User should be able to add more than one text on the card. user should be able to download or share the card via apps. users should have their own account panel. they should be able to review their cards and other related histories on the app. users should also be given the opportunity to buy premium cards for a little cost and edit them to meet their requirements before they share it with their friends and family. there should also be option to add a background music with some cards if possible. I should have my complete admin panel and a very well organised dashboard so i can add all my cards on the app and do other changes from my back end uses should be able to register on the app using their social media accounts.
