My Best Card

This app keeps track of all the different reward levels for your credit cards. You enter a card nickname, a default reward amount and any reward amounts for specific categories. When you are out somewhere, a restaurant for example, you click "Best Card for..." then select "Restaurant" and up pops a sorted list of your cards with the best current reward for the category on top.

I wrote this app to be practical, not glitzy. Although it says it needs Internet permission, I don not actually use that. (It is an artifact of using App Inventor.) If you are worried I will steal your credit card information, the app doesn't even let you use more than 4 numbers in a card name.
