The challenge with the Pinwheels for Prevention iPhone App was finding a way to get people interested in the campaign. It was important that people found some kind of joy when using the App that would in turn led them to wanting to learn more and share with others.
My solution was to allow the user to interact with a digital pinwheel and be able to share the pinwheel. Also in the App it was important for the user to have the option to learn and the option to donate. That way they were not pressured into anything, but were given an option to help.
