Modality, a company out of Durham, North Carolina, produces learning software for medical students, and healthcare professionals. They feature a large suite of software titles designed to be viewed on the iPhone (Windows and Mac versions available too, it looks like).
From Modality Netter’s Anatomy product page:
Using outstanding anatomical illustrations from Netter’s hugely popular Atlas of Human Anatomy (4th Edition), Netter’s Anatomy allows you to carry the bestselling reference for human anatomy on your iPhone or iPod touch. Navigate through images with the flick of a finger, pinch to zoom, and tap to test your knowledge of muscles, bones, vessels, viscera and the joints. Use study mode to explore images at your own pace and quiz mode to test yourself on what you know.
The concise text reviews areas of origin, insertion, action, innervation, and anatomical relevance. The notes also include clinical correlations, where appropriate. A regional organization parallels Netter’s atlas as well as most of today’s anatomy courses.
