The Card Caddie
Stop losing money every time you pay.
What it does
Credit cards earn different rewards, and keeping track is tedious. The Card Caddie uses real-time, location-based rankings that show you exactly which card earns the most before you pay. 1. You tell us your cards - we never collect personal credit card info 2. We tell you which one to use - every time you shop, online or in-person 3. You save money - automatically, forever Every year, people miss out on hundreds in rewards simply by paying with the wrong card, we eliminate that waste.

- IBI built a tool to manage and compare credit card rewards2025 · rewards.getonecard.io · ▲87
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!
