I think first order of business might be to replace the examples on the landing page to realistic ones. Not only will it communicate the idea/value much more clearly, but i think constantly using realistic examples can help you flesh out realistic issues that might not be obvious otherwise.
This is an interesting point. Also one I struggled with. I could either use an 'example' of this concept, or I could use it to do screenshots.
Based on the way the page is laid out, I didn't want to clutter it with another section of images for the screenshots - if I chose to use an example.
I wanted absolute clarity so viewers could easily grasp the purpose of the app. As a result, I didn't want to clutter the page too much. So I decided to go with one.
But you are right, maybe having an example would make it more obvious...but then I can pretty much guarantee that people would ask for screenshots - at which point, how do I solve that issue without crowding the page?
That was my train of thought where that was concerned.
