The Costa Coffee app is designed to enhance the coffee-drinking experience for enthusiasts. It offers a convenient way to collect Costa Club beans, order drinks for pick-up, locate nearby Costa stores, view beans balance, and exchange beans for free treats. By using the app, users can eliminate the need to carry a physical loyalty card and instead scan their phone at the till or Costa Express machines to earn rewards. The app also allows for mobile ordering, enabling users to skip the queue in-store or order from a Costa Express machine.

The app provides various features to enhance the user experience. Users can log in with their existing Costa Club account details, register an existing card, or create a new account. They can also use mobile ordering to order ahead and save time. Additionally, the app allows for one-touch contactless reordering from a Costa Express machine and the option to gift rewards to friends. Users can track their beans balance to know when they have enough for a free handcrafted drink and find details of nearby Costa stores, including directions, opening times, and facilities. The app also offers the option to add the Costa Club card to Google Pay for added convenience.

It's worth noting that the app utilizes users' Costa Club ID internally to provide more personalized content and rewards in the future. However, users have the option to opt out of data profiling by contacting Customer Services. While the app is not currently available for use in Northern Ireland, existing users are encouraged to provide feedback and suggestions for improvement.
