I don't know if that's really a either/or question with scheduling timespans and due dates, and warrants a separate app.

When I add a task to Todoist, the suggested due dates are "Today", "Tomorrow" and "Next week", which already fills my need for rough grained due dates (since as a procrastinator I rarely even think about next month or next year in terms of todos). I highly suspect that it's not the only to-do list app that does it like that.
