Wunderlist is a free task management service that syncs across all of the devices that you use. If you're like me and you use an iPad, an Android phone, and the web throughout your day you'll appreciate that Wunderlist works the same way on all platforms.
Creating task lists in Wunderlist is an intuitive process. Just click the "new list" button and start typing out your list of things to do. You can create as many lists as you like within your account. You could create a list of things to do at home and things to do at school. Or you could create lists for the week, the month, and the year. You can set a due date for each task in all of your lists. All lists can be shared if you would like others to access them.
Applications for Education
As I've said in the past about task management tools, they're only good if you actually use them. Wunderlist has a clean, intuitive interface that makes it easy to use. If it's easy to use students could be more likely to make a habit of using Wunderlist to keep track of their assignments.
