In Upwave, there are two types of templates; Task boards and Strategy canvases.
A Task board is simply a board used for tasks. Cards in a task board represents pieces of work to be done, which requires different actions. Cards in a Strategy canvas, however, act as containers of information with no specific action required. An example of a task board is the traditional Kanban board.
Since it requires an action, a card in a task board have more options than a card in a Strategy canvas. You can both assign, set due dates, change colors, create subtasks, complete, comment and upload files. Read more about cards here.
