Its a great product with a rich set of features. Taskworld helps us to get good feedback's from our clients as we can effectively manage our projects.
Customer service is great and responsive and personable, which in this day and age is always a very big surprise and great selling point. Totally inexpensive - for mid-range features.
I love it, much easier to use than Wrike, more fun to do so. I also like Trello - but I have more control with task world on the next steps, and I can see the finished tasks with one click.
There seems to be some really bad issues with the screen not refreshing (I guess that's what it is). Many times I will be in a screen and parts of the screen will disappear.
QA seems to be lacking, features break without warning and working around until they fix it is difficult at times.
No status of a project, besides general terms. The overview shows graphs and charts that are useless and cannot default a view without them.
