Ha! The web interface is probably not the best interface to emulate, especially not for mobile. If you're attempting to utilize Material Design, you should take a look at the metrics guidelines for creating a pleasing UI on the device.
Cool. I tried your app and went through the reddit posts too. I guess I'll post in reddit after fixing the current issues in few weeks(Have exams in next 2 weeks). Few more questions though.
* The login function isn't still available in official API?
* How did you promote your testing community(g+ page)?
* Login isn't through the official API, I just scrape what the website does
* There is an AlertDialog on the first run of the application that lets the user know about the G+ community
* Donations haven't been publicized yet (I only added the links a couple of weeks ago). I may publicize them soon, as the Heroku instance I'm running the server on may need to be moved into a pay tier.
