Omnifocus for Mac costs $80, while the iPad and iPhone versions cost $40 and $20, respectively. Omnifocus will sync all of your tasks across different devices, but you’ll have to pay to install them on each one.

But it is available only for the Mac and iOS devices. Omnifocus helps you organize your inbox, schedule, and workflow. The good news is that there’s a fair amount of instructional and user-generated setup documentation/videos.” Donald McMichael told me “Omnifocus is powerful and highly configurable from a process standpoint, and thus has a somewhat steep learning curve. People brought up OmniFocus a number times over the course of my informal survey. It’s important to point out that the apps, software, and processes mentioned below aren’t necessarily the most popular in the industry they’re just the ones that users have recommended based on their own experiences. Like most of you, I’d rather rely on the experience of real users than on a review I’ve read in some app store. Most people have come around to realizing that they must track their commitments and workflow in order to keep things from falling through the cracks, and that often means selecting GTD apps–but it can be tough to sort out the wheat from the chaff in the crowded GTD space. These principles center around the creation of a workflow process and the tracking, storing, and monitoring of tasks that one needs to accomplish. After the book came out, numerous software apps sprang up to help people apply GTD principles.

Productivity consultant David Allen popularized the Getting Things Done (GTD) method in his 2002 book Getting Things Done: the Art of Stress-Free Productivity.

I asked a random selection of real-world users what their go-to GTD apps were, and the results surprised me: No one used any single tool in a vacuum, but rather used a combination of software and applications to get things done. Getting Things Done (GTD) apps are becoming de rigueur for anyone who needs to manage their time, from small-business owners, to employees, to CEOs. Author David Allen conceived of, and popularized, the “Getting Things Done” (GTD) concept in his 2002 book.
