Things 3 for Windows
Things 3 does not run on Windows. Udle does.
Things 3 is one of the best-designed planners ever made, and it is Apple-only by deliberate choice - no Windows app, no Android app, no web version, and Cultured Code has said for years that none is coming. If your work machine runs Windows, the usual answer is to give up the calm structure you liked. Udle is a full planner in any modern browser, with the same areas-projects-tasks shape.
| Compare | Udle | Things 3 |
|---|---|---|
| Windows support | A full planner in any modern browser on Windows, plus a desktop app | None - Mac, iPhone, Apple Watch, iPad, and Vision Pro only, with no version planned |
| Planning model | Inbox, projects, folders, subtasks, tags, defer and due dates, perspectives, weekly review | Areas, projects, headings, checklists, tags, and the Today, Upcoming, Anytime and Someday lists |
| Habits + planning | Native habits, focus sessions, and rewards share one model with tasks | No habit tracking; repeating to-dos are the closest equivalent |
| Motivation | Optional idle RPG that pays only for real upkeep, with Quiet mode to turn it off | A deliberately calm, un-gamified interface |
| Automation | Personal API tokens and a global CLI for agents, Codex, Claude, and OpenCode | Shortcuts, a URL scheme, and AppleScript on Mac |
| Price | Free plan; Pro is $4.99/month or $49.90/year | One-time purchase per Apple device class: about $49.99 Mac, 9.99 iPad, $9.99 iPhone |
| Best fit | People who want Things-style calm on a PC, or across mixed hardware | All-Apple users who value design and a one-time price above breadth |
The honest short version
If every device you own is Apple, buy Things 3 - it is beautiful and has no subscription. If any machine in your life runs Windows or Linux, Udle gives you the closest equivalent structure there, adds habits in the same system, and never charges per device.
