Reminder app that keeps alerting every 5 minutes or so until confirmed?

I've used rtm, todoist, and many others. Problem is it alerts once and, if I don't notice it, I don't get the reminder. It is in my notifications, but I don't look at my notifications. (you need to pull down... But out of sight out of mind.). Is there a reminder app that when I set a reminder, it will remind me every few minutes until I acknowledge the alert?

 

Forget it, I found an app that does pretty much what I'm looking for. It's called alarm and pill reminder. It continuously makes noise until you snooze or dismiss.
