Judge Arkansas STEM Festival app for iPhone and iPad

This application aims to increase the interaction between visitors and project presenters. At the Festival, each project is assigned a unique QR code. Visitors are expected to scan the QR code through this app and answer one true/false question about the project and hit either "Like" or "Neutral". As a result of these interactions, project presenters and visitors will earn points. The visitor and the project presenters earning the highest score are going to be awarded Apple Watches.

The Arkansas STEM Festival wants to achieve the followings with this app:
Ease the judging process.
Increase the interactivity between presenters and visitors.
Provide a tool for visiting schools to evaluate their students engagement at the Festival.
Collect feedback from visitors.
