The best Windows to-do list app depends on the system that should own your work. Choose Microsoft To Do when Outlook, Microsoft accounts, and Planner are central; Todoist for structured projects across devices; SingularityApp for tasks, habits, and planning in one workspace; TickTick for reminders and calendar features; Workflowy for nested outlines; or Super Productivity for local-first, open-source use.
There is no universal winner. Compare the task model, collaboration needs, calendar features, offline behavior, account requirements, Windows experience, and the limits of the plan you will actually use. Windows availability does not mean an app is preinstalled, nor does it mean every feature works identically on every platform. Prices and plan limits in this guide were checked November 14, 2026. Country, tax, billing cycle, app store, and purchase channel can change the amount.
Use this guide to shortlist two apps, then test one with representative sample tasks before migrating real work. The goal is not to find the longest feature list. It is to find a task system that people can capture, find, update, and complete without creating a second, conflicting record elsewhere.
How to choose a Windows to-do list app
Start by identifying which system owns active tasks today: Microsoft 365, a standalone task manager, an outline, or a local-first tool. Then name the one missing capability that would justify moving. If an app cannot provide that capability on the plan and devices you will use, remove it from consideration.
- Task structure: Do you need projects, sections, labels, owners, priorities, and due dates, or is a flexible outline enough?
- Collaboration: Will other people share lists, receive assignments, or work in a team space?
- Calendar and reminders: Do you need tasks beside calendar events, task duration, recurring reminders, or a full calendar view? Check the plan for the exact feature.
- Accounts and sync: Does the app require a Microsoft account, a paid plan, Exchange Online, or a manually configured sync provider?
- Windows use: Test installation, sign-in, keyboard entry, notifications, and offline behavior on the actual PC. Confirm that the other devices you rely on can access the same tasks.
- Free-plan limits: Compare the constraint that could affect your workload: project count, monthly nodes, tasks per list, reminder capacity, calendar tools, or account licensing.
Choose one system to own each active task. Connecting multiple lists without an ownership rule creates parallel records that can disagree about the due date, status, or person responsible.
Compare six Windows task apps by fit and free-plan limits
This table is for shortlisting, not for declaring a universal winner. Open the official plan page before purchase or rollout because limits and prices change.
| App | Best fit | Free-plan reality | Main tradeoff |
|---|---|---|---|
| Microsoft To Do | Microsoft accounts, Outlook, and Planner workflows | Free; work or school synchronization requires an enabled To Do license and Exchange Online | Most useful when Microsoft services already own the work |
| Todoist | Structured projects and cross-device task management | Beginner supports up to five personal projects; Pro supports up to 300 personal projects | Some calendar, reminder, reporting, and task features are paid |
| SingularityApp | Tasks, habits, and planning in one workspace | Basic allows 10 projects, five sections per project, and three habits | Connected-calendar viewing is different from the Pro calendar view and Google Calendar integration |
| TickTick | Reminders, habits, and task planning | Free includes nine lists, 99 tasks per list, synchronization, and task reminders | Premium adds capacity and features such as multiple calendar views |
| Workflowy | Nested bullets and outline-based thinking | Basic allows 100 nodes per month | Bullets are not the same data model as structured task records |
| Super Productivity | Offline, local-first, open-source task management | Free; the vendor lists no premium tier | Optional synchronization must be configured rather than assumed |
Current listed prices also differ. SingularityApp Pro is listed at $3.33 per month billed annually or $3.99 billed monthly. TickTick Premium is listed at US$49.99 per year. Workflowy Pro is listed at $6.99 per month billed annually or $8.99 billed monthly. Todoist pricing depends on billing cycle and region. Check the official plan pages for the amount and terms that apply to your account.
The best app for each Windows task workflow
Microsoft To Do: Outlook, Microsoft accounts, and Planner
Choose Microsoft To Do when Microsoft services already form the operating system for your work. My Day supports daily planning, and tasks assigned to you in Planner can appear in To Do’s Assigned to me list when the relevant account and licensing conditions are met. Microsoft documents To Do as available for Windows 10 and newer. That does not establish that it is installed on every Windows 11 PC.
For work or school accounts, Microsoft documents an enabled To Do license and an Exchange Online mailbox as requirements for synchronization and storage. To Do also includes features such as due dates, reminders, repeating tasks, steps, notes, files, and list sharing, although some documented features are presented through Outlook or Outlook on the web. Review Microsoft’s setup and account requirements and its guidance on Planner tasks in To Do.
