After that, I created a high-fidelity prototype for a mobile phone (left), an iPad (below), and a website (below). Based on the results of my usability studies, I made it clear on the home page that this app is designed for teenagers. I also added a message ensuring users that their private information will not be published. In addition, I gave users options for the picture they use to represent themselves. Finally, I added a message thanking users for signing up.
