Software for Getting Things Done: 9 Tools Compared (2026)
Fabio Bergmann
Software for getting things done is any task manager that helps you reliably capture, organize, and complete work, often built around David Allen's GTD method or a simpler task, project, and habit workflow for people who just want friction-free daily execution.
Key takeaways
- Things 3 costs 50% less upfront than OmniFocus's yearly subscription ($49.99 one-time vs $99.99/year), so check the math before assuming subscriptions win long-term.
- GTD is a five-step method (capture, clarify, organize, reflect, engage); the app matters less than whether your system supports all five consistently.
- Superlist Basic ($5/mo) and Todoist Pro billed yearly ($5/mo) cost the same but package very different features. Price parity isn't feature parity.
- TickTick's annual premium at $35.99 runs $23.99 cheaper than Todoist Pro's $60 yearly plan.
- Notion and Obsidian can approximate a GTD system with manual setup, but purpose-built apps handle contexts, next actions, and reviews with far less configuration.
What Is Software for Getting Things Done?
Software for getting things done is any task manager that helps you capture, organize, and complete work reliably. Most tools build on David Allen's GTD method, defined as capture, clarify, organize, reflect, and engage, or offer a lighter task, project, and habit workflow for friction-free daily execution.
There are two camps. GTD-specific apps like OmniFocus and Things 3 implement Allen's structure directly, with projects, contexts, and review cycles. General task managers built for speed, like Todoist and Dooit, favor fast capture and quick execution over strict methodology.
The core problem is the same for most people: a slow, cluttered tool breaks trust in the system. When capture takes three taps and the app hangs on load, you stop capturing, and the whole method collapses. Whether "best" means full GTD rigor or lightweight daily execution depends on your habits.
How Do You Set Up a Trusted Digital GTD System?
A trusted digital GTD system needs one inbox for capture, a clarify step that assigns next actions and projects, weekly reviews to refresh contents, and quick engage-time filtering by context or priority. Most guides list these steps but skip the concrete sequence below.
Capture everything in one place
Pick one inbox app and funnel every task, idea, and commitment into it immediately. GTD's Capture step means collecting anything that has your attention into a collection tool. Two inboxes means two systems, and two systems means no system.
Clarify into next actions
For each inbox item, decide whether it's actionable. GTD's Clarify step is about deciding the next action and project if the answer is yes. "Plan the offsite" is not a next action. "Email Sara to book the venue" is. Write the physical action.
Build your review cadence
Schedule a fixed weekly slot to update and re-scan the whole system, not just today's list. As David Allen's team puts it, the Reflect step exists to:
update and review all pertinent system contents to regain control and focus. [GTD]
Organize clarified items into projects, contexts, or tags so engage-time filtering is instant, then use today, context, or project views to pick your next action without re-deciding priorities mid-day.
Do Notion or Obsidian Work Well as a GTD System?
Notion and Obsidian can run a GTD system through databases, linked notes, and templates, but both require manual setup for contexts, next-action views, and review checklists that purpose-built apps provide out of the box. That's a real tradeoff most ranking pages skip for keyboard-first users.
- Notion: databases can model projects, contexts, and next actions, but filtering speed depends on manual view configuration, and mobile capture is slower than a dedicated inbox app.
- Obsidian: plugins like Tasks and Dataview approximate GTD contexts and reviews, but there's no built-in weekly-review perspective. You build your own and maintain it.
- Both suit people who already live in notes-based tools and don't mind assembling their own GTD scaffolding.
Keyboard-first users often find Obsidian's command palette closer to a real GTD workflow than Notion's mouse-heavy UI. The honest cost of either: you spend setup time replicating the clarify and reflect steps that OmniFocus ships by default across its seven standard perspectives.
Software for Getting Things Done: Comparison Table
Pricing, platforms, and GTD-specific mechanics vary widely across task managers, from Things 3's one-time Mac purchase to OmniFocus's perspective-based review system to Dooit's flat $9/month plan. The right fit depends on whether you prioritize GTD structure, price, or raw speed.
| App | Price | Platforms | GTD mechanic | Best for |
|---|---|---|---|---|
| Todoist | Free (5 projects) / Pro $5/mo yearly | Cross-platform + web | Labels + 150 filter views | Flexible free-tier basics |
| Things 3 | $49.99 Mac / $9.99 iPhone / $19.99 iPad (one-time) | Apple only | Projects + areas | One-time purchase on Apple |

Todoist: Best for Flexible Free-Tier GTD Basics
Screenshot: Todoist help page, July 2026.
