Cuppa - Coffee Loyalty App app for iPhone and iPad

Our coffee-based loyalty app lets regular customers in local cafes avail free coffee, tea, or fast food once in a while. The app constitutes a simple sign up page, once signed in, the camera gets turned on to read the QR code held by Barista/cafe manager, once scanned, the customer gets a point for that particular cafe, after certain points(lets say, 7), the customer can redeem their free cup of coffee as a reward for their loyalty towards the cafe.
The camera page also contains the list of all cafes with details of points availed & purchases in the slider at the footer of the page. The app is in MVP mode and its design is efficient, relevant, and customer-centric.
