I am creating a mobile styleguide that will make it easier for other departments to design apps similarly - not totally the same as in using the same template. Eg. using standard colors in jewels, backgrounds, common fonts, etc. Since it's pretty new, I am having hard time looking for a good styleguide examples. I am not looking for a guide for developers but guide for another to design another app using the styles set.
It's not for an app but the style guide for Starbucks' responsive site is incredibly useful and worth emulating.
