Can I dismiss an alarm before it goes off?

I would like to be able to dismiss my morning alarm if I wake up before it goes off, without having to turn the alarm off and then back on once the alarm time has passed. Is this possible? Is there any app I can download that has this feature? I loved this feature with my android and used it often. It is so helpful to be able to prompt an alarm to avoid disturbing others that are still sleeping without having to remember to reset your alarm every day.
