Things 3 is a macOS / iOS task management app released by Cultured Code in 2017, "2017 Apple Design Award Winner (Source: Apple Newsroom)" . With its "do less" design philosophy, it has become a long-recommended tool in the GTD (Getting Things Done) community. Pricing is $49.99 for macOS, $9.99 for iPhone, and $19.99 for iPad—all one-time purchases. What makes it most distinctive isn't the breadth of features, but its "Today / Evening / Anytime / Someday" four-tier time architecture, which precisely corresponds to David Allen's classification of task time-sensitivity in the GTD methodology. This means users don't need to design their own categorization logic—they can run the complete GTD workflow out of the box.

"David Allen proposes the five GTD steps: Capture, Clarify, Organize, Reflect, Engage (Source: Getting Things Done Official Website)" , and Things 3's interface design maps these five steps almost one-to-one onto the app's structure: Inbox corresponds to Capture, Today/Upcoming corresponds to Organize, Areas/Projects correspond to Clarify, and Logbook corresponds to Reflect. Most task management apps (such as Todoist, TickTick) take a "feature stacking" approach, providing tags, priorities, subtasks, kanban boards, Gantt charts, and many other options, leaving users to decide how to use them. Things 3 goes the opposite way—it removes the priority field, removes color labels, removes the status field, and only retains four dimensions: "Date," "Area," "Project," and "Tag." This restraint prevents users from falling into the "over-organization" trap. According to "The Wikipedia entry on the GTD methodology records that since its publication in 2001, more than 2.5 million copies have been sold (Source: Wikipedia)" , demonstrating its long-term influence, and Things 3 is currently one of the few mainstre
