Lite version pretty much useless....
Great app but this version only has 8 positions. This app will leave you wanting more. The full version was intially $19.99, then went on sale for $9.99 and is now $24.99. This is a great handy reference to have when you have time in between procedures. Depending on what you think app of this nature is worth, it will probably go on sale again. When you are ready to spend some money get the full app.

Love it
I am an xray student and this app is very helpful for studying and even to just refresh the memory of rarely used positions.
