Today I remembered an iOS app that I tried years ago, but didn't love as my main day-to-day tasks list. But, I realized that it could work well as a tool for this specific purpose. The app is called "Clear."
It's pretty simple to use and has a nice tutorial to get you stared when you first launch the app. It's easy to insert listings somewhere in the middle of the list, the downfall of the paper list. It color-codes each task from urgent to less-so... nice since the listings that are due first are the most urgent!
I'll include a screenshot of what I just set up today... transferred from my old spreadsheet. I figured it was worth sharing - If I've been looking for a better solution, maybe others on here were, too.
Happy New Year!

I am using Freemind on a linux desktop, but the link is a google search for mind maps ios. They are really fast and simple, though sometimes they appear quite complex, that's the beauty of them. Once you learn the principles, you will see the potential for all sorts of uses!
