Understand your credit cards

Rewy tracks the benefits, fees, and reward categories of 30 major US credit cards from 8 issuers. When an issuer quietly changes a benefit, we catch it and publish the diff.

Why Rewy?

Card benefits change constantly. A footnote moves, a multiplier drops, a credit resets — and nobody tells you.
Existing trackers have agendas. They earn affiliate revenue and surface the cards that pay them, not the ones you own.
Rewy is the change-log. We publish a public, diffable history of every card change. Nobody else does this.

How it works

Our data pipeline fetches from free public sources daily, normalizes everything against a strict schema, and commits every change to Git. The iOS app reads the same dataset and alerts you when your cards change.
