TeuxDeux is a simple list-app and the closest you can get to a paper to-do list, digitally. I keep my TeuxDeux as the browser landing page on my computer, which means, every time I open a browser window I am being reminded what I should be focusing on. Whatever you don’t check off today, will automatically roll over to the next day. It’s delightfully simple. And in the ‘someday section’ below I keep lists like shopping, movies I want to watch, gift ideas for the kids, etc
Try it for free! And if you do, do me a favor and enable the flying cat in the settings. You’ll see!
