Finally! EPI-USE Africa Pty Ltd has released GeeReader today which is a sweet Google Reader app for the BlackBerry PlayBook. It does not seem to cache articles for offline reading but it offers a sweet interface for Google Reader. It lets you login to your Google Reader account and view all your articles. The only things I found missing were the ability to add a new feed and share the item on Twitter or Facebook.
The app lets you click on any article in Google Reader and it opens up a smaller view showing the article. Once the window opens if you like to make it full screen simply tap the blue bar at the top.
Until then this is THE app to have on your PlayBook if you don’t want to use Google Reader in the browser. You can check it out at this link in App World or simply search for GeeReader.
