Use This Card

Stop leaving rewards on the table. Use This Card tells you exactly which credit card to use for every purchase. Add the cards you own and instantly see which one earns you the most rewards for groceries, dining, gas, travel, Amazon, streaming, shopping, transit, rent, and more. No accounts. No bank logins. No personal data ever leaves your device. Add your cards, pick a spending category, and see your best card in one tap — with the exact reward rate and key benefits shown right away. Swipe through categories to scan your whole wallet at a glance. Put the Use This Card widget on your home screen and see your top card for each category without even opening the app. It refreshes automatically in the background so it's always up to date. Want to know if a new card is worth adding? The Wallet Optimizer scores your current lineup and highlights which spending categories have gaps, so you can make smarter decisions about your next card. The card catalog covers dozens of popular rewards cards — Amex Gold, Chase Sapphire Preferred, Citi Double Cash, Capital One Venture, Apple Card, Discover it, and many more — and updates in real time. Your card list is stored only on your device. No account required. No personal information collected. No data sold. Ever.
