Which Card?
Answers "which card should I use for this purchase" from your own wallet: the card whose rewards are worth the most on the purchase, not just the biggest multiplier - including any grandfathered rate you still hold. Sync a card and the answer also reflects the category caps you have already used. Free with an account; enter cards by hand or connect a bank.
