Know when the next nap is coming.
Cradler watches how long your baby has been awake and calculates a calm countdown, based on their age and the last five wake windows they've shown you.
The sleep app that doesn't shout.
Cradler turns your baby's rhythm into one calm answer: when the next nap is coming. Nothing more.
WHY CRADLER
Most baby apps hand you a dashboard. We hand you a moment.
When your baby is overtired, you don't need charts. You need to know if the next nap starts in thirty minutes or three hours. Cradler reads the patterns you're already making and tells you, calmly, what's coming — so you can stop refreshing and start rocking.
Three things, done well.
Eight sounds, no clutter.
Womb, rain, pink noise, lullaby, heartbeat, fan, shushing, and white noise. Each one carefully chosen, looping seamlessly, with a timer that fades out gently.
Two parents, one timeline.
When one of you starts a nap, the other sees it on their lock screen in real time. No syncing, no refreshing, no texting “is he sleeping?”
THE WAKE WINDOW
The one number that matters.
Sleep science has a name for it — the window between waking and needing to sleep again. Miss it by ten minutes and the next nap fights you. Cradler learns your baby's window and shows you, live, how much of it is left.
Based on the Weissbluth wake window framework, adjusted weekly as your baby grows.
“The countdown is the whole app. Everything else is there to make the countdown trustworthy.”
Sounds that earn their spot.
Not thirty. Not a hundred. Eight, picked because they actually work.
