This app has great potential but is not there yet. Example, if a task repeats but without notification, then you manually mark it completed. The task is shown as completed & should advance to the next scheduled date. Instead it is showing up the next day as past due. But, if the task repeats with notification, then on the due date/time the system instantly advances the due date but does not show the task as completed so you have no record of the task due today & I have overlooked many. Not good!
