This is a free tool that helps you manage and visualize your credit card rewards across different categories.
You can input the cards in your wallet and see how they complement each other, spot gaps in your setup, and also see the best card to use for a given merchant.
I’m also a founder at OneCard, where we’re building a smart card that’ll eventually handle all of this automatically, routing each purchase to the best card in real-time.
Would love feedback from the HN community!
