When UOB Mighty was introduced last month, I was pretty excited - particularly because the previous mobile app was a nightmare to use. As I was getting my morning coffee from Patisserie G this morning (and I paid using my UOB Preferred Platinum Visa for 4 miles per S$1 of course), I received a notification from the UOB Mighty app for a review. According to UOB, UOB Mighty will give you S$5 for each restaurant review you submit.
