For the UI of the app, I wanted to aim for something simple and useable, function over form. There have been many interfaces throughout history that have been lauded for their simplicity, and for an app such as this it really was the only way to go.

It didn't take long before I had a sketch on a notebook. Functionally, the app needed 4 buttons: "Next Page", "Prev Page", "Refresh", and "Post" for the eventual writing feature. Following a common web design paradigm, I also included a "Home" button, ultimately in the form of the COSI logo, which translates to navigating to the most recent page, or refreshing the page if it is the current page.

The sign in functionality, as well as a possible settings menu, will be implemented in the menu that pops up when the Android "Menu" button is pushed. Though this button is deprecated in Android 4.0, less than 1% of all devices run that version, and it is backwards compatible with apps that use the menu button.

Here is a sample screenshot of the app's design, sans content:
