Things 3 alternative for Windows & Android

What you lose (honestly)

Cultured Code, the makers of Things 3, have been explicit: Things is Apple-only by design. Their support page states that Things will NOT work “on the Internet (through a web browser).” No Windows app. No Android app. No web interface. Not planned, not coming.

This is a deliberate choice, and there's a good argument for it — native apps on Apple platforms can be deeply polished in ways that cross-platform apps can't. Things 3 proves this with its animations, haptics, and platform integration.

But if any part of your life involves a non-Apple device, you have a problem:

• A Windows PC at work and a Mac at home
• An iPhone paired with a Chromebook or Android tablet
• A shared family computer that runs Windows
• A work laptop locked down by corporate IT (no App Store access)

“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

Things 3 users rarely say this. The app's simplicity is its accessibility.

What you gain by switching

To find a real alternative, you need to understand what Things users actually value. It's not just a feature list — it's a feeling.

“I have adult ADHD. I have owned OmniFocus 1, 2 and now 3 Pro, hoping it will help organize my life. And I have basically never used it.”Mac Power Users Forum

What Things 3 is missing

Things 3 is GTD-friendly, but it's not a full GTD implementation. If you follow the methodology strictly, you'll notice gaps:

• No sequential projects. Things has headings within projects and a “Next Action Steps” view filter, but it doesn't lock subsequent tasks. All tasks in a project are visible and completable at any time. For GTD, sequential unlocking is important — you should only see the next action, not the entire plan.
• No custom perspectives. Things provides fixed views: Today, Upcoming, Anytime, Someday. You can filter by tags, but you can't create saved custom views. OmniFocus-style perspectives that combine project, tag, date, and status filters don't exist.
• No weekly review mode. No guided review workflow. You manually go through each project. For a methodology where David Allen calls the weekly review “the critical success factor,” this is a meaningful gap.
• No API. Things has a URL scheme and Apple Shortcuts integration, but no REST API. You can't connect it to Zapier, n8n, or build custom integrations. Power users who automate their workflows are limited.

Things 3 vs SingleFocus

Here's how they compare directly — including where Things wins.

* Free plan ($0). Pro is $8/month or $72/year. First 30 paying customers lock in $36/year for life as founding members.

The design question: can a web app match Things?

The honest answer: no. Things 3's native Apple experience — the animations, the haptics, the Shortcuts integration — can't be fully replicated in a browser. That's the trade-off Cultured Code chose, and it's a valid one.

What SingleFocus does share with Things is a design philosophy: reduce cognitive load, show less, use gentle language, make the interface feel calm rather than busy. The warm off-white background, generous spacing, and intentional typography come from the same school of thought — your task manager should lower your stress level, not raise it.

The trade-off is clear: Things 3 gives you the most polished native experience on Apple. SingleFocus gives you a calm, structured GTD experience on any device. If you're fully Apple and don't need sequential projects, perspectives, or a review mode — Things 3 is a genuinely great choice. If you need any of those things, or need cross-platform access, SingleFocus fills the gap.

“Most people want a task management solution they can use anytime, anywhere. Unfortunately OmniFocus doesn't provide that unless you are using iOS or Mac devices.”Mike Vardy, Productivityist

The same applies to Things 3.
