Serendipitor

Found this in the app store (on KTs rec) and have installed it on my phone. Looks like a lot of fun, but maybe not suited directly to our project.
I think we could make our own app (when we find our how) to map our own journeys and adventures.

Free in the iTunes Store.

Serendipitor is an alternative navigation app for the iPhone that helps you find something by looking for something else. The app combines directions generated by a routing service (in this case, the Google Maps API) with instructions for action and movement inspired by Fluxus, Vito Acconci, and Yoko Ono, among others. From the Serendipitor website.