Todoist: structured tasks and projects across devices
Choose Todoist when projects, sections, labels, filters, priorities, due dates, and parent tasks matter across your devices. Its free Beginner plan is limited to five personal projects; Pro supports up to 300 personal projects. Todoist lists calendar layout, task duration, custom reminders, expanded filters, reporting history, Task Assist, and deadlines among current Pro features.
Do not use an individual-plan project limit to infer team or guest limits. Team workspace capabilities are a separate question and should be checked on the current Todoist pricing page. Todoist’s billing FAQ also explains why displayed prices can vary by billing cycle and region.
SingularityApp: a planning workspace beyond task lists
Choose SingularityApp if you want tasks and projects alongside habits and other planning tools. Basic allows 10 projects, five sections per project, and three habits. Pro is currently listed at $3.33 per month with annual billing or $3.99 with monthly billing. The page also lists an Elite tier, so do not treat Pro as the only paid option.
One calendar distinction matters: Basic lists connected web-calendar viewing, while the full calendar view and Google Calendar integration are listed under Pro. SingularityApp also documents a printable day-plan workflow and imports from several task systems. The knowledge base confirms that documentation exists, but test a small sample before assuming that every field will migrate. Use the official plan comparison and knowledge base for current details.
TickTick: reminders, habits, and calendar planning
Choose TickTick when reminders and personal planning features are central. Free includes task reminders, cross-platform synchronization, up to nine lists, and up to 99 tasks per list. It also lists natural-language processing and list or Kanban views. Premium expands capacity and includes features such as multiple calendar views, task duration, email reminders, themes, and higher limits for several record types.
The reviewed official page lists TickTick Premium at US$49.99 per year. Free is not a reminder-free plan, but it may not provide the capacity or calendar features your workflow needs. Compare the current TickTick plan details against actual usage before deciding.
Workflowy: outline first, task fields second
Choose Workflowy if you naturally plan in nested bullets and want a flexible outline canvas. Basic allows 100 nodes per month, while Pro is listed at $6.99 per month billed annually or $8.99 billed monthly. Pro also lists unlimited nodes and uploads.
A bullet can capture an action in its place in an outline, but it is not equivalent to a structured task with dedicated fields for assignee, priority, and due date. If those fields drive your process, test Todoist or Microsoft To Do instead. The product name is Workflowy, not Workflow or Workflowly.
Super Productivity: local-first and user-configured sync
Choose Super Productivity when offline use, open-source licensing, time tracking, and control over synchronization are priorities. The vendor describes the app as MIT-licensed, free, available for Windows and other platforms, and usable offline. Tasks, timers, and notes run locally; optional synchronization uses a provider you configure.
The official integration documentation says synchronization runs while the app is open and notes that plugins are not strongly sandboxed. Treat those as vendor-documented characteristics, not an independent privacy or security audit. Review each provider’s permissions and install only plugins you trust. See the download and product information and integration documentation.
Microsoft To Do or Todoist
Use lists and task fields when projects, dates, priorities, assignments, or Microsoft service ownership determine what happens next. Avoid this model if you mainly want an unrestricted space for developing ideas.
Workflowy
Use nested bullets when hierarchy and freeform thinking are the primary organizing tools. Choose a structured task app if assignment, priority, and due-date fields must be filtered or managed independently.
Test the app on your Windows workflow before migrating
Run a short trial with representative, non-sensitive sample tasks. Capture one, add a date, organize it, find it again, then complete or reschedule it. Repeat on the Windows PC and another device you use. Check installation, sign-in, keyboard entry, notifications, and offline behavior rather than judging from a feature list.
Before migrating, list the fields you rely on: due dates, labels, hierarchy, attachments, completion state, and history. Move or re-enter a small sample and verify each field in the destination. Import documentation does not by itself guarantee that every field transfers. Keep the old system read-only until the sample passes and a named owner can resolve mismatches.
Test the task fields that drive decisions, not just whether a title appears. A migration that preserves names but loses dates, hierarchy, ownership, or completion history may create more work than it removes.
When a task should be created automatically
Automation is useful when another app produces a clear task event and a person should not have to retype it. Use deterministic rules first: route an item already marked as a task, and preserve a date that the source explicitly states. Use AI only when text needs summarizing, classifying, or extracting. Treat proposed dates, owners, and task divisions as unconfirmed when the source is unclear or sensitive.
