The only disappointing feature comes in the form of application functionality. Since there is so much graphical detail, some of the body part tags are small and hard to read. In some pictures, like the one below, tags litter the screen and make the picture below it hard to see.
Navigating through the menu structure is often confusing and laborious. There is a help section, but it falls short on delivery and content as well.
The application is a fun way to learn about the body, and will be an educational experience for your kids. Those looking for more detail and deeper explanation into the body will find this app a bit elementary.
Overall, I found The Human Body to be a fun app for parents and an entertaining app for kids.
