Flook was a location-based browsing application and website developed by located in the United Kingdom, initially for the iPhone. Users of the application created virtual cards, or "Flooks", which were made up of a photo of a particular location and a small piece of text describing that location. These Flooks were then recorded with their geographic coordinates so that other Flook users could see where they have been posted when they are using the app. Users typically upload local secrets, places to go and things to see. The application was therefore a wiki of sorts, but was also a combination of Google Maps, StumbleUpon and review websites such as Tripadvisor or Toptable.
