Apple

I use Obsidian : https://obsidian.md/ It's way more than just note and task, but I like the open structure of it. It's free

Apple Notes and Apple Reminder

Both are actually quite useful when you give them a chance. And I use them on a daily basis with lots of notes, documents, recipes, etc… Reminders for everything, even location based. It really has everything I need, they are ad free and I didn’t have to pay for the apps (besides the price of the iPhone)

Recently switched from Things to Reminders. Bought Things when reminders was lacklustre in features, but it caught up.

emacs org-mode. Along with beorg to sync with iPhone.

Things 3 or TickTick for todo items. Microsoft OneNote or Apple Notes for notes.

For notes, just Apple Notes. If I’m taking detailed notes rather than something quick, I use GoodNotes 5 on my iPad.

For tasks / reminders, I actually just find myself using my calendar, since I always go to look at it every day. I’ll set a time to do the task or when it’s due, and then I can set reminders in the calendar event as well. I’ve tried todo apps and reminder apps and such, but I end up forgetting to use them. 😐

I use Apple Notes and Reminders. The Reminders app is actually pretty robust and is also good for your grocery list etc. (you can add items via Siri). The main reason I use it is because reminders stay front-and-center on my Lock Screen even after I unlock and re-lock my phone. I have yet to find another app whose notifications don’t get buried in the Notification Center.

I use Apple’s stock Calender and Reminder apps, but I use the Onward widget to show them both together on my Home Screen and in Notification Centre.

The default Notes app and the default Reminders app. Does the job and works with Siri HomePod.

With the standard Apple Reminders app, you can link specific email messages to specific reminders, and then link back to the email. Major part of my workflow, and it works across devices.

Oh, and Apple Notes for notes.

I use apple reminders. For notes, it depends on what type of note. If it’s just a quick note on my phone, I use the included Apple Notes.

If I’m on my iPad with my Pencil, then I’m using Good Notes 5

I use microsoft to-do. Syncs with Outlook and the windows app.

Alright...

I share two lists in Reminders with my wife for groceries and things we could do.

My main everything To Do app is OmniFocus, because it's the only app I found that gives me a Deferred option. The idea is to be able to add a task and forget about for it for the time need.

I follow the GTD method and because I use OF to organise all of my projects, I have tons of ToDos and it can be really overwhelming. I used to procrastinate a lot because I hadn't a good view of what I could achieve. So it goes like this :

OmniFocus has some Views. The one I use are Projects, Contexts (or Tags) and Flagged.

• The Project View is bloated with all the tasks I have registered.
• The Context View allows me to sort my tasks by Capabilities on the moment (A location, a person, a tool, a period in the day etc) and add a first filter on tasks that can be done. For instance I might have a list of ordered tasks in some project that need to be completed one after the other, only the first task of the list will appear here. Tasks that have been deferred won't appear here either.
• The Flagged View displays the tasks I flagged, but because there is a deferred option I can flag a task without it actually showing up in my Flagged View. It will automatically show up the moment I decided it should.

You could argue that setting an alarm on a task would basically do the same thing. But the whole point is to decide when I should begin to start doing stuff. Alarms are stressful. I don't need an alarm for a task like "Clean the cat litter" or "Get the trash out". I just need not to forget, because I usually forget those things.

There are a lot of other things I do with OmniFocus, but this comment is long enough already.

I share some Notes too with my wife, but I use Notes mainly for very quick draft. I'll go with IA Writer for longer text, and with Day One for my diary.

I like google keep. Accessible from any device. iCloud.com always get clunky to me when working from a computer.
