I'm currently developing an app with a priority based system. Currently, it has basic features of priorities, but it will have more priority features later on in the year or by next year. :) It's called Goal Striver and it's free to download. There are a few bugs that I'm still working on.
I recently spent 4 months straight working on a task manager app called Goal Striver as well as acquiring users and creating blog posts. Basically my attempt at making a startup. I also learned a few new skills along the way.
Because of this quote, I created an app over the summer that is a to-do list app that forces the user to set deadlines for every task they create. You can check out the app here.
As long as you have some way to organize your thoughts and tasks, anything is fine. Even writing things down on a piece of paper and circling tasks by priority works! Also, if you don't mind, maybe you can try out an app I recently made over the summer that may or may not work for you.
The main benefit of having a calendar filled with stuff you need to do is it gives you a better idea, a bigger perspective of visually being able to see what you have to get done by when.
Don't worry too much about the system, you can always experiment a variety of ways and see what works and what doesn't. That's what I do.
I use Goal Striver, my Android alarm, and the 80/20 rule.
