Cross-platform GTD
OmniFocus for Windows: the alternatives
Last updated:
You know OmniFocus is the most powerful GTD app available. You also know it doesn't run on Windows. No native app. No plans to build one. If you use a Windows PC at work — or anywhere — here's what actually works.
Why OmniFocus users look for Windows alternatives
The Omni Group has been explicit: OmniFocus is an Apple-ecosystem product. Their development priorities are Mac, iPhone, iPad, Vision Pro, and a companion web app. Windows and Android are not on the roadmap and never have been.
Ken Case, Omni Group's CEO, said it plainly: “Developing new features isn't the top priority of our web team. Our web team's top priority is to keep the service running efficiently and reliably.”
The web app does exist — and it's more capable than many realize. It supports defer dates, sequential projects, custom perspective viewing, and full task editing. But it lacks search, review mode, perspective creation/editing, and mobile optimization. It's a companion, not a replacement.
“Thousands of people having to run two separate to-do list manager systems is what marketing experts call ‘an important but unmet customer need.’” — mwooten777, Omni Group Forums
The Windows user's GTD problem
If you're a GTD practitioner who uses Windows at work, you face a specific set of challenges:
The mixed-ecosystem problem
You have a Mac at home, an iPhone in your pocket, and a Windows PC at the office. Or your company issues Windows laptops with locked-down IT policies. Your GTD system needs to be available in all of these places. OmniFocus works in two out of three — and the web app fills the third partially, but without search or review mode.
The corporate IT problem
Many corporate Windows environments restrict App Store access, block personal devices, and limit which software can be installed. A web-based app that runs in any browser — Chrome, Edge, Firefox — works within these constraints without IT approval.
The workaround problem
OmniFocus users on Windows have tried everything: propping an iPad next to the PC, renting a virtual Mac via Remote Desktop ($25+/month), emailing tasks through Mail Drop, running two separate task systems. These workarounds add friction — and friction kills GTD habits.
“Leaving OmniFocus was probably the hardest technological decision I've ever made. I can't afford being in a vendor lock-in with Apple.” — OmniFocus power user, Hacker News
The alternatives compared
Here's how every cross-platform option compares to OmniFocus on the GTD features that matter most.

Each option, honestly
Todoist — cross-platform, but not GTD
Todoist has a native Windows app with the best NLP input of any task manager. But no defer dates, no sequential projects, no review mode. If GTD is your system, you'll spend your time building workarounds for features that should exist natively. $60/year after the December 2025 price hike. See Todoist vs SingleFocus.
TickTick — feature-rich, GTD gaps
Native Windows app, $36/year, Pomodoro timer, Eisenhower matrix, habit tracker. Good general-purpose task manager. But start dates require an end date (not true defer dates), no sequential projects, no review mode. Privacy-conscious users note Chinese data storage.
Nirvana — the closest GTD match
Native Windows app, purpose-built for GTD with sequential projects and true defer dates. $39/year. Still actively maintained as of 2026. The closest thing to OmniFocus's GTD fidelity on Windows. But no custom perspectives, no review mode, no API, and a utilitarian interface. If strict GTD methodology matters more than polish, Nirvana is worth trying.
SingleFocus — full GTD on the web
The only cross-platform app that combines defer dates, sequential projects, custom perspectives, and a built-in weekly review. Runs in any browser on Windows, macOS, Linux, Android, iOS. ML-powered focus mode, energy lens filtering, gentle language for cognitive load reduction, REST API with 34 endpoints, MCP for AI assistant integration. Free during early access; $36/year for early users at launch. PWA rather than native — installable for offline access but browser-based.
The honest trade-offs: native depth vs. cross-platform access
OmniFocus is the most powerful GTD implementation ever built. That's not disputed. Omni Automation, Apple Shortcuts, the depth of perspective configuration, per-project review intervals — these are features no cross-platform app fully replicates.
But GTD's most fundamental principle is ubiquitous capture. David Allen is explicit: your trusted system must be available everywhere, all the time. If you can't capture a thought from your Windows work PC at 2pm, it either gets lost or you build a second system — and a second system means you no longer have a trusted system.
The question isn't “which app has more features?” It's “which app can I actually use consistently, on every device, without workarounds?”
“The pain of running 2 separate GTD universes was greater than not having a desktop client.” — psidnell, Omni Group Forums
