[Just Blanton on why he loves the repeating notifications in Due.app][1]:
> As you can imagine, this is great for (recurring) tasks that don’t necessarily need to be completed by/at the specified time, but instead can be done within some hours-wide window; e.g., a daily workout routine, weekly status updates you send to your manager, a reminder to call a friend on Saturday (set it for 9AM and have it bug you every hour until you do it), etc.
I actually didn’t know Due.app had a notification that would *keep* bugging you… Is that new? Anyways it sounds fantastic, and it would be great if all to-do apps had this functionality.
