I had made an android app for the Google Technology User Group (GTUG) Philippines. It contains blog posts and the latest messages from our mailing list. There is also a tab for links to our online presence. To download the app, check it out in the Android Market or you can scan the QR code below:
Also, I have also made a Google Chrome Extension for the group. The initial version has been published last January. Now, it is in version 1.6 already. The extension is available in the Chrome Web Store. Users can get the latest blog posts, mailing list feeds and tweets. It also contains GTUGPH links.
