The Human Body Lab by Tinybop

Your watch is a window into your body.

Jump, run, and shake to see your skeleton move and your heart rate speed up in real time as you explore your own anatomy and discover how it works!

Dive inside a living, working body where the heart beats, lungs breathe, guts gurgle, and signals race along the nerves. It's a pocket-sized science lab built for small screens and big curiosity.

Explore every system. Tap through the body's major systems and watch them come to life:

** Circulatory — see your heart pumping and responding to your movement
** Respiratory — breathe in, breathe out, and see the lungs at work
** Digestive — feed the body and follow a snack from start to finish
** Skeletal — meet your bones and watch them move as you move.
** Nervous system — peek inside the brain, see how the eye sees, and watch sound travel through the ear
** Skin — discover the body's largest organ and how it senses the world

Your body, your way. Choose an avatar to make the lab your own, then learn how a body just like yours moves, breathes, and grows.

Move to learn. The Human Body Lab turns your watch's sensors into hands-on science. Get up and run to watch your heart rate climb. Slow down and breathe to see your lungs respond. Real movement, real reactions — learning you can feel.

Sensor Specifics
-We use the HeartRate sensor to demonstrate your heart rate and lung function.
-We use temperature sensors to demonstrate relative hot and cold's effects on the skin
-We use movement and step sensors to demonstrate how muscles and bones interact and show stats.
-Human Body Lab is not a fitness app, but rather an anatomy and mindfulness educator. We show you your daily stats and give them context. Only you have access to your stats.

All sensor data is kept on device. It is never transmitted to us or any third party for any purpose.

Fun facts at a glance. Did you know your heart beats about 100,000 times a day? That there are hundreds of millions of tiny air sacs in your lungs? That a message from your brain can travel faster than a race car? The lab is packed with surprising, kid-friendly facts that make great conversation starters.

Made for kids, trusted by grown-ups. Like every Tinybop app, The Human Body Lab is built for kids to develop foundational science literacy and a lifelong love of learning. There are no rules, no scores, and no wrong answers — just open-ended exploration that rewards curiosity.
