I just downloaded the app thinking it would be a great addition to my ELL classroom. When I launched the app, it says it's searching for a router. I'm connected wirelessly to my home network, yet that doesn't seem to be what the app is looking for. In the description, it doesn't list any external components needed to utilize the advertised features, only showing an iPad, iPhone and the iOS needed. However, in the image provided, there seems to be a camera or something similar on a stand. I'm assuming that is needed to make the iPad into the scope being advertised. However, when I went to the website there is nothing listed for the app, nor equipment listed as needed to make it work. Is there a device that is needed for this? If so where do I find it and how much is it? Why isn't that information included in the app description? As it is, it's completely unusable. I'm extremely disappointed and would not recommend anyone downloading this app until and unless more information is provided.
