Decided to go ahead and purchase this to have on my iPad. And as a former librarian, I very much respect and appreciate intellectual property (although open access and Creative Commons are always preferred). The materials themselves are good, so not a huge regret, but the app leaves much to be desired. It’d be great if I could create and store multiple slideshows (either within the app or on export), but no such luck as far as I can tell. You can export single images, but not a curated set. And you can’t combine visuals from the sections into a slide show, either, which means this is essentially useless in an actual session. The draw function isn’t working at all, which is really frustrating, too. And why is “resources” just a calculator? The iPad actually comes with that.
