Works well, but needs some fix – Wallet by CreditCards.com Review

The app is great and works exactly as promised. But there are Some place where it can improve. 1. Many cards are missing in the directory 2. It is a bit partial towards American Express, as my other card does a cash back match for all purchases, which turns out to be more meaningful to use that card Over Amex for same cashback. But wallet recommends Amex.
