For now, the plan is pretty straightforward: To make really simple, interesting travel guides, designed first for the iPhone and iPad, and sell them. Our goal isn’t to rehash Wikitravel or display 300 touristy dumps on a map. We want to help you find the best and most interesting places in a city, not the most famous or most obvious, so you can have a great time.
