Why is it so difficult to find the CURRENT APR for the Apple Card???

All you need to do is go to the Wallet app and tap the card. After that choose the circle with 3 dots on the top of the screen and choose Card Details. You will see the APR rate when you scroll down to see the card details.

And if it’s the current rate for new applications, it’s included in the agreement:

And at the enrollment website, in the fine print: Variable APRs for Apple Card range from 19.24% to 29.49% based on creditworthiness. Rates as of February 1, 2024. Existing customers can view their variable APR in the Wallet app or card.apple.com.
