TripScout produces high quality audio guides and offline maps with a quirky twist that I really appreciate - they cover the highlights you'll obviously want to know but also slightly more obscure points of interest. I don't get to travel as much as I'd like to anymore but have also found the guides to be fun armchair traveling - I can learn about cities I'd like to visit someday.
