simply visible — no recaps, no “by the way, I was up twice.” And deliberately no per-person scoreboards. Why visibility matters →
“Can you take her?” is a button. The app drafts a plan from her actual rhythm; you either start their cover on the spot or wait for a yes, and whoever’s covering is explicit — with a summary when it ends.How couples run night shifts →
iPhone parent, Android parent, laptop grandparent — it’s an installable web app, so nobody’s locked out by their phone. No app store, no family-sharing gymnastics; an invite code and you’re in.
Yes, always. Realtime sync across the whole household — both parents plus up to four more caregivers — is the core of the app, not an upsell. It’s free self-hosted (the code is AGPL open source), and hosted plans are priced per household, never per person: $5/mo, $50/yr, or a one-time $60 pass that covers 18 months without auto-renewing.
Yes. It’s an installable web app, so one parent on iPhone and one on Android see the same log — plus it works on a laptop. Open it in the browser, add it to the home screen, and it behaves like a native app: full screen, offline, push notifications.
The entry saves instantly on that phone and syncs to everyone else the second there’s signal. Neither of you ever waits on a spinner to log a feed, and nobody’s 3am bottle goes missing.
Realtime household sync, free in every version — on our server or yours.
