WUNDERLIST Screen Shot 2014-05-10 at 10.18.25 PM If your like me im always open to trying to tools that will help streamline my productivity and Ive been looking for a good task manager or to do list app that is free, that can handle sub-categories of to do lists and syncs with my i-phone and macbook. Finally I found a really good one called Wunderlist. If you make a lot of to do list for stuff. its really clean and easy to use.
