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).
Nice
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.
Good
Nice app but it lacks of contents.
Very nice
:)
Looks good so far
Good app, great prospects
