I admit this does accomplish the motivation to routinely complete certain tasks. The problem I have with productivity tools is that they can't take into account all the constraints that are important: type of tasks (routine tasks + 1-time tasks), categories of tasks (project-related, home, work, hobbies), priority of tasks (most important to least important), time sensitivity of tasks (now, today, tomorrow, whenever) as well as size, scope, yada yada yada. Various tools seem to accomplish some but not all of these. What I am left with is a handful of tools that I get notifications for and am feverishly trying to check and manage. Productivity has now become managing all these productivity tools. Still waiting for that killer app that can match my (and I'm sure others') complicated mental model.
