Original title (Productivity isn't doing more) please

I emphatically disagree with the premise. Sometimes high performance comes from focusing on the small picture of just what needs done today. Or just what you want to do today. Or what you can do today.

The big picture does matter. Priority does matter. So this UX has a valid use case. But that use case is about making sure things progress and you don't utterly forget something important.

Also, this quote: "Other apps push you to get more done."

Again, big disagree. My to do list doesn't push me, it is a just a list. Even the management of my property (which is large because I own a forest, wetlands, some small ag, outbuildings, and the actual home), which I run on a Kanban board doesn't push me. It just organizes it without a timeline. If anything, this app is far more pushy than anything I do today.

In other words, this really smells like one person's personal organization style. If they find other people with the same style, they may find a market, but I suspect they will instead find that there is a reason that seemingly every coder has at one time or anther written their own To Do app. Because everyone wants something different.
