Big News Pro
For a less minimalist approach to news browsing, grab Big News Pro. The app connects to your Google Reader account and gives you a large scrolling look at the latest headlines from your feeds. Expanding the widget lets you see story synopses and images, too -- a nice touch that really pops on the lock screen.
Big News Pro has several customization options, including a choice of a light or dark color scheme or a completely transparent background.
The app costs $1.29. There's also a free version available, but its widget is more limited and doesn't include image support.
