Flook is a new mobile app that is described by the ones who created it as a serendipitous discovery engine. That sounds a bit meretricious to me.
It is an app that you can use in order to discover more about the world that surrounds you. This is accomplished by browsing through cards with a photograph and some text for geo-locating purposes. The system learns as people use it – it takes notice of which cards are more popular, and then it displays these first.
Flooks can also be shared a la Twitter. That is, you can use this service to geo-locate your tweets and add photographs to them. In that way, you will be coming up with flooks of your own for everybody to take a good look at and eventually discover in real life.
I think that the most suitable way to describe this site would be terming it as something like StumbleUpon for places. The best thing about Flook might just as well be that you can procure it for free. And the top users are highlighted in the provided ranking, so that if you have a competitive streak this app will let you revel in that as well.
Flook.it In Their Own Words
“Flook is a location browser – the world’s first Serendipitous Discovery Engine. Flook is a brand new way to discover and share the world around you. Flook’s innovative UI lets you simply swipe through a stream of nearby flook cards. Cards have a full-screen photo and some text and they’re also geo-located – placed at a specific location for you to find when you’re nearby. Over time, flook learns which cards people like most, and then shows them to you first.”
