To-do lists don't need to be complicated—plenty of people use a pen and paper for the job without any problem. And yet a new to-do list app seems to come out every day. Why? Because keeping track of your tasks is an intensely personal thing, and people will reject anything that doesn't feel right pretty much instantly. That makes it hard to find the right app.
To that end, we've been hard at work researching the best to-do apps, trying to find the right ones for various use cases. Research for these pieces was exhaustive. We started by finding the best apps for every platform: Android, Windows, macOS, and iPhone/iPad. We then tried the top-rated apps in every respective app store, and spent way too much time migrating our personal to-do lists from one app to another.
And now we're offering you what we feel is the cream of the crop. Whatever you're looking for, one of these apps is going to be right for you. Click on any app to learn more about why we chose it, or keep reading for more context on to-do list apps.

What makes a great to-do list app?
When it comes to to-do lists, everyone has different criteria. We kept this in mind as we tested apps and noticed a few features that made certain ones out.
The best to-do list apps:
Make it fast to add and organize tasks. Ideally, a task is added and categorized in a couple taps or keystrokes.
Offer multiple ways to organize your tasks. Tags, lists, projects, and due dates are all helpful, and the best apps offer at least a few categories like this.
Remind you about self-imposed deadlines. Notifications, widgets, emails—the best applications make it obvious when something needs to be completed.
Offer clean user interfaces. Well-designed to-do apps fit into your workflow so you can get back to what you're supposed to be doing.
Sync between every platform you use. Which platforms will depend on what you personally use, but we didn't consider anything that doesn't sync between desktop and mobile.
We tried to find the best apps that balance these things in various ways. None of these options will be right for everyone, but hopefully one of them is right for you. Let's dive in.
Best to-do list app for balancing power and simplicity
Todoist (Windows, macOS, Android, iPhone, iPad, Web)
Todoist isn't the most powerful to-do list out there. It's also not the simplest. That's kind of the point: this app balances power with simplicity, and it does so while running on basically every platform that exists. That's a strong selling point—which is probably why Todoist is one of the most popular to-do lists right now, with over 10 million users.
Adding tasks was quick on every platform in our tests, thanks in part to natural language processing (type "buy milk Monday" and the task "buy milk" will be added with the next Monday set as your due date). You can put new tasks in your Inbox and then move them to relevant projects; you can also set due dates. Paid users can create custom filters and labels, and there are also some basic collaboration features.
Todoist is flexible enough to adapt to most workflows but not so complicated as to overwhelm. Overall, this is a great first to-do list app to try out, especially if you don't know where to start.
Todoist integrates with Zapier, which means you can automatically create tasks in Todoist whenever something happens in one of your favorite apps. Here are some examples.
Todoist price: Free version available; paid version from $3/month

Best to-do list app with embedded calendars and timers
TickTick (Android, Windows, macOS, iPhone and iPad, Web)
TickTick is a fast-growing to-do list app that offers a wide array of features on just about every platform you can imagine. Adding tasks is quick thanks to natural language processing. There's also a universal keyboard shortcut offered on the desktop versions and pinned notifications and widgets on mobile, which makes it quick to add a task before getting back to what you're doing. Tasks can be organized using lists, tags, and due dates, and there's even the ability to add sub-tasks to any task.
TickTick offers all of this with apps that feel native—the macOS version is distinct from the Windows version, for example, in ways that make sense given the differences between those two systems. TickTick also offers a few features that are above and beyond what other apps offer. First of all, there's a built-in Pomodoro timer, allowing you to start a 25-minute work session for any of your tasks. Second, there's integration with various third-party calendars, allowing you to see your tasks and your appointments in one place, and even do some time blocking. There's also a built-in habit-tracking tool, allowing you to review how many days you did or didn't stick to your exercise and diet commitments. It's a great collection of features, unlike anything else on the market.
With TickTick's Zapier integration, you can automatically create tasks in TickTick whenever you do things like save a message in Slack or star a new email.
