For agile story tracking and development pipeline management, Pivotal Tracker. Lots of great features for team productivity and health tracking, also helps as you automate your workflow. For general tasks and individual workflow, Trello. By far my favorite UI and delightful experience in using for simple workflow management using a kanban style (which plays a large role when you use it regularly). Trello is less useful the more team members that join and the more complex the workflow you need to manage.
