My problems with task managing apps, are not the apps themselves. Well, maybe a little. I always say things like, "I would commit a hundred percent to X app if only had a Windows app". Even when they do, I fail at them. Again, is not the app, it is a hundred percent me. I am awful at managing tasks, I forget to write down or add things to my task manager or notebook. If I do happen to add things, I forget to check and forget I have things in said system. 

It is not the app failing, I think. It is me, the problem. 

Wish I had more discipline in this regard.
