This FAQ post was much needed. Thanks for taking out the time. I have used this app myself and I liked it. I have made some suggestions as well.

I was actually not aware of the 5% reward thing. May be I missed it or didn't pay attention to it in the Terms and Conditions while I installed the app. Would suggest you to highlight this sufficiently, so that people don't hold it against you or the app.

All the best with the app. I can't wait for the desktop version to come out.
