I ran into a problem - there are too many bank cards. It became difficult to keep in mind where which category gives more cashback.
Therefore, I made an application that considers which card to pay for me.
All you need to do to get started is to create cards in the application, add data about the increased cashback, about the basic one - and then on the main screen, select a category or enter the name of the store. The application itself will compare all the cards and conditions, and then suggest how to pay.
