Mac to-do apps are the best-looking software you can buy. Smooth animations, perfect fonts, a little checkbox that feels expensive when you click it.
We're not going to pretend that stuff doesn't matter, because it's half the reason you're searching. But the pretty app has a problem it can't fix from the dock, and it shows up every day around six.
What Mac people are really shopping for
Say "to-do app" to a Mac person and they picture something native. Fast, clean, keyboard shortcuts, at home next to the rest of their Mac. There's a whole family of apps like that, and some of them are genuinely lovely.
If you spend ten hours a day at that machine, wanting the list to feel good there is fair, because a clunky page you dread opening is a real cost. The taste is fine. It's the test that's wrong, because a to-do list earns its keep in the moments when you're nowhere near the dock.
The lid closes at six
Here's the day nobody designs for. You work at the Mac until six, close the lid, and head home. Somewhere on the way you remember the dry cleaning, the thing you promised legal, and your mom's birthday.
The beautiful app is asleep in your bag. Whatever happens to those three thoughts, it won't involve the Mac, and by the time the lid opens tomorrow, two of them are usually gone1.
So the Mac hours are when tasks get done, but the not-Mac hours are when they get remembered, and a list that only lives on the Mac misses every one of those.
Where the list should live on a Mac
While you're actually at the Mac, the list doesn't need to be an app at all. A pinned browser tab does the job and sits one keystroke away all day, and if your work happens in Slack, the list can answer you right there.
What matters at the desk is small. You can see today, add something in a few seconds, and check things off without ceremony. Almost any decent list clears that bar on a big screen, which is exactly why the desk is the wrong place to judge one.
The assistant that's already on your Mac
There's one Mac app that has quietly become a great place to keep a list, and it isn't a to-do app. It's the ChatGPT or Claude app you already have open.
42 Todo! connects to them through MCP, a standard that lets AI assistants work with other apps. So in the middle of whatever you were already asking, you can say "add a task: send the contract back, friday" or ask what's due today. It's your real list answering, not a note the assistant scribbled somewhere.
For a Mac person, that turns the native-app question inside out. The list doesn't need its own window when it's reachable from the window you're already in.
It has to leave the desk with you
Then six o'clock comes, and this is where the choice actually gets made. The same list that answered in the browser should be in the car on the drive home, on your phone in the store, and listening in the kitchen when you think of something while scrubbing a pan.
That's what we built 42 Todo! to do. There's no native Mac app to admire, and we're at peace with that, because at the desk it's a tab and an assistant away, and after six it's everywhere the pretty apps aren't. If you're comparing a few, judge them on the drive home instead of the fonts2.
The best list on a Mac is the one that's still with you when the Mac isn't.
Frequently asked questions
What's the best free to-do list app for Mac?
- If you live all-Apple, it's Apple Reminders. It's free, it's already installed, and the same list shows up on your iPhone. 42 Todo!'s free plan also works on a Mac through the browser and inside ChatGPT and Claude, with no time limit, so you can run both for a week and see which one still has your tasks in it.
Is Apple Reminders good enough on a Mac?
- For dated reminders and a shared grocery list, yes, and the location reminders are clever. It thins out when your day happens outside Apple's apps. It can't answer you in Slack, and it can't take a task from ChatGPT or Claude mid-conversation. If that's where your day happens, you'll feel the gap.
Does 42 Todo! have a Mac app?
- Not a native one. On a Mac you use the website, Slack, or the ChatGPT and Claude desktop apps, and most people just keep a pinned tab. We spent the effort on everything that happens after you close the lid.
Can I use the same list on a work Mac and my own phone?
- Yes, it's one list wherever you open it. Add a task in a browser tab at work and it's on your phone in the store that evening. A couple of named lists, like Work and Personal, keep the two sides of your life from blurring when you look.
