Development of a MVP Unified Loyalty Card App for iOS and Android

We are looking for a developer to build an MVP mobile application that consolidates various loyalty cards from Germany, Austria, and Switzerland into one app. The app's primary focus will be on usability, allowing users to securely add and store multiple loyalty card information and easily view balances and rewards. The interface should be user-friendly, accommodating both Android and iOS platforms. Further enhancements will be considered based on user engagement and feedback.
