I downloaded this app yesterday when I received my loyalty card, which had two purchases on the card. The app said the card was invalid and then wouldnt let me leave feedback. Basically, the app may be okay unless you have a problem so they need to fix that. If I cant get my issues resolved, Im more likely to not use the app and be forced to use the less convenient card
