Is Wunderlist free?
Wunderlist is free to download and use, but some of its features are limited unless you get a paid subscription. For instance, you can only upload files of a certain memory size to Wunderlist, delegate a limited number of tasks in a shared list, and break an objective down into a limited number of sub-tasks.
File size limit: 5 megabytes per file
Delegation limit: 25 "to-dos" per shared list
Sub-task limit: 25 sub-tasks per "to-do"
Background limit: 20 wallpapers for customizing Wunderlist
Wunderlist Pro / Wunderlist Business*

File size limit: none
Delegation limit: none
Sub-task limit: none
Background limit: 30 wallpapers for customizing Wunderlist
*Wunderlist Business offers basically the same features as Wunderlist Pro. However, it allows you to group the subscription costs for each employee in your business who uses Wunderlist into a single invoice (instead of each employee having to pay for their own subscription). It also allows you to add or remove team members as necessary, and downgrade the subscriptions of all employees to Wunderlist Free at once, if your team or its needs change (respectively).
That's a breakdown of the costs associated with using Wunderlist!
