My friend Michael Douma developed an app that shows how the genre can demystify complex concepts and make them simple and approachable.
The culmination of the effort is an app that not only packages the web site but allows for a new level of interaction to educate and illustrate the reasons for the confusing and frustrating ritual of changing of the clocks.
By adapting web content to interactive app content, the concept leaps off the screen. You can learn about the rationale of clock changes, get the historic perspective, the international variance, be alerted to the shifts, alert others and, of course, find out when the change happens no matter where you (or your friends) are.
Check it out, SpringAhead $1.99 on the App Store.
 I was modestly involved in the concepting.
