I am searching for a feature once provided by my Treo. I could enter a recurring task and it would remind me the task was due or incomplete at designated intervals until I completed it (without it having to be specifically snoozed). In other words, it would remind me of all past due tasks each day. And you could reset the repeat interval for the task by an absolute (every 7 days) or relative (from completion date) intervals. Is anyone aware of such an app for the iPhone?
