A see-through body kids can tap: 12 hand-drawn organs that beat, breathe and ripple, each with its name, its job and a real fact — free, no sign-up, no ads.
Try it Free →Brain, eyes, heart, lungs, liver, stomach, kidneys, small and large intestine, pancreas, bladder and nerves — drawn as real anatomy in soft, friendly colours, never emoji stand-ins.
The heart pulses, the lungs expand and shrink on a four-second breathing rhythm, the stomach churns and the intestines ripple — so kids see a body at work, not a diagram.
Tapping an organ lights it up and fades the rest, then slides up a card with its name, a one-line job description, a real number and two bite-sized facts.
One tap on a system pill — breathing, food, blood, nerves or water — keeps that team bright and dims everything else, making body systems obvious at a glance.
Organ homes turn into dashed outlines and six shuffled organs wait at the bottom. Drag each one back: right answers snap in with a glow, wrong ones bounce back with a kind nudge.
Every organ you meet is counted toward 12, saved on your own device, with a confetti celebration when the whole set is collected — plus a best time for the game.
Open the page and a see-through human figure appears with all 12 organs in their real positions. Tap the beating heart or any other organ to zoom in on it.
A card slides up with the organ's name, what it does, a real measurement and two fun facts. Swipe left or right, or use the arrows, to browse organ by organ.
Tap a coloured pill at the top to keep only one system bright — breathing, food, blood, nerves or water — and see which organs belong together.
Tap the puzzle button, then drag each of the six organs from the bottom row into its empty outline. Finish the set to earn one to three stars.
