Cant seem to work it

I may not be as savvy as the rest but I think Im pretty good at figuring out out to use apps and this one doesnt seem to work. Even had the lady at the store try to figure it out and she couldnt. It doesnt seem to be a "tap and go " type app. Like a lot of the other bar scanning apps. Good price and great cause but could be easier to use.
