The to-do app question has a cleaner answer than most app categories, but the threads still don’t crown a single winner, and the reason is structural rather than about quality. In r/productivity the recommendation usually splits on two practical questions before anyone gets to features: what devices are you on, and do you want to buy it once or rent it forever. Answer those two and the field narrows to one app almost automatically. That’s why this is mixed-consensus — there’s a rough shape to the agreement, but it forks on facts about you, not on which app is better.
One caution worth front-loading, because it’s the thing the long-term threads keep circling: the productivity gain from a task app comes almost entirely from using it consistently, not from its feature set. People who bounce between apps every few months looking for the perfect one tend to get less done than people who picked a decent one and stuck with it. The honest framing of “best” here weights will you keep opening it far above the spec sheet.
The short version
| App | What it’s genuinely best at | Pricing shape | The complaint that keeps coming up |
|---|---|---|---|
| Todoist | Cross-platform reliability; fast natural-language capture | Free tier; Pro ~$5/mo | Free tier got tighter (project cap, reminders paywalled); feature-light vs rivals |
| Things 3 | Polish and calm design; one-time purchase | One-time (~$50 Mac, ~$10 iPhone, ~$20 iPad) | Apple-only; pay per device; no collaboration |
| TickTick | All-in-one: tasks + calendar + habits + Pomodoro | Free tier; premium ~$36/yr | Does a lot, so can feel busier; some features feel “good enough,” not best |
Todoist: the cross-platform default
Todoist is the reflexive recommendation when someone in r/productivity doesn’t specify their platform, because it runs well everywhere — Windows, Mac, Android, iOS, web, browser extensions — and syncs reliably across all of them. Its natural-language input (“submit report every Friday at 3pm”) is the fastest capture in the category, and the app has been stable and well-maintained for years, which matters more than novelty for something you’ll lean on daily.
The complaint that comes up most is the free tier tightening over time: it now caps you at a handful of personal projects and locks task reminders behind Pro, which annoyed long-time free users who remember a more generous plan. The other recurring note is that, feature-for-feature, it’s deliberately lean — no built-in calendar view or habit tracking like TickTick — which fans frame as focus and detractors frame as missing pieces.
Who it’s not for: people who want a calendar, habits, and timers in one app (TickTick does more), Apple-only users who’d rather pay once than subscribe (Things), and anyone who’ll resent reminders being a paid feature. If you need collaboration-heavy project management, this is a personal task app stretched thin, not a substitute for a real project tool.
Things 3: the calm, paid-once one
Things is the aesthetic and ergonomic favorite, and the r/productivity users who love it love it quietly and for years. The design is genuinely calming — there’s a deliberateness to how it handles Today, Upcoming, and Areas that makes planning feel less like a chore. And crucially, it’s a one-time purchase, which a large anti-subscription faction treats as the entire reason to choose it: buy it, own it, no recurring bill for a to-do list.
The caveats are specific and non-negotiable for some people. It’s Apple-only — no Windows, no Android, no web — so a single non-Apple device in your life rules it out. And the one-time purchase is per platform: the Mac, iPhone, and iPad apps are separate purchases, so “buy it once” can mean buying it three times, which the threads regularly grumble about even while still recommending it. There’s also no collaboration — it’s resolutely a personal app.
Who it’s not for: anyone outside the Apple ecosystem, anyone who needs shared lists or collaboration, and people who’d rather pay a small subscription than ~$80 across devices up front. It’s a beautiful single-player app and makes no apology for it.
TickTick: the one that does everything
TickTick is the pick for people who want their tasks, calendar, habit tracking, and a Pomodoro timer in one place instead of four apps. It’s cross-platform like Todoist, the natural-language input is comparable, and the recurring “TickTick does what Todoist charges for, plus more” comparisons are a fair summary of why people switch to it. For someone consolidating tools, the calendar view and built-in habits are a genuine draw.
The honest tradeoff is that doing more means being more — the interface carries more, and people who want a minimalist task list sometimes find it busier than they’d like. And while each feature is solid, none is necessarily best-in-class: the calendar isn’t a Fantastical replacement, the habit tracker isn’t a dedicated habit app. It’s the strong all-rounder, which is exactly the right call for some people and the wrong one for purists.
Who it’s not for: minimalists who want only a clean task list (Things or lean Todoist), people who already have dedicated calendar and habit apps they like, and anyone who finds feature-dense apps distracting. The all-in-one breadth is the value and the cost in the same breath.
Where the room is split
The disagreement is practical, not ideological, and it resolves on two questions:
- On multiple platforms and fine with a light subscription? Todoist.
- All-Apple and prefer to pay once? Things 3.
- Want tasks plus calendar plus habits in one app? TickTick.
There’s also the perennial, reasonable minority that points out a plain text file, Apple Reminders, or a paper list is enough for a lot of people — and for anyone who keeps abandoning apps, the free built-in option you’ll actually use beats the paid one you won’t. We’re not going to pretend everyone needs a dedicated app.
So what should you actually use?
- Cross-platform, fast capture, don’t mind ~$5/mo? Todoist.
- Apple-only and want to buy it once with the nicest design? Things 3.
- Want one app for tasks, calendar, and habits? TickTick.
- Already get by with Reminders or a notebook? Stay there; consistency beats features.
That’s not a coronation, and the category doesn’t really need one — all three are good, and the right answer falls out of your platforms and your feelings about subscriptions. The one thing the long-term threads agree on is the uncomfortable part: the app you keep opening in month six beats the one with the better feature list you quit in week two.
