Wunderlist is a free, cloud-based task management application that allows users to create lists to manage their tasks on many devices, mobile as well as desktop. These lists can be shared with other Wunderlist users, can have due dates, reminders, assignees, subtasks, comments, files and notes to tasks (all of which can be organised by #hashtags). The user adds lists to categorize tasks, and can place these lists in folders to organize their structure. By combining to-do lists, and multiple calendars under one simple, easily navigable platform, Wunderlist encourages a routine, and a commitment to consistency, while minimising time spent and cognitive cycles (since everything is on one platform). Its built in triggers (reminders, deadlines, various categories) also ensure a high ability to perform.
