OmniFocus 1.0 represents a long-awaited addition to the GTD offerings on the Mac. It's a GTD-compatible task manager that has been in beta (or vaportrail, as they call it) for a while now and has gained an active community of users. Today's release puts Omni ahead of several other developers, which may help make up the minds of the more impatient GTDers who have been watching the options grow more varied and the spread of features get more convoluted.
Omni nailed a few things in this application, including a very powerful means of managing how tasks are viewed (focuses), recurring tasks and OS X integration that includes Spotlight indexing of tasks. The interface is unfamiliar to new users, but relatively intuitive. And, unlike some of the other up-and-comers, Omni made GTD standards a high priority. Whether that is a selling point depends entirely on the individual user's taste.
OmniFocus has updated almost every day since I got my invitation to the beta some months back. If you like applications that have a quick and responsive development team, you'll enjoy the development pace. It's retailing at $79.95 now that the pre-order discount is finished.
