Very customizable, from which tasks and projects you want to see to which attributes of to-dos should show in each view to endlessly nestable folders
Lets you plan your to-dos and calendar events around each other
Helps you review your projects regularly
Has “sequential projects” that hide tasks you can’t work on yet—for less clutter
Excellent support for attachments
Cons:
Apple-only, web version is limited
UI not as intuitive as other apps
Scheduling a task ahead of time could be more intuitive
Great for: people in the Apple ecosystem who want to customize their to-do app exactly to their liking. Also great for people who want to closely follow the GTD methodology. See also: my OmniFocus 4 course.
Very minimalistic: forces you to focus on the most important tasks
Supports notes and sub-tasks, but it’s hard to spend an excessive amount of time organizing your to-dos when you’re using Tweek
Looks clean
Plan your to-dos and calendar events around each other
Looks like a paper planner; has a beautiful printable version
Cons:
Very minimalistic: makes it hard to track tasks like “buy pet food”. It’s not the most impactful tasks of the week, but you have to do it, and until you do it, it’s there in your mind, potentially distracting you.
Limited options for repetition schedules
Great for: people who want a digital to-do app that feels like a paper planner.
Best first-party app: Apple Reminders (Apple only)
Pros:
Comes with your Apple devices
Templates feature lets you create re-usable lists
Smart lists let you see just the to-dos you need to see
Excellent integration with some other Apple apps, e.g. sharing from Notes or Maps to Reminders
Very easy to capture to-dos to Reminders with Siri
Cons:
Apple-only, of course; web version on iCloud.com is limited
Smart lists not as customizable as in other apps
No integration with your calendar
Interface sometimes finicky; it’s not always intuitive what happens when you click or tap somewhere
Great for: people in the Apple ecosystem who prefer to avoid third-party apps when possible. See also: my Apple Reminders course.
Best combination task manager & calendar (for time blocking): Akiflow
Pros:
Fantastic time blocking implementation
No need for a separate calendar app
Separates start dates and deadlines
Great built-in rituals for starting and ending your workday
Cons:
Mobile app is not polished yet
Deadlines are not prominent enough
Limited options for organizing your tasks into buckets
Limited custom repetition schedules for tasks
No support for location-based reminders or file attachments
Lets you turn Outlook emails or Teams messages into to-dos
Has a built-in view showing your flagged emails
“My Day” is handy: automatically shows due tasks but you can also add other tasks to your day
Intuitive organization with groups and lists
Suggests tasks based on what you’re doing in other Microsoft apps
You can collaborate by assigning tasks to others. To Do will also show tasks assigned to you in Microsoft Planner.
Cons:
I’ve never been a fan of Microsoft’s design. For example, every time I click on a view, it prompts me to add a task. I often just want to view my tasks, darn it!
Not enough custom repetition schedules
Limited integration with Outlook calendar: you can see to-dos on calendar dates, but you can’t time block
Great for: people in the Microsoft ecosystem who get many of their to-dos from emails and from Microsoft Teams messages.
Best for lightweight task management with Google tools: Google Tasks
Pros:
Lets you turn Gmail emails into tasks
Lives in Gmail
Really lightweight and easy to use
Available on all platforms
Cons:
If you’re like me, you’ll find it a bit too basic
There’s just lists, tasks with optional subtasks, and time-based reminders
Not even a “today” view
No attachment support
Great for: people in the Google ecosystem who get many of their to-dos from emails and need nothing more than a couple of very simple to-do lists.
Handy quick open feature for fast access to to-dos, projects, etc.

Also lets you create documents
Excellent automation support for both internal actions and integration with other apps
Available on all platforms
Cons:
Steep learning curve
Interface can feel overwhelming
Great for: teams who want to manage their projects and to-dos in detail.
A note about pricing
You’ll notice I haven’t commented on prices. You should decide for yourself what a to-do app is worth. I’ll just say that better productivity and organization can be worth a lot.
P.S. Some links on this page are affiliate links, which means that if you sign up for an app, I may be compensated. I only recommend apps that I love, though.
