AtTask provides a group project management platform, based on Gantt charts, with a variety of reports and dashboards available to help managers keep track of how things are going. It also offers tools for organizing teams to tackle projects, including the ability to run what-if scenarios to see how assignments will affect everyone's workload. Part of AtTask is TeamHome, a workspace for team members to take on tasks, see what they have to do and what's next, and have access to a communication stream to keep informed about what everyone else is doing. AtTask for the iPhone (free) is a portable version of the TeamHome workspace. It lets you manage work requests and see information about your assignments. You can access updates from teammates and comment on them as well as get notifications when they comment on yours. And you can log the time you spend on each task and let people know when you think you'll be finished.
