You think tiny little pocket computers are complicated feats of engineering? They’re nowhere near as advanced as the human body, which is by far most complex thing known to man—and everyone owns one, too, so we’re all in the same boat. But do you even understand how things work, or care? Tinybop’s new app, Human Body, is designed to teach you all you need to know. Because it’s important we keep our bodies in top working condition; it’s not like we can just go out and get better specs.

Aside from having some wonderful art and animations, the $3 app is designed to allow users to fully explore the human body. “Every part is animated and interactive: the heart beats, guts gurgle, lungs breathe, the skin feels, and eyes see,” the app’s description says. It’s fun and educational, and should appease the curiosity of folks of all ages. I’ve always found the human body so fascinating, but health books in high school were never the most entertaining. Human Body is designed to make exploring your insides (not your feelings) entertaining.

Above all, Tinybop’s app is meant to be an interactive experience, with six animated layers of the body that teach basic human anatomy, with skeletal, muscular, nervous, circulatory, respiratory and digestive systems all represented. Want to know about the heart? Tap it, and Human Body will tell you all you need to know. Tinybop is marketing its app to the younger crowd, but it offers enough to capture the interest of adults, too. The app even comes with a recording mode, which enables parents and kids to ask each other questions.

Tinybop says there are no gaming elements to the app, and encourages curiosity. For $2.99 (iOS only, available for the iPhone, iPad and iPod touch), this is the kind of thing that demonstrates why technology should be utilized in the classroom. I wish I had stuff like this when I was growing up. There are already scores of similar apps like this, but none are quite as nice to look at—or as cheap.
