I've tried so many and even programmed my own and none of them worked for me. I was especially disappointed in the ones that claimed to be AI-assisted.
I wrote one many times over during my career that was amazingly effective, not just for myself but others, too. I can't figure out how to write it for the phone because I am a crummy programmer. I would love to have it again. It had one feature that I am unable to find on any other to-do list app.
In my last version I had a single list of tasks, and each had a list of "excuses" which were pointers to other tasks. I had filters for showing "all tasks", "not done", "can be done". The one other feature that was helpful was being able to reorder tasks.
Maybe I will get back to work on it. I thought I had found a perfect set of alpha users in the /r/productivity sub, but I'm not on reddit anymore.
Yes, something like that is so helpful. Just even splitting something down into multiple steps so I will actually do it instead of staring at it in dread.
