Not so free... To view/read most of the content, you'll need a "full version" at 5$. Navigation within the app is OK but not great, most of the content is copied from Tripadvisor. Wouldn't advise it to my friends.
Useful I found this guide really helpful, especially the free map with pins of attractions and listings.