Zapier documents supported triggers and actions for these products, but its integration pages are not automatically complete, tested templates. Microsoft To Do triggers are polling-based, and the displayed Todoist and TickTick integrations can also introduce polling delay. A lookup followed by creation is not atomic under concurrent runs. For high-concurrency workflows, enforce uniqueness in an external datastore with a database unique key and transactional upsert, or use a destination operation with documented idempotency.
| Destination | Trigger and AI job | Validation | Action and fallback |
|---|---|---|---|
| Microsoft To Do | Supported external event, such as a message explicitly marked as a task. No AI when the title and date are already clear. | Require a non-empty title, validate date and timezone, select an existing list, and check account access. | Use the documented Create Task or Find or Create Task action. The list owner resolves permissions, missing dates, and existing-task conflicts. |
| Todoist | Supported message or form event. AI may propose a concise task from ambiguous text, but must not invent a deadline or assignee. | Validate the project, title, structured fields, confidence threshold, and human approval for unclear or sensitive content. | Create a task with only applicable fields such as project, section, note, priority, labels, parent task, and due date. Send unresolved proposals to the project owner. |
| Workflowy | Explicit external action. Optional AI may shorten or summarize the text without turning uncertain language into a commitment. | Confirm the Save Location URL and include a stable source identifier in the note or external log. | Use the documented Create Bullet action. Move or remove a misplaced bullet, or use a structured task manager when fields are required. |
| TickTick | Supported external note or event. Map an explicit title, content, date, and priority; use AI only for bounded extraction. | Validate the destination list, date, timezone, capacity, and source identifier. Confirm Premium requirements for features the workflow depends on. | Use the documented Add Task action. Preserve the source URL in task content and route invalid dates or duplicate keys to an operator. |
For every destination, key the record by source system, source account, source event ID, destination system, and destination account. If one event produces several tasks, add an extracted-task identifier or ordinal. Do not deduplicate on title, date, project, or the day the automation runs.
- Microsoft To Do: Zapier documents Create List, Create Task, Complete Task, Find a Task, Find or Create Task, and an API Request action. The exact source trigger and optional field availability depend on the connected application and Zap configuration. Preserve the source event ID in notes or an external log, and expect polling rather than real-time processing. See Zapier’s Microsoft To Do documentation.
- Todoist: The documented action can map project, title, note, section, assignee, due date, deadline date, priority, labels, and parent task where applicable. A human should approve an AI proposal when the owner or date is ambiguous. A stable source event ID plus extracted-task identifier prevents unrelated tasks from sharing a duplicate key. See Zapier’s Todoist integration documentation.
- Workflowy: The verified action creates a bullet with Save Location URL, Title, and Note. It does not establish a general trigger for new or changed Workflowy bullets. Check the destination node before writing, and send requests requiring assignees or structured due dates to a task manager instead. See Zapier’s Workflowy integration listing.
These are proposed implementation designs built from documented connector capabilities, not claims of ready-made end-to-end workflows. Test the source trigger, field mapping, polling interval, permissions, and failure path in a non-production workspace before enabling writes. For help designing bounded task automation, see Zapier automation services or, where extraction requires review and controlled writes, AI agent services.
A practical adoption decision
Pilot one app for a week with one task owner, one primary list or project, and a limited set of workflows. Measure whether tasks are captured and found, how many go overdue, whether duplicate records appear, whether sync fails, and how much time people spend maintaining the tool. These are rollout measures, not guaranteed product outcomes.
- Did a sample task retain every field your work depends on?
- Do sign-in, permissions, and synchronization work on the actual Windows PC and account?
- Is there one named system of record and an owner for active tasks?
- Does someone own failed imports, unclear AI proposals, and duplicate conflicts?
- Can you keep the old system read-only until the pilot passes?
Keep the pilot if capture and retrieval improve without unresolved duplicates or synchronization failures. Otherwise, remove the automation or choose a better-fitting app before moving the full backlog. Microsoft To Do fits Microsoft-centered work, Todoist fits structured projects, SingularityApp fits an all-in-one planning workspace, TickTick fits reminder-heavy planning, Workflowy fits outline thinking, and Super Productivity fits local-first control. The right choice is the one whose task model and account requirements match the work you need to manage.
