I am announcing the release of my latest iPhone and iPod touch application, Portal. Portal, when opened, loads some of the most useful sites on the web: ESPN, CNN, Digg, Meebo IM, the suite of Google webapps, and much more, including a page that has links to hundreds of mobile websites across the Internet. Currently, Portal costs 99 cents, and it is available at this link: iTunes Store

Mathemagician, a math study guide, is also on the App Store. It can be downloaded from the following link: iTunes Store
