I'm doing something similar for local news/events, called SeeAround.me, where people can see/submit local news stories and their locations. But I could see sort of a cross between that and Your Audio Tour as particular interesting for people who want to do their own walking tours, for example.
Project: SeeAround.me - an app to see and share hyperlocal news by location (like Waze for what's happening nearby). All content is user generated, with most of it in San Francisco, Oakland, and Berkeley for now.
Frustration: It's hard to see what's happening near you based on your location (hyperlocal news, events, restaurant openings/closures, construction, etc.) Local news is distributed across so many sources, and it's not easy to see where exactly stories are taking place.
In the U.S. we force children to sit still through hours of classes, wonder why they get distracted, and then medicate them. In other countries kids get more breaks to expend energy and are then more attentive - e.g., http://www.theatlantic.com/education/archive/2014/06/how-fin... "In every one of the experiments, students were more attentive after a break than before a break. They also found that the children were less attentive when the timing of the break was delayed—or in other words, when the lesson dragged on."
