To-do apps help organize personal and professional tasks. The right app depends on: complexity needs, ecosystem preference, and specific workflow methodologies (GTD, etc.).
| Use Case | Best Pick | Cost |
|---|---|---|
| Best Overall | Todoist | $5/month |
| Best for Apple Users | Things 3 | $9.99 (one-time per platform) |
| Best All-in-One | TickTick | $35.99/year |
| Best Free | Microsoft To Do or Apple Reminders | $0 |
| Best for GTD | Todoist | $5/month |
| Best for Habits | Streaks (iOS) or Loop (Android) | $5-10 |
Todoist is the most-recommended general-purpose to-do app. Natural language input, cross-platform (everything), reminders, recurring tasks, projects, labels, filters.
Why "best overall": Polished across all platforms. Doesn't lock you into ecosystem. 15+ years of refinement. Active development. Best for GTD methodology.
Pricing (2026):
Key features:
Compromise: Subscription required for advanced features. Mobile experience slightly less polished than Things 3. Team features less robust than ClickUp/Asana.
Things 3 is the premium to-do app for Apple ecosystem. Beautiful design, fast performance, GTD-compatible methodology, no subscription.
Why "best for Apple users": For Mac/iPhone/iPad users wanting polished experience without subscription, Things 3 is the standard. One-time purchase per platform.
Pricing (2026):
Total for full ecosystem: $79.98 one-time. Cheaper long-term than Todoist subscription ($60/year = $300 over 5 years).
Key features:
Compromise: Apple-only (no Windows, Linux, web). One-time cost per platform ($80 total). No team collaboration. Limited natural language (good but not as powerful as Todoist).
TickTick combines to-do, calendar, and habit tracking in one app. Cross-platform, robust feature set, affordable subscription.
Why "all-in-one": For users wanting one app for tasks + calendar + habits, TickTick provides this without the learning curve of ClickUp.
Pricing (2026):
Features (Premium):
Key advantage: At $35.99/year (roughly $3/month), TickTick is cheaper than Todoist ($60/year) while including calendar + habits. No need for separate calendar app.
Compromise: Less specialized than dedicated apps for each function (TickTick tasks < Todoist's power, TickTick calendar < Fantastical's UX). UX less polished than Things 3. Learning curve steeper than Apple Reminders.
Microsoft To Do (free): Cross-platform, Microsoft 365 integration, "My Day" focus view.
Apple Reminders (free): Native Apple, Siri integration, location reminders, family sharing.
Both are genuinely capable for most personal task management needs.
GTD (Getting Things Done by David Allen) is a popular task management methodology. Todoist's structure aligns well with GTD principles.
GTD support in Todoist:
Other GTD-friendly apps: Things 3, OmniFocus (premium GTD app for Mac/iOS).
For habit-building specifically (not task management), dedicated habit apps work better.
Streaks (iOS): $4.99 one-time, beautiful design, tracks up to 12 habits.
Loop (Android, free): Open source, comprehensive features, free.
For users specifically focusing on building habits (exercise, meditation, reading): dedicated habit app provides better experience than general to-do app.
Examples:
Best NLP: Todoist, Things 3.
| App | iOS | Android | Mac | Windows | Web |
|---|---|---|---|---|---|
| Todoist | ✓ | ✓ | ✓ | ✓ | ✓ |
| Things 3 | ✓ | ✗ | ✓ | ✗ | ✗ |
| TickTick | ✓ | ✓ | ✓ | ✓ | ✓ |
| Microsoft To Do | ✓ | ✓ | ✓ | ✓ |
For cross-platform users: Todoist or TickTick.
For Apple-only users: Things 3 or Apple Reminders.
All major apps support recurring tasks, but flexibility varies:
For shared tasks/projects:
For team task management: dedicated project management tool (Asana, ClickUp) often better than to-do app collaboration.
Premium tiers typically unlock advanced integrations.
David Allen's methodology:
1. Capture: All ideas/tasks into inbox
2. Clarify: What is it? Is it actionable?
3. Organize: Right list (someday, waiting for, contexts)
4. Reflect: Weekly review
5. Engage: Take action
Best app: Todoist (most users) or OmniFocus (power users).
Categorize by urgency/importance:
Best app: Tools with custom filters (Todoist).
Schedule tasks into calendar slots:
Best app: TickTick (calendar integration) or Things 3 + calendar.
Daily log of: tasks, events, notes. Migration of unfinished tasks.
Digital equivalents: Notion (templates available), Apple Notes, custom systems.
The biggest barrier: getting tasks into the system. Easy capture (Siri, widgets, quick add) makes this happen.
Tasks without reminders get forgotten. Strong reminder systems are essential.
Finding "all errands" or "everything due this week" requires good filtering.
Capturing on phone, viewing on desktop, completing anywhere — all require reliable sync.
Apps you enjoy using = used more. Slow or ugly apps get abandoned.
| App | Monthly | Annual | Best For | Platform |
|---|---|---|---|---|
| Todoist Pro | $5/mo | $60/year | GTD power users | All |
| Things 3 | N/A | $80 one-time | Apple users | Mac/iOS/Watch |
| TickTick Premium | $2.99/mo | $35.99/year | All-in-one (tasks+calendar) | All |
| Microsoft To Do | Free | Free | Microsoft ecosystem | All |
| Apple Reminders |
5-year cost comparison (single user):
1. Overcomplicating early: Too many projects, labels, custom fields from day 1. Start simple. Add structure as you need it.
2. No regular review: Tasks pile up; system breaks down. Weekly review essential (GTD principle). Spend 30min on Sunday reviewing/organizing.
3. Multiple apps simultaneously: Each captures different things. Standardize on one. Using Todoist + Things 3 + Apple Reminders = duplicate capture, ignored lists.
4. Treating to-do app as everything: Better to use specialized tools for: calendar, notes, project management. To-do app focused on tasks. Don't dump "brainstorm ideas" in tasks.
5. No habit of capturing: Best to-do app fails if you don't capture tasks. Form the habit first. Spend one week capturing everything before evaluating apps.
6. Confusing to-do app with calendar: Tasks are "what I need to do"; calendar is "when I'll do it". Use both: capture in to-do app, schedule on calendar when committing time.
