- Better on iOS 27: CardStack now works better with Siri AI, Shortcuts, Spotlight, and onscreen actions. You can quickly check credits, review spending, find offers, and jump straight to the right card or benefit. - Connect CardStack to your favorite AI Assistant: ChatGPT, Claude, Muse, and other agents can now help you maximize your credit card rewards through the CardStack MCP. - Use the annual fee you actually pay: Enter your real annual fee, including waived or discounted fees, and see which credits help offset it. - More accurate rewards estimates: Choose your Bank of America rewards tier, U.S. Bank Smartly tier, or Coinbase One tier so CardStack can estimate your earnings more accurately. - Find cards faster: Browse popular cards, filter by issuer, and request a card if you can’t find it. - Points syncing is more reliable: Fixed issues where balances or rewards programs could disappear or revert after edits. Wells Fargo Rewards is now supported too. - Credit tracking is more accurate: Improved how CardStack handles anniversary-based and six-month credits, remaining balances, and redemption history. - Better card matching: Connected accounts are less likely to be matched to the wrong card or issuer. - More cards, better data: Added more cards and refreshed benefits, earning rates, card artwork, and transfer bonuses. - Welcome bonus tracking is more accurate: Fixed reward amounts for offers with multiple spending requirements. - Got an idea?