TickTick price: Free version available; paid version from $2.40/month.

Best to-do list app for Microsoft power users (and Wunderlist refugees)
In 2015, Microsoft bought Wunderlist and put that team to work on a new to-do list app. Microsoft To Do is the result of that, and you can find Wunderlist's DNA throughout the project. The main interface is clean and friendly, adding tasks is quick, but there's a lot of flexibility below the surface.
But the real standout feature here is the deep integration with Microsoft's ecosystem. Outlook users can sync their tasks from that application over to Microsoft To Do, meaning there is finally a way to sync Outlook tasks to mobile. Windows users can add tasks using Cortana or by typing in the Start menu. For example, you can type "add rice to my shopping list," and rice will be added to a list called "shopping."
This is also the prettiest to-do list app on the market, in my opinion. You can set custom background images for every one of your lists, allowing you to tell at a glance which list you're looking at. You're going to be looking at your task list all day—it might as well look good.
Microsoft To Do integrates with Zapier, which means you can do things like create a task in To Do whenever important tasks pop up in your other apps. Here are some examples to get started.
Microsoft To Do price: Free

The best to-do list app with elegant design
Things (macOS, iPhone, iPad)
To-do list apps tend to fall into two categories: the complex and the minimalist. Things is somehow both.
That is about the highest praise I can give a to-do list app. This is an application with no shortage of features and yet it always feels simple to use. Adding tasks is quick and so is organizing them, but there's seemingly no end of variation in ways to organize them. Areas can contain tasks or projects; projects can contain tasks or headers that can also contain tasks; even tasks can contain sub-tasks if you want. It sounds confusing, but it isn't, which really speaks to how well Things is designed.
Other applications offer these features, but Things does it in a way that never feels cluttered, meaning you can quickly be done with looking at your to-do list and get back to whatever it is you're doing. Combine this blend of functionality and beauty with features like a system-wide tool for quickly adding tasks, integration with your calendar so you can see your appointments while planning your day, intuitive keyboard shortcuts, reminders with native notifications, and syncing to an iPhone and iPad app.
The only downside here is the complete lack of versions for Windows and Android, though this decision is probably part of what allows the team to focus on making such a clean product. If you're an Apple user, you owe it to yourself to try out Things.
You can automatically add to-dos to Things from your other apps with Things' integrations on Zapier. Here's some inspiration.
Things price: $49.99 for macOS (15-day free trial), $19.99 for iPad, $9.99 for iPhone
Best to-do list app for users with a very specific organizational system
OmniFocus (macOS, iPhone, iPad)
OmniFocus is nothing if not flexible. This Apple-exclusive application is built around the Getting Things Done (GTD) philosophy trademarked by David Allen, but an array of features means it can be used for just about any organizational system you can imagine. There are three different kinds of projects you can set up, for example, depending on whether you need to do tasks in a specific order or not. There are six main views by default, allowing you to organize your tasks by things like due date, projects, and tags. You can even add more views, assuming you have the Pro version.
You get the idea. OmniFocus is a power user's dream, with more features than anyone can hope to incorporate into a workflow, which is kind of the point: if there's a feature you want, OmniFocus has it, so you can organize your tasks basically any way you can imagine.
Syncing is offered only between Apple devices. There is a web version, currently in testing, but it's intended for occasional usage away from your Apple machines more than anything else. Non-Apple users should look elsewhere.
You can connect OmniFocus to your other favorite apps with OmniFocus's Zapier integration. Whenever something happens in another app that you want to keep track of in OmniFocus, Zapier will automatically send it there.
OmniFocus price: From $99.99 per year for recurring plan. Also available as a one-time purchase from $39.99 (14-day free trial).
