Specs
Pros
Pro Detailed control over tasks
Wunderlist features the standard ability to add tasks and organize them within lists, but one of the aspects in which it excels is the amount of detail and control that can be put into each task. Rather than the task just alerting you, it can be set to do many things such as reminders, sub-tasks, notes and recurring tasks.
Pro Can add to your list via email or Google Now
If you're on the run or away from your device, you can add items to your list by email. You can also add notes to the list item using the body of the message. Wunderlist supports Google Now, meaning you can add to your list using native voice commands on Android.
Pro Simple, useful task management features
Wunderlist features the standard ability to add tasks and organize them within lists, but one aspect in which it excels is the amount of detail you can add to each task. Rather than simple alerts, tasks incorporate a number of other options, including reminders, subtasks, notes, and recurring tasks. You can also star important tasks, which is simpler than the priority systems used in many other apps.
Cons