Todoist pairs a genuinely usable free plan with a Pro tier at $5/month billed yearly that unlocks 300 projects and 150 filter views. It's a low-cost entry point for GTD-style project and context organization through labels and filters.
The free plan covers casual setups with 5 personal projects, 3 filter views, and 1 week of activity history — meaning Pro's jump from 5 to 300 projects is a 60x increase, and 3 to 150 filter views a 50x jump, if you actually hit those ceilings. Pro's 150 filter views can emulate GTD contexts like @calls and @errands at scale. Todoist Business at $8/mo yearly adds team features most solo GTD users won't need. The main gap: no native weekly-review perspective, so you build review filters by hand.
Things 3: Best for One-Time Purchase on Apple Devices
Screenshot: Things 3 things page, July 2026.
Things 3 is a one-time purchase, priced at $49.99 Mac, $9.99 iPhone, and $19.99 iPad, with free Things Cloud sync and no subscription. That $49.99 Mac price is 50% lower upfront than OmniFocus's $99.99/year plan, though Things is Apple-only, so Windows, Android, and Linux users are excluded.
Things is sold as a one-time purchase, not a subscription, and syncs free. It runs on Mac, iPhone, iPad, Apple Watch, and Vision Pro, but not Windows, Android, Linux, or web. A 15-day free trial on Mac with full feature access lets you test the whole project and area structure before buying. If you're deciding between the two, our Todoist vs Things 3 breakdown goes deeper.
TickTick: Best for Cross-Platform Coverage at Low Cost

TickTick covers the widest platform range of any app here, spanning iOS, Android, Windows, macOS, Linux, a browser extension, and web, at $35.99/year premium. That comes in $23.99 cheaper than Todoist Pro's $60 yearly plan while adding a full calendar, checklist reminders, and habit-adjacent stats.
TickTick runs on iOS, Android, Windows, macOS, Linux, and web, including Linux, which most rivals skip. Premium unlocks a full calendar, customizable filters, historical statistics, checklist-item reminders, calendar widgets, and premium themes useful for the reflect step. On price, TickTick's $35.99/year, down from $49.99, lands $23.99 under Todoist Pro's $60 yearly equivalent. The limitation: no dedicated GTD perspectives or context system, so organization leans on tags and lists.
OmniFocus: Best for Full GTD Contexts and Perspectives
OmniFocus is the closest thing here to a purpose-built GTD engine, with seven standard perspectives covering Inbox, Projects, Tags, and a dedicated Review view for recurring review cycles. Pricing runs from $74.99 one-time up to $99.99/year including web access.
The seven perspectives map onto capture, organize, and reflect, and the Review perspective is built to keep regular project review current without manual filter-building. Pricing spans a $74.99 Standard license, a $149.99 Pro license, and a $99.99/year subscription with web access; there's also a standalone $4.99/month web-access tier. The tradeoff is a steeper learning curve and higher cost than most alternatives here.
Superlist: Best for Shared Lists and Lightweight AI Features
Screenshot: Superlist pricing page, July 2026.
Superlist's free tier covers 5 private and 5 shared lists with unlimited tasks, while Basic at $5/month matches Todoist Pro's yearly price but swaps project-count limits for Voice AI and integrations. It's a different value trade aimed at collaborative, GTD-adjacent workflows.
The free tier includes 5 private lists, 5 shared lists, 25 MB file uploads, 500 MB total storage, and macOS/iOS/Android/web access. Basic at $5 per person/month, or $59 yearly, bundles unlimited lists, integrations, and Voice AI. Super at $21/month, or $249 yearly, adds AI meeting notes and Slack/email summarization — that's a 4.2x jump over Basic's monthly rate, more than most solo GTD practitioners need. The gap for GTD purists: no dedicated context or perspective system.
