I liked the ability to assign tasks and monitor due dates best. It was user friendly and there was a free version. Review collected by and hosted on G2.com.
When I was using the app there was no option for the subscriber to control adding and deleting team members. People come and go and I stopped using what was a good tool because of my inability to delete people and tasks from my team view. Hopefully they've made some feature enhancements.
