Herdr is an app created for WWF that works the same way as Tinder, but with a twist. The user opens the app with the belief that it will give them the location, information and photos of their chosen animals by swiping left for no and right for yes, After the decisions have been made it will take them to a screen where their choices have been collected and the information should be given, but it won't be. Instead, all their choices will turn up red as if they hadn't "liked" them. The app will act like their choices are there and taken them to the final screen where they are greeted with a message that states they cannot see their chosen animals because they're dying out with the line "whether you like it or not" and a "tap to donate" feature. This idea is campaignable and could be used not only in app form but on a website or possibly even banner advertising.