Dooit: Best for Keyboard-First Speed Over Full GTD Structure
Screenshot: Dooit website, July 2026.
Dooit is a minimal, keyboard-first task manager built for every action to complete in under 50ms. It combines Kanban and list toggling, natural-language scheduling, and week-to-multi-year goal tracking with daily habit streaks, for $9/month flat with no tiers.
Dooit's sub-50ms actions run with no spinners, no loading, no lag — as fast as you can think, which suits people frustrated by sluggish GTD apps. A single keystroke switches Kanban and list views, and 20+ keyboard shortcuts with full undo and redo speed up capture-and-clarify cycles. Natural-language dates like "tomorrow," "next Friday," and "every Monday" cut friction during the clarify step.
Goal tracking spans week, month, year, and multi-year horizons alongside daily habit streaks, which is broader than a typical GTD next-action list. Everything syncs in real time across desktop and a dedicated mobile app. The honest limitation: Dooit has no built-in GTD perspectives or context tagging like OmniFocus, so it fits fast daily execution better than strict GTD ritual. One plan with everything: a single $9/month with a 7-day free trial, no tiers, no add-ons, no surprises.
What's the Best App for GTD, ADHD Focus, and Specific-Task Software?
There's no single best app. OmniFocus suits strict GTD practitioners who want perspectives and reviews built in. Things 3 suits Apple users wanting a one-time cost. ADHD-friendly picks favor low-friction capture and instant feedback. Task-specific software depends on whether you need contexts, calendars, or collaboration.
- Full GTD methodology: OmniFocus (perspectives) and Things 3 (one-time purchase, projects and areas) most directly implement Allen's structure.
- ADHD-friendly traits: minimal steps to capture, instant visual feedback, and no loading delays favor fast, low-friction tools over feature-dense ones.
- Specific tasks: calendar-heavy work favors TickTick's full calendar and widgets; team and shared tasks favor Superlist's shared lists; solo speed favors Dooit.
The decision hinges on your actual workflow, not an objectively "best" app. The deciding factor is which tradeoff, structure versus speed versus platform, matches your habits. For a wider view, our guide to the best task management software for individuals compares more options.
Frequently asked questions
What is the best app for Getting Things Done?
There's no universal best app. OmniFocus offers the most complete GTD structure with built-in perspectives and review cycles, while Things 3 suits Apple users wanting a one-time purchase. Lighter tools like Dooit or Todoist work for people who want GTD-inspired capture and next-action habits without full methodology overhead.
What software helps with specific tasks like scheduling or habit tracking?
For calendar-heavy scheduling, TickTick bundles a full calendar and reminders. For habit tracking alongside tasks, Dooit combines daily streaks with goal tracking across week, month, year, and multi-year horizons. For team task sharing, Superlist's shared lists and integrations fit better than single-user GTD apps.
What is a good task app for ADHD-related focus challenges?
Apps with minimal friction tend to help most: fast capture, instant feedback, and few required decisions per task. Dooit's sub-50ms actions and natural-language scheduling reduce the steps between thought and captured task, while TickTick's habit and calendar widgets add visual structure some ADHD users find grounding.
Do any apps implement the full GTD methodology by David Allen?
OmniFocus most closely implements full GTD, with perspectives for Inbox, Projects, Tags, and a dedicated Review view built around capture, clarify, organize, and reflect. Things 3 supports GTD-style projects and areas well too, though neither app is officially licensed or endorsed by the GTD organization itself.
Can Notion or Obsidian replace a dedicated GTD app?
Yes, with manual setup: both can model projects, contexts, and next actions through databases or linked notes and plugins. Neither includes a built-in weekly-review perspective or context filtering the way OmniFocus does, so you'll spend more setup time building the scaffolding purpose-built GTD apps provide by default.
How do software tools support GTD weekly reviews?
OmniFocus has a dedicated Review perspective that resurfaces projects needing attention on a set cadence. Other apps like Todoist or TickTick require building manual filters or recurring tasks to replicate a weekly review, since reflect-stage support varies widely across mainstream task managers.
Want fast capture without the setup overhead? Start free with Dooit and see if sub-50ms, keyboard-first execution fits your day.
