Body Maps, a collaboration between General Electric and Health Line is taking human anatomy social. The users can explore the human body through over a thousand 3d renderings of body parts, and over 200 videos covering different medical conditions and procedures.

What makes Body Maps social, is that the user can annotate images by drawing on them with their finger and share the results via Facebook or Email.

According to James Hambling, MD, the health channel editor at The Atlantic — this is “the best basic anatomy resource” he has ever seen. It “provides easily digestible anatomical information, it’s intuitive to navigate structures across multiple planes,” and most importantly, its “visually and symbolically on point.”

It’s available for $8.99 in the App Store.
