Needs improvement

Another reviewer already mentioned the problem with the figures. This is the first application I have purchased for iPhone that would allow viewing of the figures. I wasted a great deal of money on others only to find that they required flash players. The information in this tool is useful but it is always better to see what they are talking about. It's too bad they did not take advantage of the touch screen size control of the iPhone. I think all the one star reviews are from people who do not know how expensive reference books are. This is not a toy. If they can improve the figures and maintain the quality of information, I will continue my subscription indefinitely.
