It's okay, I was buying it so I could experiment with the complex systems builder, a lot like the complex systems in the manual section. Unfortunately complex systems don't seem to be able to be made (i.e. have a separate rope pulling part of the system).

Overall this is a good app. However the list of devices to choose from in the mechanical advantage systems builder are only the Petzl ID. I work on a ID however have a sparrow for rescue as it has a much lower friction ration to the ID. Would also like to see some other devices thrown in just for fun as well.
