Reminders in ios

I would like to request an improvement to the iOS reminders. Whilst the app is vastly improved, it is still missing a very core feature. It needs a nagging feature where a reminder alarm will repetitively repeat until a reminder has been attended to. I know it currently can repeat hourly before the scheduled reminder but it needs to be done on a much more frequent basis with an option to snooze until marked as completed. The reminder should also repeat after the task time has passed until marked as completed. The reason I say it is core is because a reminder app is of no use if it does not repeat until you are reminded, otherwise you can still forget.
