Headquarters

Headquarters is an iPhone app for Basecamp (this means that you have to be a Basecamp user for Headquarters to have any value). The app itself offers almost all of the Basecamp feature set. With Headquarters, you can add tasks, manage to-do lists, set milestones, compose messages, and view files. The interface is very well designed, and Headquarters truly captures that native app feel. Basecamp does have a site optimized for mobile use, but that’s the closest alternative.
