The purpose of the project is also to allow people to communicate about the books through the application and so create a community. In the future, our application will also be released on other platforms so we are not only iPhone developers.

The market that we are targeting is the eBook market, including the persons who read them and companies that sell them.

We are looking for 9 icons that will be visible in the main screen of our application. The icons must be well designed with a fresh style so feel free to express your creativity.
