Smart Alarm?

Hi Guys,

I'm trying my first Windows phone (Lumia 900), and I was wondering if someone can recommend a good smart alarm clock. I was using the built-in alarm in Android (GS Note), and I really love how the smart alarm work. Instead of blasting me with a blaring alarm, it will start off with a dim light, softer sound, and progressively get louder/brighter.

Is there such app for the Lumia?

Thanks in advance.
