Baby tracker & AI sleep coach

Find your baby's rhythm. Find yourself again.

Cradle learns your baby's actual pattern, predicts the next sleep window, and builds a daily plan around how you parent — wake windows, demand-led, or a blend of both. Then it nudges you at the right moment.

Why Cradle

Most baby apps log. Cradle coaches.

Logging is table stakes. The hard part is knowing what to do with it at 4pm on a day that's gone sideways — and doing it in a way that fits the parent you already are.

You pick the philosophy

Wake windows, demand-led, or hybrid. Predictions, insights and copy all adapt to your choice — no app quietly telling you you're doing it wrong.

A plan that nudges you

Cradle builds tomorrow's schedule from today's real data, then taps you on the shoulder ten minutes before the sweet spot — not an hour after you missed it.

It takes care of you, too

A daily check-in on your mood and sleep, private from everyone else in the household. The only baby app that treats the parent as a person, not a data source.

The method

Wake windows are the whole thing.

A baby doesn't fall asleep because they're tired enough. They fall asleep inside a window — awake long enough to build sleep pressure, but not so long that they tip past it. Miss the window and the next hour is harder, not easier.

The ladder Cradle predicts from

Windows widen as your baby grows. These are the age bands the app actually uses — not a marketing simplification.

These are the bands the app schedules from, grounded in published pediatric sleep research and checked against what families actually log in Cradle. Cradle's full research basis is listed here, and it's the same page inside the app.

Not every window is the same length

The first window of the day is the shortest; the stretch before bed is the longest — often close to three times it. Cradle ramps them across the day instead of repeating one number, and softens the ramp as a baby drops naps.

What Cradle is doing all day

  • Reads your baby's actual logged pattern, not just their age.
  • Puts the next window on your lock screen before it closes, not after.
  • Lets you override the ladder if your baby runs long or short.
  • Or ignores the ladder entirely if you told us you feed and sleep on demand.
Why this app exists
“We built Cradle because wake windows were the thing that finally worked in our own homes — and because nothing out there was doing the timing for us. So we built the app we wanted at 3am.”
The team behind Cradle · Creator Lane Studios
Every baby is different. Cradle gives you the method and the timing; what your baby does with it is your baby's call. Nothing here is a clinical result or a promise about your baby.
New · Cradle on the web

Your baby's whole story, on a real screen.

Sign in with Apple or Google — or a connect code from the app — and every log you've ever made opens up on desktop: bigger charts, longer ranges, and a view you can actually turn toward a pediatrician.

  • Every report from the app, rebuilt for a wide screen — rhythm score, night consolidation, nap rhythm, feeding and diaper trends.
  • Ranges the phone can't hold — 90 days, six months, since birth, side by side.
  • Same numbers as the app. One engine, one source of truth — the web never disagrees with your phone.
  • Print or export for appointments — a clean summary instead of scrolling a phone at the pediatrician's desk.

Same account as the app. Nothing new to set up.

How are you feeling today?

Just for you — caregivers don't see this.

The part nobody else builds

Cradle takes care of you, too.

Every other app in this category treats the parent as an input device. Cradle asks how you slept and how you feel, keeps it private from the rest of the household, and watches for the stretch where it's been rough for days in a row.

It's the smallest feature in the app and the one parents write in about.

Questions

The things parents ask first.

Do I need to log everything for this to work?

No. Sleep is the signal that drives the schedule. If you log naps and nights, Cradle can predict wake windows and build a plan. Feeds and diapers make the insights richer, but they're not required.

What if I don't follow a wake-window method?

Then pick demand-led or hybrid during setup. Cradle changes what it predicts and how it talks to you based on that answer — it won't push a schedule you didn't ask for.

Can my partner or our nanny use it too?

Yes. Invite them to your household and logs sync live across everyone's phones. Your daily check-in stays private to you.

How do I sign in on the web?

Continue with Apple or Google, the same way you signed in on your phone. If you've never attached an account, open Cradle on your phone and grab a connect code from Settings — the web will ask for it. Your reports read the same data either way.

Is my baby's data private?

Your logs belong to you and your household, and nobody else. We don't sell data. See the privacy policy for the specifics.

It takes about four minutes to set up, and the first prediction lands the same day.
