What’s New

The latest updates to CardStack, CardStack+, and the web experience.

Release notes

Major App Update: 1.4.0

Feature

CardStack just got smarter about your wallet.

Stack Insights

  • See exactly when the wrong card was in your hand. Stack Insights flags purchases where another card in your stack would’ve earned more, with cleaner swipe summaries and sharper Fix My Stack picks.

ROI, rebuilt

  • Your annual fee should earn its keep. We rewrote the math so every card tells you the truth.
  • One calculation, everywhere. Home widget and per-card totals now share the same fee-anniversary math.
  • Year-one credits count. Credits redeemed before your first annual fee posts now roll into that fee year.
  • Net Fee Offset. Green when you’re ahead, red when you’re not. No mystery.
  • Credits Available. What’s actually left to grab this fee year, in plain language.
  • Tap to see the math. “How is this calculated?” lives on every card. Tap the Home widget to flip it open.
  • Pro tip: set Card Opened and Next Fee Due on each card to unlock the most accurate, anniversary-aware numbers.

Swipes, leveled up

  • New Summary, Transactions, and Fix My Stack tabs. Filter by date range, missed vs. optimized, category, or card. Faster everywhere.

Credits

  • Cleaner review flow when a linked account surfaces a credit that needs your eyes.
  • New filters by status, card, and category.

Points Tracker

  • New Bonuses view.
  • Active transfer bonuses surface automatically.

Offers & Extension

New cards, better matching

  • Sharper matching for Amex 5-digit wallets, Chase parallels, and the weird edge cases.
