Its just okay, not great like the skeletal app
The app navigation is very counterintuitive. I cannot stand that it has you zoom by double tapping instead of spreading fingers like in everything else on the iphone. Also every time you change to a new muscle it says "...loading..." Totally unacceptable for a 4$ app. Please fix these things and make it more like your skeletal anatomy app.
