WordPress is from long time ago NOT just a blogging platform but perhaps the best CMS I ever used. And it's not have to be "just" that.
I've made a little Web App that runs on every browser as well mobile platforms. It can also be installed on iPad and iPhone.
The App it's fun easy to use and is possible to create your own version and share it with your friends.
It is 100% built on WordPress!
