Trello is an app used for collaboration and project management. Trello allows users to create virtual boards to manage their workflow, and then customize those boards by adding lists and cards. Users can also attach files, checklists, and comments to the cards to help keep all aspects of a project organized and on track. Trello has an intuitive user interface, which makes it easy to use. The boards that are created can also be easily shared among a team. A student working on her Adult Diploma, for example, could create a board and share it with her teachers in order to get virtual feedback and support.
