I recently purchased the apps for cities Zürich, London and Paris. I emailed the company because my wife wanted to view the PDF files which they said within 12 hours they would be happy to send me the links for. That is an amazing response time for a small company. I am going to the cities in March and look forward to extensively using these apps both on my iPhone and in PDF format for my wife.
