To-Dids is an unconventional style of to-do list, for repetitive tasks where it matters how long since they were last done -- not whether they got done the last time you put them on your to-do list. It might be how long since you mowed the lawn, or changed the oil in your car, cut the kids hair, checked in with a customer, or called your mother. Whatever these tasks are, the main view of the application presents you with a simple list, and the elapsed time since each task was last done.
To-Dids can be useful in reinforcing new habits, or even helping you to break old ones. You might use it to track how long it has been since you cheated on your new diet, or how long since you got inappropriately angry at someone.
Twitter Support
With twitter integration, you can make yourself accountable for public commitments. Whether its studying daily for an upcoming test, running to prepare for a race, or even a negative action like the last cigarette you smoked, To-Dids can update your twitter status to tell your followers about your progress.
Notes and Delayed Entry
You can choose to mark items complete at specific times, and provide notes with each completion. Note text is freeform, and can be used for anything from call notes to exercise duration, or study topics, etc. If you forget to mark a task complete, you can choose a time and date for the completion later.
