The whole world is moving to a mobile world. Therefore, one should go into account with the mobile devices. These mock-ups are made for mobile platforms. Here we had to start thinking about a mobile application that we would like to work out in mock-ups. My application is "Where the party at?". The application works a little like Shazam. When opening the application, the user gets a big button and a slider. With the large button, the application go searching to all parties in the distance around the user. The distance can be set using the slider. Further screens of the application can be viewed at Behance.
