The two most popular task managers, tested against the one question that matters: which one still works when your executive function is offline?
Things 3 if you're all-Apple. Visual calm, zero shame mechanics, one-time pricing.
Todoist if you use any non-Apple device. Natural language capture, works everywhere, free tier covers most needs.
Both are excellent task managers. The difference isn't features. It's how each one interacts with executive dysfunction, rejection sensitivity, and the ADHD tendency to abandon systems.
The interface has so little visual noise that there's almost nothing to decide. Open the app, look at Today, do the next thing. Projects use simple headings instead of nested complexity. The constraint is the feature: there aren't enough options to get lost in.
Quick add is frictionless, but the organizational system (projects, sections, labels, filters, priorities) creates a meta-task: organizing the organizer. ADHD brains can spend more time categorizing tasks than doing them. The fix: ignore most features and use only Inbox + Today. More on this in ADHD organization strategies.
Open it after a week away and it still looks calm. Overdue tasks don't scream at you with red indicators. The Evening section lets you park tasks you're not ready for without deleting them. The visual quiet makes it safe to return to.
Returning after time away means confronting a stack of overdue tasks marked in red. The Inbox may be full of unsorted items. For ADHD brains, this visual backlog can trigger overwhelm and avoidance of the tool itself. You can reschedule everything at once, but you have to know that feature exists.
No streaks. No scores. No "you completed 3 tasks today" notifications. No gamification at all. Tasks are just tasks. This lack of judgment is exactly what ADHD brains with rejection sensitivity need. The app never makes you feel like you're losing.
Karma tracks your productivity and shows a daily/weekly score. Streak counters reward consistency, which means breaking a streak feels like failure. You can turn Karma off in settings, but the default experience includes it, and most people never change defaults. Related: ADHD guilt and shame.
The app barely changes. No new features to explore every month. No redesigns to learn. This is boring in the way that ADHD brains secretly need: the tool becomes invisible, and you just use it. The dopamine hit comes from completing tasks, not from reconfiguring the system.
Regular feature updates and new integrations can trigger reorganization binges. Each update is an invitation to rebuild your system instead of using it. For ADHD brains that chase novelty, this is a productivity trap disguised as a feature. See: why ADHD systems stop working.
Apple-only means if you ever switch to Android or need a Windows machine for work, you lose your task manager completely. Your data stays trapped in the Apple ecosystem. This is the single biggest risk.
Works everywhere. Export is available. If you decide to switch to another tool, your data comes with you. No platform lock-in means the decision is always reversible.
Things 3 for Apple users. Todoist for everyone else.
If you're all-Apple, Things 3 is the better ADHD task manager. Its visual silence is a genuine competitive advantage for overstimulated brains. No other task app is this calm. The one-time pricing also removes the subscription guilt that makes ADHD brains avoid tools they're paying for but not using.
If you use any non-Apple device, the choice is made for you: Todoist. And it's a good choice. The natural language input is the fastest way to capture a thought before your brain moves on, which is the single most important feature for ADHD. Just turn off Karma, ignore the project sidebar, and use it as a simple Inbox + Today system.
The deeper truth: both are better than the system you're not using. If you've been keeping tasks in your head, in random notes, or in a text message to yourself, either of these is a massive upgrade. Pick the one that matches your devices and stop researching. The best task manager is the one you open tomorrow morning.
