Three Apps, Three Different Bets
The task manager market is not short of options in 2026. Todoist has crossed 40 million users. Things 3 consistently tops App Store productivity charts in its Apple-only lane. And a newer wave of privacy-first tools — Zero-Friction Tasks among them — is gaining ground as people grow wary of how much data their to-do list collects.
The real question is not which app has the longest feature list. It is which set of trade-offs fits how you actually work.
This comparison covers three specific categories that matter most in 2026: platform coverage, privacy model, and friction at the moment of capture.
Platform Coverage: Who Can Actually Use It?
Todoist
Todoist runs everywhere. Windows, macOS, Linux, iOS, Android, browser. If you use multiple platforms or switch devices regularly, Todoist is the most universal option available. Its cross-platform consistency has improved substantially — tasks sync within seconds even when you come back online after an offline period.
The cost of that universality: Todoist's free tier is genuinely limited. Collaborative features, filters, and reminders all sit behind the Pro plan at $4/month. If you are managing a complex project with tags, labels, and filters, you are paying.
Things 3
Things 3 is beautiful. That is not marketing language — the design genuinely is better than almost anything else in the category. The task entry UX, the natural deadline parsing, the area and project structure all feel considered.
But Things 3 only runs on Apple devices. iPhone, iPad, Mac, Apple Watch. That is it. If you have a Windows PC at work or a colleague who runs Android, Things 3 is invisible to them. The app costs a one-time fee ($9.99 iPhone, $19.99 iPad, $49.99 Mac) with no subscription — which many users prefer.
Zero-Friction Tasks
Zero-Friction Tasks targets the Windows + iPhone combination that falls between Todoist's everywhere approach and Things 3's Apple-only design. The app runs natively on both platforms — not a web wrapper on one side — and syncs via a private code with no cloud account required.
For someone who uses Windows at a desk and an iPhone everywhere else, this is the gap it fills directly.
Privacy Model: Where Does Your Data Actually Go?
This is where the three apps diverge most sharply.
Todoist
Todoist stores your tasks in the cloud, linked to your account. That means your task list — project names, deadlines, the things you are worried about, the things you are behind on — lives on Doist's servers, readable to their systems. Their privacy policy permits usage data collection for product improvement. If you care about what your task list reveals about you, that matters.
Things 3
Things 3 syncs via iCloud, which means your data lives in Apple's infrastructure. Apple has a strong privacy stance and end-to-end encryption for many iCloud features. For Apple ecosystem users, this is a meaningfully better position than a third-party cloud. But you are still handing data to a platform, even if it is one with better privacy practices than most.
Zero-Friction Tasks
Zero-Friction Tasks uses AES-256 end-to-end encryption with no account. There is no company database holding your tasks in plaintext. You generate a sync code, share it between your own devices, and your tasks never leave your control unencrypted. No profile is built from your usage. No server stores a readable copy of your task list.
This is not a privacy tier or an upgrade — it is the only mode the app operates in.
If your task list contains client work, personal health reminders, financial deadlines, or anything you would not want included in a data breach or regulatory request, the architecture difference is significant.
Capture Friction: The Moment That Actually Matters
The best task manager is the one you use at the exact moment you think of something. Everything else — design, features, integrations — is secondary to whether you can capture a thought in under five seconds without breaking what you were doing.
Todoist
Todoist has good quick-add shortcuts on most platforms. On desktop, a global shortcut opens an inline entry form. On mobile, the widget is reasonably fast. For most users, this is good enough.
Things 3
Things 3's Quick Entry on Mac is excellent — one keyboard shortcut, clean modal, done. On iPhone, the capture widget is fast. Within the Apple ecosystem, Things 3 may have the best keyboard-driven capture experience of any app.
Zero-Friction Tasks
On Windows, Alt+Space opens Zero-Friction Tasks as a floating capture window over whatever you are doing. No context switch, no login spinner, no navigating to an inbox. You press two keys, type, press Enter. Three seconds, maximum.
This matters more than it sounds. The reason most people's task lists degrade over time is not motivation — it is that they miss the capture moment. An idea comes up in the middle of an email and they think "I'll add that later." Later never comes. Alt+Space eliminates the excuse.
Head-to-Head: Feature Comparison
| Feature | Todoist | Things 3 | Zero-Friction Tasks |
|---|---|---|---|
| Platforms | All | Apple only | Windows + iPhone |
| Price | Free / $4/mo | One-time purchase | Free |
| Account required | Yes | Yes (Apple ID) | No |
| Encryption | In-transit | iCloud (E2E optional) | AES-256 E2E always |
| Quick capture | Global shortcut | Quick Entry (Mac) | Alt+Space (Windows) |
| API access | Yes (paid tier) | No | Yes (free, no OAuth) |
| Offline-first | Partial | Yes | Yes |
| Collaboration | Yes | No | No |
Who Should Use What
Todoist is the right call if you work across mixed platforms, collaborate with others on shared task lists, or need advanced filters and labels to manage complex project structures. Accept the cloud dependency and the subscription cost as the price of that flexibility.
Things 3 is the right call if you live entirely in the Apple ecosystem and value design above everything else. The one-time pricing is a genuine advantage for long-term users. You are trusting Apple's infrastructure, which is a reasonable bet.
Zero-Friction Tasks is the right call if you use Windows and iPhone, care about where your data goes, want to avoid creating another account, or need an API that works without OAuth overhead. The app is free, the sync is encrypted end-to-end, and Alt+Space on Windows is the fastest capture path of the three.
The Honest Summary
All three are good apps. The differences are architectural, not cosmetic.
Todoist chose universality and collaboration, and priced accordingly. Things 3 chose design and the Apple ecosystem, and charged a premium for it. Zero-Friction Tasks chose privacy and Windows+iPhone coverage, and made it free.
The right answer depends on which trade-off you can live without — a cloud account, Apple-only devices, or a paid subscription.
What none of them solve for you is the moment you think of something and do not write it down. That is the only task manager feature that actually matters.
