Is there a Ring/vibrate timer app for Windows phones?

[Windows Central Question]

Ring/vibrate timer

I used to have a handy app that would put my ringer to vibrate at set times. So when you?re in a class it?s on vibrate and when you?re on brake it rings. I always forget to silence my ringer. Does anyone know of an app for windows phone that?ll do this?

All I got is this: Quiet hours and Cortana on Windows Phone | Windows Phone How-to (United States)

Doesn't help much, I know. I don't know of an app that can modify ringer/tone unfortunately.
