Runn doesn't have a card view. Runn has been designed for higher-level project resource planning and helps you answer questions like, "Who and how much time do I need from people to deliver a project" or “When does Peter become available again to work on a new project”.
Most of our customers use a project management tool or scrum board, such as Jira, Trello or Asana alongside Runn to manage the project details.
