A friend showed me this app and I have been using it for a couple weeks now and have earned $5 in Google Play credit. The questions are very simple. One asked me to prove I was paying attention and click the 5th star. It earned me 28 cents I believe. I seem to be getting about 3 questions every couple days. Most have focused on stores I have visited because it knows my location. Above I earned $0.15 for admitting I went to the party store and rating my experience.
