We built Cluster Cards - insightful, action oriented card deck for problem solving - for the Sencha Touch App contest. Our app did not make it to the Top 10. It's not a great example of Sencha Touch's capabilities or HTML5. Nevertheless, I feel it has the potential to help many people.
We built the first version as a tool for conference participants (image all people going to Sencha Conference) to get maximum value of their participation. We have only created seven cards right now, but will add more soon. We were inspired by Get Mental Notes and believe such cards are a great way to solve problems.
I would like to get your feedback on the app and the idea!
