Basic iPhone app page for Sunrise calendar app. Good example of how little info you can get away with when you have a video along with a screenshot slideshow.
This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this Archive.org link. FYI: the site was first featured on 23 April 2013.
