My wife and I use Cozi (free tier) for shared lists and calendar. Now we both will know when we need laundry detergent and that we have to meet up with whoever next week even if it doesn't come up in conversation. You can notify each other of calendar additions too, so that side of it doesn't even rely on checking that often.

For simple chores and errands, we just have a white board in the kitchen. We are cute and leave each other notes on it sometimes too.

All the apps... and none of them work for me.

But one that is nice, powerful, and still free usable without working with a 'hello world build a todo application'-app and seems to work for people that actually use todo applications.

Tasks.org and easytodo.

I have multiple

• Microsoft ToDo
• Clickup
• A discord channel
• Joplin

And I also use pen and paper

I use them all. Don't ask me why I can't stick with one, because I don't know. But my system works.

My nextcloud + Deck

I carry my field notes and a pen

Bitwarden notes

Reminders on the iPhone. It does everything I need it do. I’ve got my basic reminders, and I’ve got my shopping list. All my interaction with it is verbal.

When I arrive at the store I just say “show me my shopping list”.

A bullet journal. I can't get distracted and doom scroll for hours in a notebook.

Apple reminder. It syncs with nextcloud ( unfortunately no sub tasks possible) but i am using icloud. The app itself is pretty descent with some cool features

Markor

I use neorg for neovim, specifically I use:Neorg journal today to open up a daily .Norge file that I maintain notes, todo, etc on.

If I need to leave a note for myself for the future, I create a note for that day ahead of time.

jtxBoard on Android

Clickup. Technically it's a project manager, but it's relatively cheap and I've been using it for years now.

Google Tasks. Love that it syncs to Google Calendar.

Haven't seen Habatica mentioned at all. Sort of gamifies your tasks.

Material files. It has a text editor for my todo.md.
