The Problem is not the quality app but the adoption rate. There are already tons of UPI apps available and none so far have been successful (Bhim, Phonepe and paytm are top 3). Google is already is late to the game. So, If Google wants this to make it hit, it really needs to heavily market it. Otherwise It would be like another futile attempt to switch Indians to digital payment systems, which currently, they are reluctant. I have high hopes for this one.
