I actually have given thought to writing an app that works along the same lines. A shared planner that someones and their groups can use. Take for example a household, everyone in the household can enter tasks, either their own or group tasks. When they do, they place a priority on them and a estimated time to complete. Tasks can have subtasks, this way a group of tasks can be rolled up into a task project. As well, scheduled tasks can be entered into it, that have very specific time requirements. Such as go to the doctor at X time/date. From there they system can generate a calendar of tasks that are to be completed. The user can then mark a task as completed or not, if it is not then the task list is recalculated based on priority and schedule tasks. I saw the same issue as the author, tasks have to transfer to the calendar, if they don't they get skipped. The thing that a system like this would do is show the aging of a task is being procrastinated on. The other idea that I had was to have a checkbox on every task that asked if someone could be hired to do a task. If the answer is yes and at a certain aging point, the app would ask if they want to solicit bids on the task, the app would then place the task in a market place where people could bid to perform the work of the task. This way people could hire to complete the task once they realize that it has languished in their queue.
