The idea is that you add tasks to an inbox quickly as they occur to you, then schedule them, add reminders, and assign them to specific lists or colleagues. Wunderlist is loosely based on the Getting Things Done methodology. If you pay for a Pro subscription, you can even allocate tasks to others.

Add a note to a task and you can discuss it with co-workers and family members from within the app using the conversations feature. Lists can be shared with other Wunderlist users and when one of you ticks off a task as being completed, the other’s app is updated. Add a task on your iPhone, pick up your iPad, launch Wunderlist and there it is. If you use Wunderlist on, say a Mac and iPad as well as an iPhone and sign into your account on each device, syncing takes place immediately. But it’s syncing and collaboration where Wunderlist really excels. You can also comment on and attach files to tasks. As you would expect, you can create multiple lists, add tasks, schedule them and specify when you want to be reminded to complete them.
