Rattle Worlds with Child Lock
Sensory play for babies
Free · In‑App Purchases
Tap, shake and explore! Sensory play with familiar nursery rhymes to keep your little one busy.
Soothe a fussy little one — anywhere, even in airplane mode.
Rattle Worlds is a gentle sensory rattle for the touchscreen age, built for one very real parenting moment: your baby is upset, your hands are full, and you need calm right now. Hand over the phone and a soft, glowing world lights up under their fingers, quietly drawing their attention away from the tears and into wonder.
CALM AND DISTRACT, ON DEMAND
Fussing in the car seat. Melting down on a plane. Squirming through a diaper change, a restaurant dinner, or a long wait at the doctor's. Rattle Worlds is made for exactly these moments — a warm, mesmerizing world your baby can touch and change, with slow motion and soft light designed to settle little ones rather than wind them up. No harsh flashes, no sudden loud noises. Just gentle, soothing play.
HAND IT OVER WITHOUT WORRY
Tap Start and the screen locks to Rattle Worlds. No accidental calls to grandma, no messages sent, no photos deleted, no settings changed — little fingers simply can't leave the app. (Guided Access on iPhone & iPad.)
A RATTLE YOU CAN FEEL
Every world answers to touch, with rich, tactile sensory play:
• Multi-touch — every finger leaves a trail; little hands can play all at once
• Draw on the screen — swirl light and color with a fingertip
• Ripple & parallax — the world splashes, bends and shifts under each touch
• Shake it — give the phone a wiggle to trigger special animations and playful surprises, just like a real baby rattle
• Familiar nursery rhymes — soft instrumental versions of well-known melodies, with gentle sound effects
• Lights in sync with the notes — the world lights up in time with the melody, note by note
• Haptic feedback — soft taps your baby can feel
LITTLE WORLDS THAT QUIETLY TEACH
As your child grows, the same play begins to teach. Tap letters, colors and shapes to hear their names spoken aloud:
• Letters — meet the alphabet, one friendly character at a time
• Colors — name the colors, then mix them and watch brand-new ones appear
• Shapes — circles, squares, triangles and more, as playful things to touch
And simply beautiful places to wander — drift among the stars, float through the ocean, roam a sunny garden, and celebrate the seasons in cozy Easter, Halloween and Christmas worlds. Touch and hold an empty spot and a portal opens to the next one.
MADE FOR PARENTS, NOT ADVERTISERS
• No ads. None. Ever.
• No tracking. Nothing about you or your child is collected — there's simply nothing to collect.
• Hand-crafted, gentle visuals, soft on the youngest eyes.
• Works beautifully on both iPhone and iPad.
Give your baby a whole world to explore — and keep your calm, wherever you are.
WORKS ANYWHERE — NO INTERNET NEEDED
No Wi-Fi, no signal, no problem. Everything runs fully offline, so it's ready on the plane, in the car, underground, or far off the grid. Switch on airplane mode and it still works beautifully.
