Improve UX by watching how users organise information
Ballpark card sorting is a simple, hands-on way to see how people naturally organise information. Participants sort labelled cards into groups that make sense to them, giving you valuable insights to create a structure that feels intuitive and easy to navigate
So rad! I made a similar app in 2004 (in Flash, it was called MindCanvas). Don't get sucked into building generic survey features, sick with the special question types you have developed is my advice. Ballpark looks really great.
