Great app with one very annoying design flaw that costs one star. I’m a doctor and longtime college educator teaching Anatomy and Physiology. I love this app. What I don’t love is the information box that pops up every time I select a bone or muscle or other piece of anatomy. The information is great, but there should be an option to disable the popup to allow an instructor to quiz students without the answer appearing on the screen. The info box also superimposes itself over important structures, and must be moved manually every single time to view the anatomy. This is very irksome when moving from structure to related structure. My recommendation to the developer is to provide an option in the Control menu or Settings to toggle the popup info box on or off, and also a second option to allow ‘fixing’ the info box to a particular location on the screen so that the info box, when toggled on, doesn’t overshadow the anatomy in the middle of the screen. In other words, provide an option that would let you place the info box in the upper left-hand corner of the screen, where it would stay put until moved to a different screen location. Fix this well-intentioned info box from hades, and you’ve got my vote for five stars!