Best to-do list app for making doing things fun
Habitica (Android, iPhone and iPad, Web)
Games are fantastic at motivating mundane activity—how else can you explain all that time you've spent on mindless fetch quests? Habitica, formerly known as HabitRPG, tries to use principles from game design to motivate you to get things done, and it's remarkably effective. You can add tasks, daily activities, and habits to a list. You also have a character, who levels up when you get things done and takes damage when you put things off. You can also earn in-game currency for buying offline rewards, such as a snack, or in-game items like weapons or even silly hats.
This is even better when you join a few friends and start a party. You can all fight bosses together, but be careful: fail to finish some tasks on time and your friends will take damage. If that doesn't motivate you, nothing will.
What's the downside? Habitica isn't a great to-do list for managing long-term projects, so you might need something else for that. But if motivation is your problem, Habitica is well worth a spin.
Habitica Price: Free version available; paid version from $5/month
Best to-do list app for Google power users
Google Tasks (Web, Android, iPhone and iPad)
Gmail and Google Calendar have long offered an integrated tasks list, but for a long time, there was no way to access those tasks on mobile. Google Tasks changed that, offering an Android and iOS version to complement the web version.
The app itself is spartan. Adding tasks is quick, particularly if you spend a lot of time in Gmail anyway, but there's not a lot of organizational offerings. There are due dates, lists, subtasks, and not much else.
So this isn't the most robust task list, but the best to-do app is one that's always handy. If you're the kind of person who always has Gmail open on your computer, it's hard for any application to be handier than Google Tasks. The mobile versions make those tasks accessible on the go.
You can automatically move information between Google Tasks and your other apps with Google Tasks' integration on Zapier. Here are a few examples of workflows you can automate, so you can stop manually moving your tasks.
Google Tasks price: Free
Best to-do list app for keyboard shortcut lovers
Remember the Milk (Android, iPhone and iPad, Web)
Did you forget about Remember the Milk? It's been a long time since this app got headlines, but it's been quietly competent all of these years. And it's still one of the best options for users who don't like taking their fingers away from the keyboard. The desktop version of this app makes it easy to add a bunch of tasks in quick succession, and there's also support for adding tasks using Alexa or Google Assistant.
But Remember the Milk also provides very straightforward mobile versions, as well as syncing with Outlook for Pro users. This means it's a great way to quickly add tasks and have them show up everywhere. Give this app a chance if you haven't thought about it for a while; it might surprise you.
With Remember the Milk's integrations on Zapier, you can automatically create new tasks whenever trigger events happen in the other apps you use most.
Remember the Milk Price: Free version available; paid version from $39.99/year
Best to-do list app for people who forget to use to-do apps
Any.do (Android, iPhone and iPad, Web)
Any.do offers a really slick mobile app that makes it quick to add tasks, organize them into lists, and add due dates. But where it really shines is with its daily "Plan my Day" feature, which forces you to schedule when you'll accomplish your various tasks so that you remember to actually do things. Any.do also integrates nicely with Google and Outlook calendars, allowing you to see your appointments and your tasks in one place. This is exactly what you need if you're the kind of person who adds things to a list and forgets about them.
The desktop version isn't quite as slick as the mobile version—it can feel cluttered, and doesn't offer much in the way of keyboard shortcuts. Still, Any.do's mobile version alone makes a compelling reason to give it a shot, especially if that's where you do most of your task management.
Any.do integrates with Zapier, so you can automatically add tasks to Any.do whenever there's a new calendar event, note, or task in your other apps.
Any.do price Free version available; paid version from $2.99/month
Other to-do list options
We focused on dedicated to-do list apps in this roundup, but plenty of other software can fulfill the same function. Here are a few ideas if none of the above quite fit what you're looking for:
Project management apps like Trello and Asana can be very useful as to-do lists, so look into those if none of these systems work for you.
Note-taking apps like Evernote, OneNote, and Google Keep can also work quite well.
Time-blocking apps are another solid option. These combine a task list with your calendar, encouraging you to decide when you'll work on what.
Sticky note apps can also work in a pinch. So can a piece of paper. Don't overthink things!
Finding the right task management system is hard because it's so personal. To that end, let me know if there's anything you think I missed.
